Repair your Bay Area Parking Lot with Calvac Paving!

Effective asphalt maintenance is an essential element in keeping curb appeal up and costs down for developers and stakeholders while creating a smooth driving surface. By improving drainage, preventing dirt and debris buildup, and retarding deep crack formation, a proper maintenance program, including regular sealcoat and patch repairs, extends the life of your parking area and helps prevent costlier lot repairs, saving management time and money while leaving you with more happy customer and tenant reviews of the lot’s condition—and your business!

Calvac Paving specializes in asphalt parking lot maintenance which helps prevent alligator cracks, raveling, and deeper cuts caused by cold, water, and UV rays. 

In this blog article, we’ll discuss why it’s easier to maintain asphalt parking lots than to have to do a full-scale asphalt repair and how Calvac Paving can help you get the maximum life and performance from your asphalt installation!


Pavement Maintenance 101: Why Does It Matter?


Parking lot maintenance is much easier when the parking lot paving is done right the first time by the paving company. When the asphalt installation is done properly using appropriate paving materials on the suitably prepared ground with a proper drainage plan, you get a permanent surface that performs the way you, and the people who drive on it, expect. This also decreases the likelihood of ruts and depressions developing that could later grow into large potholes, which could require expensive pothole repairs or even complete surface replacement down the road.

How the hot mix asphalt’s surface is placed makes a difference too! When done properly, most asphalt parking lots are placed in at least two layers of material, known as “lifts.” Each layer, or lift, will usually be left at least one inch thick after the placement and compaction phase, although this depends on the type of traffic and design elements the project calls for. This two-lift placement creates a smooth, stable base for your parking lot paving, which is flexible enough to withstand traffic wear while still being durable enough to stand up to both environmental and human-driven conditions. Often, a series of test protocols are carried out to ensure the paving contractor is using the right materials and placing them in the correct manner to make the surface as durable as possible. In many cases, a hot pour sealcoat, or asphalt overlay, is applied after final compaction but before the line striping is done to further preserve the surface.

 Drainage is important because it helps prevent rain, snow, ice, dirt, and other weather-related debris from building up on, and penetrating into, the asphalt surface. Regular pressure washing in conjunction with good drainage helps ensure this type of debris, plus vehicular fluids such as leaking gas and oil, carelessly discarded food waste left behind by visitors, and decaying vegetation like fallen leaves are washed away before they can damage the asphalt’s surface or degrade the parking lot striping through oxidation or acid erosion. Once this type of damage begins, it can quickly lead to parking lot cracks and asphalt paving failure. Even with the relatively mild temperatures and weather in the Bay Area, freeze-and-thaw patterns can quickly turn a minor crack just an inch or two long into a much larger and more expensive headache for your property and roadway safety.


I Have a Crack in My Asphalt. Now What?


A well-maintained parking area doesn’t happen by accident. Keeping a close eye on your pavement, especially around concrete curbs and gutters, seams, and drainage courses, is a critical component of parking lot maintenance which can help you detect developing problems early so they can be taken care of. Parking lot cracks can be easily dealt with using a hot rubberized crack filler, which helps seal the crack and prevent it from growing larger or spawning new tributary cracks. Because it requires less personnel and equipment, parking lot crack sealing also tends to be much cheaper than having to do a patch repair on a failed area of asphalt, a pothole repair, or asphalt milling and resurfacing a new top course, including fresh asphalt sealcoating. This type of crack repair also generally takes a lot less time and is less intrusive to the traffic flow of your business.

As a best practice for parking area maintenance, it’s usually a good idea for you or your maintenance staff to walk your lot at least once every month just to check if your parking area needs lot repair. 

When you identify areas that could lead to cracks and potholes, such as an area of cracked sealing, you should contact Calvac Paving right away so we can get you the best possible asphalt solutions before the problem gets out of hand. Sometimes repairing the issue can be as simple as applying crack filler or hot or cold patch asphalt to shore up a weak area. Like a crack filling, asphalt patching in one or two isolated is a whole lot less expensive, intrusive, and time-consuming than it is to repair or replace an entire parking area!

Frequently Asked Questions About Parking Lot Repair by Calvac Paving

Calvac Paving is here to help with straight answers and honest information about your paving needs, big and small!


Question: What causes alligator cracks, and how do I know I need parking lot repairs because of them? –Srinivas, East Oakland, CA

Answer: Alligator cracks, which take their name from their resemblance to the scaly hides of alligators, usually form because the subgrade wasn’t properly placed or compacted or because the material under the asphalt has been undermined by water and debris infiltration. If you notice alligator cracks in your parking lot, you definitely need to have the area repaired as soon as possible before it becomes a pothole—or worse. In cases like this, one common approach is to cut out the failing section, rework and recompact the subgrade, and then place a patch over the affected area. This approach helps to shore up the failed area and prevent the damage from spreading further. However, it may not be necessary to take such drastic action in all cases, which is why you should have a qualified contractor like Calvac Paving evaluate the situation before you take action.


