Bay Area Asphalt Contractor Completes Latest Project

IMG_7684At Calvac Paving, we love a challenge. When St. Francis Retreat in San Juan Bautista needed an overhaul of their existing roadway, we were pleased to lend our experience and expertise to the task. The retreat is in a secluded rural setting just outside the town proper, which created some specific concerns we needed to be cognizant of during the project.

Working in a rural area, we had to plan our work in such a way as to minimize the impact on the environment and existing flora and fauna, as well as ensure we avoided disruption of the operations and tranquility of the Retreat itself as much as possible. In addition, we had to consider the safety of our personnel