Question: Can I do parking lot repair myself? –Justin, Sunnyvale, CA

Answer: Depending on the type of issue you’re having, it’s possible—but you’re probably not going to get the same results as you would by engaging an experienced contractor to take care of it for you. This is not to say you’re not perfectly capable, but you likely don’t have access to the tools, machinery, or personnel to get the job done right and make sure it doesn’t become a recurring issue. More importantly, while a DIY video on YouTube makes repairs like this look straightforward and simple, they can be challenging and lead to further problems if they’re not addressed properly. Ultimately, you’ll get better and more reliable results using an experienced contractor like Calvac Paving than if you try to handle the issue yourself!


Question: How does maintenance prevent parking lot repair? –Judith, Palo Alto, CA

Answer: Just like your home or your car, preventative maintenance, like keeping your parking areas free of debris and chemical spills, can help extend its lifespan and ensure optimum performance longer. For example, if you had a crack in a window, you’d likely notice a higher energy bill and poorer performance from your climate control. In the same way, a small crack in your paving can lead to a big problem down the road because asphalt isn’t self-healing, and cracks don’t get smaller over time. Instead, they get wider and deeper, and if allowed to continue, can lead to serious failures such as potholes and even subgrade degradation. That’s why it’s so important to take care of issues like this early before they have a chance to grow and spread into more serious issues!


Question: What should I look for when I’m doing parking lot maintenance to avoid needing parking lot repair later? –Adam, Mountain View, CA

Answer: Some key points to look at when you’re doing parking lot maintenance include items like:

Is the area clear of debris, including discarded food and other organic material?

As organic materials decay, they release chemicals that can eat away at the asphalt sealcoat and, later, the asphalt itself. A blob of ketchup from a carelessly discarded packet may not seem like a big deal, but that tiny blot of tomato paste could lead to a pothole years later, which is why it needs to be cleaned up as soon as possible.

Do you notice dirt or sediment building up along drainage channels?

This could be an indication of warping in the asphalt matrix and/or a clogged storm drain, which could lead to asphalt failure if it’s not attended to promptly.

Do you see motor oil or other vehicle fluids on the paving?

Like organic material, over time, these can eat away at the bituminous (tar) binding that gives asphalt its flexibility. This makes them particularly inimical to even the most perfectly executed paving jobs. It’s important to clean up such spills quickly, so they don’t have a chance to cause problems that could lead to expensive repairs later!

8 Signs Your Asphalt May Be Failing

Asphalt is a very versatile and durable paving material. Its resilience and flexibility make it an ideal surface for everything from eight-lane superhighways to driveways to parking lots. However, asphalt does require care and maintenance to function at peak performance, and it can fail for a number of reasons. If you see any of these warning signs of failing asphalt, quick action can save you a lot of time, money, and hassle. Here are eight signs your asphalt may be failing—and what you can do to fix them!


1.  Alligatoring

Alligatoring is called that because of its appearance: interconnected cracks that look like alligator skin. It is an indication of load-related deterioration which could be caused by a weakened or improperly compacted subbase material, excessive traffic loading, inadequate pavement thickness, or a combination of these factors.


2.  Edge Cracks

Edge cracks are found within 1-2 feet of the outer edge of the asphalt surface, running longitudinally, or roughly parallel to the outer edge. These cracks are caused by improper support of the paving surface at the margins.


3.  Reflective Cracks

Reflective cracks most typically form in joints or areas of concrete or asphalt paving which have been previously repaired, such as with crack sealing or where a temporary corrective overlay has been placed to relieve stress on deteriorated paving. These cracks form because of continuing movement of the old pavement due to continuing traffic load.


4.  Slippage Cracks

Slippage cracks are easily identifiable because of their crescent shape. They occur either due to poorly bonded pavement layers or an asphalt mix design which is insufficient to the demands of the traffic patterns. These cracks appear because of forces applied by turning or braking vehicles, which cause the pavement to move slightly at first but with accelerating damage to the surface the longer the underlying cause goes uncorrected.


5.  Rutting and Depressions

Rutting is caused by weakness of the subgrade or base soil layers, instability of an asphalt mix, insufficient pavement thickness, or poor compaction. Rutting is a linear, surface depression of the wheel path caused by deformation or consolidation of any of the pavement layers or subgrade. Depressions, also known as birdbaths, are localized areas of pavement surface failure caused by poor initial construction techniques that undermine the asphalt over time. These may occur on their own or in conjunction with other failure indicators. If left unchecked, depressions can become potholes (see #8).


6.  Asphalt Patch Failure

These failures are easy to spot because they’re very localized to the area where a patch was placed, and characterized by unevenness, deflection or stress cracking along the perimeter of the patch. They are caused by either not fully removing the damaged area to be patched, or not allowing a minimum of one extra foot around the perimeter of the patch area to ensure the patch is bonding to an uncompromised surface. The rate of patch deterioration is influenced by materials selection, compaction, and the quality of the surrounding pavement as well as the underlying subbase. While the latter is not typically visible, adding one additional foot around the patch can help patches last longer and function better under load.


7.  Raveling

Raveling is caused when the aggregate particles in the asphalt cement wear away under traffic forces. This condition suggests either that a poor-quality mixture was used or the asphalt surface has hardened enough to no longer be supple and flexible.


8.   Potholes

These bowl-shaped holes are caused by localized disintegration of the pavement surface. Potholes are usually the result of another type of distress that has not been properly addressed. Segregation, failed patches and cracks can all lead to a pothole over time. Weak spots and localized areas of improper or insufficient compaction in the subgrade or subbase, or poor asphalt mix designs, can accelerate degradation of the pavement surface and the formation of potholes.


When you notice indications of paving failure, bring in an experienced paving contractor as soon as possible to restore the surface and minimize downtime, expense and the risk of further, more severe failure in the future. Calvac Paving has been proudly serving the Bay Area and beyond for over 45 years, and we’d like to put that experience to work for your next paving repair or new construction project.

Owner Tami Adam notes that Joe’s tenure as CEO was never intended to be permanent. “When Joe agreed to step in as CEO, it was always meant to be a temporary appointment. The company was in a difficult transitional phase, and we hoped that Joe would provide some stability while we prepared the company for the next CEO. When the time was right, we began our search for the right candidate.”

For Tami and Joe, the quest to find the perfect person for the CEO role was a lengthy and arduous one. The journey entailed interviewing dozens of candidates and reviewing hundreds of resumes, all in an attempt to find a candidate with the right mix of experience, education, professional knowledge, and culture fit to continue to deliver the unparalleled service and outstanding results our clients have come to expect. Ultimately, the candidate field was whittled down to Dan Garson, who has executive leadership experience in the paving industry in the Bay Area and holds a BS in Chemical Engineering as well as an MBA. But it wasn’t just impressive credentials that got him the position. Tami says, “When we met with Dan, it became very clear that his depth of knowledge and experience would be a great asset to Calvac. We also saw that his personality and disposition would be a perfect fit for our company culture. [This mix] is what set him apart.”

For his part, Dan is excited to roll up his sleeves and get to work in his new position. “I am committed to growing [Calvac Paving] by building upon the success and reputation created by Tami, Joe, and Jim. They have established a great roadmap to use as a tool to build upon a well-established foundation. I could have said they have helped to pave the way for me, but I thought better of it,” Dan added, demonstrating his trademark dry wit. He notes that his primary vision for the company is to “continue to focus on delighting our current customers with our excellent quality, responsiveness, and service and build on that reputation to grow our business in the same way with new customers.”

Asked what his top priorities are for Calvac Paving currently and in the months and years to come, Dan cited recruiting, employee retention, client base outreach, and of course, across-the-board growth. “A current priority is to grow our estimating and operations teams,” he said. “We have excellent opportunities for the right people who exhibit the passion, commitment, and dedication required in our business for our customers. Calvac, Inc. provides a rewarding career, competitive compensation, and an excellent culture for employees to thrive,” including an outstanding safety record and benefits, which interested applicants can learn more about by clicking here to contact Calvac Paving.

Obviously, the question now becomes what’s next for Joe and Tami! 

For her part, Tami will remain with the company as owner and CFO. In her words, “It is important to all of us that Calvac remains a family-owned business in the true sense of the phrase. We are committed to retaining a personal connection between ownership and every employee at our company.” In this role, she will be working closely with Dan to ensure continuity, stability, and the observance of the core principles Calvac Paving has embraced to the benefit of its staff and clientele for nearly 50 years.

Meanwhile, Joe has plans of his own. While he will remain chairman of Calvac Paving’s board of directors, he will be relocating to Oregon with his fiancée in the near future. This means his involvement in the company’s day-to-day operations will be drawing to an end. Everyone in the Calvac Paving family wishes Joe and his bride-to-be all the best in their future endeavors and a long, happy, and joyous marriage!

Maintenance Mondays -Your Sealcoating Matters-

Helpful Tips sign Sealcoating is an important process in the maintenance of your all too expensive parking lots.  We all know that the costs for paving repairs have increased.  This makes it all the more important to protect and preserve your asphalt surface.  Calvac Paving has been applying sealcoat for over 45 years, longer than most Bay Area Suppliers have been making asphalt based sealcoats.  Each successive generation of sealcoats has provided greater protection from premature wear, moisture intrusion and oxidation.  Even with these improvements we strongly recommend the addition of latex and sometimes sand to the existing asphalt sealcoats to extend the life expectancy of these applications.  It is also vital for you to have your contractor apply two coats of sealcoat to your property.  The first coat, with the added sand and latex, is the filler coat and allows placement of a second coat with added latex only or wear coat.
Preparation of the existing asphalt surface is a very important process in sealcoating your parking lot.  Calvac Paving will spend the time necessary to clean and prepare your asphalt to assure a durable and attractive product. We will remove all vegetation, and apply herbicide if appropriate.  We will use Power blowers, scrapers, wire brushes and brooms to thoroughly clean the existing asphalt.


This preparation may also include Mobile Sweepers, water trucks or buggies and vacuum trucks.  We will burn, scrape and carefully clean the oil spots and apply an oil spot sealer with sand.  We will mask utility covers and other structures to protect against coverage.  We will apply hot rubberized or coldpour emulsion crackfiller as directed.
The consistency of the asphalt sealer is also very important to the durability of your sealcoat project.  Calvac Paving will never exceed the manufacturer’s recommendations for dilution.  This addition of water is necessary for the application and actually improves the bonding to the existing asphalt surface.  We feel the addition of latex and sand to the asphalt sealer extends the life of the sealer, and we include these admixtures in well over 90% of our sealcoat projects. By extendeding the life of your sealcoat surface with added latex, you reduce the number of times you will need to seal coat and stripe your lot as well as impose upon your tenants over the life of the asphalt.
The combination of effective barricading and traffic control with superior craftsmanship and products will provide you with the best result with the least impact upon you and your tenants.



Maintenance Monday: Don’t Let Poor Drainage Take Your Parking Lot Down The Drain!


With the wetter, cooler conditions of fall upon us and winter in full swing, it’s a good time to check your parking lot and other asphalt applications for signs of poor drainage and damage. It’s much easier and less expensive to catch a problem early and correct it than it is to wait until that small cracked area spreads to half the lot. With this in mind, here are four signs you should look for to check if your parking lot drainage is working as it should.


  1. Rocks or sand in unusual places

If, after a heavy rain, you notice rocks or sand in low-lying areas, this may be an early warning sign that something’s wrong with your drainage. The water from the rain may actually be eating away at the asphalt and flushing away the solid particles of sand and rock aggregate that make up asphalt. To make sure it’s not runoff from the street or areas higher up, look for consistent ripples or waves in the deposits which are larger at the higher end and taper off toward the lower side of your lot. If you see this, your lot is probably okay, unless you see large areas where the sediment and rocks have gathered. This indicates possible low spots which could cause problems later.


  1. Pools of water or flow down the middle of the lot

Most asphalt parking lots today are designed along a slight but apparent slope to facilitate runoff. Likewise, they are usually built with an engineered high point called a “crown,” which is intended to direct water away from the middle of the lot and down toward the drain points. Pooling and water flowing directly down the middle of the lot suggests the crown has been compromised or a possible issue with the subgrade, which will need to be addressed before the asphalt begins to buckle.

  1. Cracking

If you start to see cracks developing, especially in areas where you also see heavy water flow and/or residue such as described above, this is a sign the asphalt is beginning to fail because the water is breaking down the bitumen binder. This may also be a sign of traffic outside the asphalt’s design tolerances being present, such as large amounts of heavy trucks or construction equipment. In either case, once cracking begins, water can infiltrate the asphalt surface and accelerate the rate of failure, making repairing it a priority before it gets out of control.



  1. Are your drain inlets working as they should?

Periodically, it’s a good idea to check your streetside and in-lot drainage inlets to ensure they’re clear of obstructions and debris which may prevent them from working as expected. In many cases, asphalt failure can be traced back to a blocked drain inlet which hasn’t been corrected. Regular property walkthroughs can help you spot problems like this before they become severe enough to warrant repair or rehab of your parking lot, and keep it working the way you expect it to for years to come.

How Many Parking Spots Will I Need For My Strip Mall?

Happy Monday Everyone! In this edition of Maintenance Monday, one of our social media friends sent us this question.  I own a strip mall in San Jose, we have 10 retail stores, with 75 parking spots. How do we figure out the correct amount of handicap parking spots to have?  The answer is…

Thank you, In this case, 75 stalls. Three would need to be accessible spaces (not handicap), of which one of those would have to be van accessible.  One thing to consider is the current count. If this property has 5 existing accessible spaces, it is best to put back those 5.  The reasoning is that the standards are the minimum and it is not usually a good idea to decrease accessibility on a property.  This is why it is important to plan these layouts with an ADA specialist, you don’t want to create a problem in the future by guessing or overestimating today.

How many parking spots do I need?

Frequently Asked Questions about Asphalt Repair Near Me


Calvac Paving is your Bay Area asphalt repair company for all your questions and answers about getting your pavement repaired the right way with lower repair costs and greater performance for years to come!


Question: How much do asphalt repairs cost? –Nicholas, Santa Clara, CA

Answer: Most cost guides put the asphalt driveway cost at between $0.75-$2.00 per square foot, and about $40-$80 per ton, depending on the location, accessibility, job size, and similar factors. From this math, you can figure a ton of asphalt will cover anywhere from 40-100 square feet. An asphalt driveway repair and complete redo on an area of 20×25 square feet (500sq.ft. total) may require anywhere from 5-11.5 tons or more, depending on the intended depth of the mat for the blacktop driveway, the size of the aggregate (rock) in the matrix, and the price of crude oil at the time the asphalt is ordered.

However, what the guide won’t tell you is the linear footage you have to cover, which is determined on a per-case basis. This calculation doesn’t factor in related cost points, such as whether you need to bring in processed soil (Type II) to compact into place for your aggregate base course before placing the asphalt. For a roadway, the math is a little different, and a sidewalk changes the equation yet again. A roadway or parking lot may be significantly cheaper per ton of asphalt than a spot repair on a sidewalk or a driveway repair at a house out in the sticks. Whatever the job type, when you contact the paving company nearest you for an estimate, they should be able to help you filter all these factors so you can feel confident that you’re getting a fair price for the work you need.


Question: Why do I need to worry about repaired asphalt anyway? –Billie, San Jose, CA

Answer: There are a lot of very good reasons you may need or want paving repairs, resurfacing, or a complete tear-out and rebuild. If you’ve got widely varying heights between areas of asphalt, especially if you notice significantly lower spots forming, this could be a sign of water infiltration washing away the fine aggregates in the base course under the asphalt, which could lead to potholing and major safety issues such as trip and fall injury risks that you or your company could be liable for. If you notice significant cracking or warping, you may be getting traffic on your pavement that’s too heavy for the asphalt mix to withstand, such as parking loaded semis on residential driveways. This could also be a sign of tree roots working their way to the surface and cracking through the asphalt in search of nutrients, which is really hard on both concrete and asphalt paving. In some cases, the application of sealant can help manage cracking and prevent it from getting worse, especially if it’s set early enough in the crack development process.

These are all valid reasons to consider getting standard or infrared repair for your paving as soon as possible, depending on the size, type, and severity of the damage, including appearance, curb appeal, and shielding yourself from unnecessary liability claims. But did you know that keeping your paving in good condition is also a great weed control measure? It’s true! If the seeds of weeds can’t reach the open air, with its water and sunlight, they can’t grow. Whether you’re a die-hard horticulturist or perfected the art of the brown thumb, this will help keep your property and your paving looking and performing better for years to come.   


Question: How do I screen the results when I look up contractors who do asphalt repair near me? –Beaujolais, San Francisco, CA

Answer: Reputable paving brands in the Bay Area know that having a great online marketing game is only half the equation. Fast response, efficient methodology, and great results make up the other half. You can sometimes get a sense of what a contractor’s like online from the stories reviewers tell about them, but these should be taken with a grain (or, in some cases, a whole shaker) of salt. It’s human nature to only focus on the unpleasant parts of an interaction, even if the result came out fine in the end, and it’s simply not realistic to please everyone all the time. Because of this, it’s important to remember that every “bad” story has three sides: What the person telling it says happened, how the other party saw it, and what really happened.

A paving company whose policy and work ethic favors customer service, efficiency, and a great project resolution will typically have better reviews than one that doesn’t. 

However, they also typically have longevity on their side. It’s rare for a contractor who doesn’t routinely do excellent work to last a decade in this business, let alone FIVE decades, as Calvac Paving has. If they sell a solid range of services, that’s also a good indicator that you can trust them to be knowledgeable about a wide range of paving-related issues and how to resolve them economically. It doesn’t do you any good to have asphalt repair near me only minutes away if they’re not going to do a good job for you, your customers, and the public. That’s why, when you’re deciding which paving contractor to trust for your pavement repair project, if you want the guaranteed best results, you should contact Calvac Paving as your first and last call!


Question: We just bought a new house in Harrisburg, and we’re looking for a driveway repair near me. Can Calvac Paving help? –Saint Croix, Harrisburg, CA

Answer: Calvac Paving is considering expanding our paving job offerings to include residential driveway work. We don’t normally do that sort of small-scale work as of the time of this writing, but we’d like to encourage you to be sure to check back often as this may change. Thanks for keeping us in mind for your asphalt repair needs, and be sure to contact us for the latest menu of residential and commercial paving repair services!


Question: How can I tell if my chosen company for asphalt repair near me is doing a good job? –Clovis, Oakland, CA

Answer: Sometimes, it’s not always obvious to a layperson’s eyes if the contractor is up to the job. However, there are a few ways you can tell easily whether your contractor is giving you great work or a big runaround!

Your paving repair company doesn’t explain the jargon they’re using.

They may talk about warping, raveling, cracking, alligatoring, or undercutting, all of which are legitimate paving problems that have distinct causes and specific solutions. But when you ask what these terms mean, they give you a vague answer, tell you to check out their company website, or just wave at the area in question and say, “That.” A reputable paving contractor has a vested interest in educating its clientele about the various problems that can occur with paving, why they happen, and what you can do to help prevent them—after all, it’s their reputation on the line if their work doesn’t hold up under the strain of traffic, seasons, and years!

They don’t try to work with your schedule and the needs of your business.

Sometimes a section or even an entire parking area or lane of the roadway may have to be closed off for paving work to proceed. A reputable paving contractor will do everything they can to balance efficiency and safety with getting the job done in a way that doesn’t have an undue impact on your business or customers, but sometimes this can’t be avoided. When it is necessary, your paving contractor will work with you as best they can to make sure that the work is done as quickly as possible while guaranteeing the ideal outcome for your project.

They riff off a figure for paving repair—and then change their estimate in the middle of the job.

Sometimes, of course, this can’t be helped either. The cost of crude oil is one of the major components in pricing asphalt. If crude oil prices shoot through the ceiling between the project’s bidding stage and the middle of the construction or asphalt repairs, then obviously, the price of the project may have to increase as well. However, a reputable contractor will do everything they can to provide a bid that accounts for these unknowns and builds a reasonable cushion into their pavement repair cost estimates. Calvac Paving is known for rarely having to submit a change order during construction—and on the rare occasion we do, it’s almost certainly due to circumstances beyond our control, such as a delay in local permitting or similar issues which hold up the project.

As you can see, there are a few red flags you should look for when deciding on a company to execute paving repair near me. Or you can save yourself the headaches and the risk altogether and just contact Calvac Paving in the first place! Our dedicated team of trained, skilled, experienced paving professionals has all the tools, knowledge, and capabilities to manage your asphalt and concrete paving repairs in a way that’s on point, on time, and on budget.

Calvac Paving Deploys Trash Capture Devices Inside Catch Basins to Combat Water Pollution

Our water is arguably the most precious natural resource we have, and it’s up to everyone to keep it clean so we always have access to safe drinking water. At Calvac Paving, we’re always looking for new ways to help keep our environment clean and healthy without compromising performance. Recently, we added a new tool to our arsenal in the ongoing fight against water pollution: full trash capture units inside catch basins.

If you’ve been walking down the sidewalk or happened to look at a storm drain in the middle of a parking lot recently, you may have noticed a marker which reads, “No Dumping—Drains To Bay,” such as a stream, lake or the ocean. Other such markers include reminders to be cautious of discarding trash and debris into water sources. All of these markers indicate places where trash capture filter devices may have been installed in storm drains.


The principle behind trash capture units inside catch basins is very simple. They work much like a pool filter to prevent dirt, debris, garbage and other runoff contaminants from getting into the water. Made by REM Filters, these Triton filtration systems are designed for drains which empty to stormwater repositories and water bodies. They have the advantage of being economical, flexible and relatively low-maintenance, while helping keep stormwater runoff cleaner and promoting a healthier environment.

With different filtration media available, property managers, owners and municipalities can design a custom system which works with the primary contaminants in a given area, such as streets, parking lots and garages, food courts, sidewalks and so on. The filters are easy to clean, change and service, allowing for broader application with reduced service and personnel costs versus conventional storm drain clearance procedures. Even better, Triton trash catch basins can be applied to both new and retrofit construction, saving time and money over other stormwater mitigation measures.

Calvac Paving has been serving the Bay Area for over 45 years with the latest and best in paving and stormwater mitigation technology. Some of the services we provide include:

·        New Construction 

·        Grading

·        Concrete Placement

At Calvac Paving, we are committed to providing the best and most modern paving solutions available, while implementing new ways to make our processes and products greener and more in harmony with our environment. There’s no “Plan B” for our planet; we only have one, and it’s everyone’s responsibility to help keep it green, healthy and beautiful for ourselves and generations to come. New technology and pollution-combating policies, processes and procedures are just one of the many ways we demonstrate our commitment to a greener Earth on every job, every time.

Bay Area Asphalt and Concrete


5 Major Asphalt Advances to Watch in 2022 From Calvac Paving

From the highway to the driveway, asphalt paving gets you where you need to go. Humanity has been using asphalt and bitumen for projects as diverse as waterproofing, shipbuilding, and road paving for millennia, and it has continued to prove its utility at every turn. In 2022, Calvac Paving is excited about some new advances in paving technology that could be game-changers for drivers, owners, stakeholders, and local, state, and federal authorities and agencies alike. These are the five major asphalt advances you’ll want to watch in 2022, brought to you by your friends at Calvac Paving!


Alternative paving materials


From cigarette butts to recycled plastic to rubber-modified asphalt (RMA), scientists worldwide are exploring the application of old materials, used in new ways to enhance the strength, longevity, sustainability, recyclability, and resilience of asphalt paving. These alternative paving materials may help combat issues like the “urban heat island” effect, keeping asphalt-paved surfaces cooler and allowing them to trap less heat year-round. They also offer new ways to reduce waste, reuse materials, and recycle “junk” materials that are typically discarded, helping break the waste chain and creating a healthier environment by keeping these materials out of landfills, waterways, and oceans.


Smart pavement


Technology may soon make your morning commute or your summer trips safer and easier, with fewer bumps and less noise! Integrated sensors that report everything from traffic conditions to overall roadway and pavement health are being tested around the globe. Nanoparticle-based noise- and vibration-damping adhesive binders for asphalt mixes are under investigation as a potential solution to problems such as roadway chipping and pitting. And roadways that charge electric vehicles as they drive using wireless recharging technologies are in active use or the planning stages from Sweden to Michigan to Norway, solving one of the EV’s biggest hurdles while also making paving even more environmentally friendly!


Asphalt continues its reign as the world’s most recycled material.


Roughly 100 million tons of asphalt pavement mix are produced each year globally. Of that amount, an estimated 95% is reclaimed, reused, recycled, or repurposed, making asphalt one of the planet’s most readily recyclable materials. Perhaps most importantly, recycling asphalt helps keep costs lower and reduces reliance on foreign oil to create the bitumen binder that gives asphalt paving its flexibility. With all these factors going for asphalt, it’s reasonable to expect even bigger pushes to maximize asphalt recycling up to a full 100% in 2022 and beyond.


Inflation and rising oil prices


Between the war in Ukraine and US embargos on Russian goods, including oil, the continuing effects of the COVID-19 pandemic on shipping and trade, and a period of high inflation, prices are only getting higher for just about everything—and asphalt pavement is no exception. Recycling and the use of alternative paving materials will help offset this increase greatly, but paving contractors and stakeholders can still expect to see reduced profits and higher up-front costs, at least through the summer.




Some of the biggest advances and hottest trends in paving technology don’t really have to do with the pavement itself—but the paint! Striping is a perennial headache for entities from the federal government all the way down to small business owners trying to keep their parking stalls and handicapped spaces ADA compliant, but new formulas and application methodologies appear poised to change that in 2022. New advances in striping paint include more eco-friendly options, nanotechnology and microfibers for increased durability and longer utility life, and additives and refined formulas for heightened visibility. Autonomous, self-piloting robotic paint sprayers which deploy striping more uniformly, more accurately, and with a greater level of precision than humans are capable of are making a big impression across the industry.


At Calvac Paving, we’re excited about (most of) what 2022 has in store for the paving industry, as well as how new advances and technologies are going to change both the paving industry and the face of our world. Since 1974, we’ve been committed to making the use of concrete and asphalt paving in construction as efficient, cost-effective, and environmentally friendly as possible. Because of this commitment to a greener, cleaner planet for all, and better-forming pavement applications for our customers and stakeholders, we’re looking forward to seeing the next big advances and putting them to work!

“Green” Paving?

While this phrase may sound oxymoronic, asphalt pavement has consistently been reported as the most frequently recycled material in the nation since 1993. Continuous improvements in recycling technology and paving practices and techniques that permit for more adaptive uses of existing paving materials have fueled this recycling boom with regards to asphalt and, to a lesser degree, concrete. Purely virgin asphalt concrete, also known as “hot-mix,” is relatively rare today because of the numerous advantages of recycling asphalt in place. However, many old-school pavers often still refer to “warm-mix,” discussed below, as “hot-mix” regardless of this designation’s true accuracy.

“Overall terrific experience. Responsive, engaged and high quality work. I would definitely recommend Calvac to others.” 

Most asphalt you see on the road today consists of rocks, also called aggregates, sand, binder material, and additives such as shredded rubber tires, pig manure, cigarette butts, and metal slag, to name a few. These additives are re-purposed and treated in such a way as to make them a cohesive part of the overall mix and increase a Bay Area asphalt and cement mix’s performance. This transforms relatively useless or even outright hazardous materials into reasonably safe and effective filler materials for asphalt mixes. However, the most common fillers are recycled asphalt paving and asphalt shingles. Using these materials in “warm-mix” asphalt paving sharply decreases the amount of virgin oil binder needed to create a safe driving surface with proper internal cohesion and compactive properties.

According to the National Asphalt Paving Association, in the 2013 construction season alone nearly 68 million tons of recycled asphalt and almost 2 million tons of asphalt shingles were used as recyclables, at a savings to taxpayers of around $2 billion. The use of recyclables has increased 21% since 2009 and represents over 99% of all in situ, or existing, asphalt paving and concrete being recycled and re-purposed instead of ending up in landfills.

Calvac Paving is proud to be part of an industry that is able to recycle and reuse apparent waste materials so efficiently and effectively in concrete and asphalt paving. 

As your Bay Area concrete and asphalt pavement provider, Calvac Paving takes a deep interest in ongoing advances in procedures and techniques that allow for new ways to re-purpose existing pavement, whether it is asphalt, concrete, or something else.

 The Future Of Asphalt & Concrete

The interest in new advances is not limited to asphalt because Calvac Paving is dedicated to finding more efficient and ecologically sound ways of achieving the same overall goals. One development that Calvac Paving is watching with great interest is so-called “bio-concrete.” In this type of concrete, a regular concrete mix is impregnated with tiny plastic capsules containing a type of bacillus bacterium which feeds on calcium lactate and excretes limestone. The capsules dissolve when exposed to water, activating and freeing the dormant bacteria within to begin the healing process. This landmark technology could result in admixtures for other types of Bay Area paving, which work to increase the strength, performance, and longevity of all kinds of paving while reducing necessary time-of-life repairs dramatically.

As paving technology and techniques evolve, Calvac Paving intends to retain our leadership position in adopting new practices, prioritizing greater safety, security, durability, and environmental awareness in every task we undertake. From new builds to maintenance and repair of existing paving projects, Calvac Paving wants to ensure that its products and services stand the test of time, just as we have since 1974. For your next paving project, whether you’re starting from scratch or trying to determine the most efficient and effective way to repair or replace worn, cracked, or improperly placed paving materials, Calvac Paving’s experienced personnel can become stakeholders in your properties.

Question: How can I tell if my Bay Area asphalt and concrete company is going to do a good job? –Arthur, San Jose, CA

Answer: A reputable paving contractor will have a good rating with the Better Business Bureau; solid reviews on Yelp!, Google, HomeAdvisor, and other contractor-oriented websites; and be able to provide honest reviews and references from actual customers so you can verify their credentials and past experience. However, is this the best way to gauge how a contractor works? Not necessarily! The best way to see how a contractor does their job is to actually see them working and how they interact with their crews, other contractors, inspectors, and the general public. This can help you evaluate both the content of the company’s character and the sort of results you can expect from your Bay Area paving contractor. Or you can just contact Calvac Paving!


Question: How does recycling asphalt make for a better environment, and why does Calvac Paving care? –Alisha, San Francisco, CA

Answer: Conserving natural resources to create a healthier environment and future for everyone who shares this planet has been a priority goal of Calvac Paving since the beginning. As such, we make it a point to source our cement-based concrete and asphalt concrete from recyclable materials when and where possible. We also work hard to keep up with the latest changes and developments in concrete and asphalt technology, so we’re always at the forefront of innovation for paving that delivers superior longevity, durability, performance, and safety for the general public. But it’s our results and impressive list of repeat customers, some of whom have trusted Calvac Paving’s personnel, methods, and processes for decades, that really sets us apart from other so-called “green” paving companies. That’s why more businesses and contractors trust Calvac Paving for eco-friendlier construction materials and practices and why you can trust us too!


Question: What is the difference between asphalt, concrete, and cement? –Jonas, Santa Clara, CA

Answer: Cement is one of the key ingredients in concrete. When you mix Portland cement with aggregate, sand, admixtures, colors, and other ingredients, you get a simple-to-place matrix that can be tinted, colored, shaped, and formed in just about any way you can conceive of. Thus, while you can have cement without concrete, you can’t have conventional concrete without cement. 

Asphalt, on the other hand, uses sand and aggregates as well, but it substitutes a bituminous binder, also known as tar or oil, for cement to give the matrix greater strength, flexibility, and water resistance. When the asphalt is compacted and cured, it forms a flexible surface that can withstand more direct force for longer periods than concrete can. This is why you see concrete curbs alongside asphalt roads and driveways. The concrete helps to shape and support the roadway, while the asphalt provides a smooth, resilient surface that’s safer to drive on in all weather and easier to repair than conventional concrete. 

Unlike some companies that only do one or the other, Calvac Paving places both Bay Area asphalt and concrete paving so you know you’ll get the best results every time.
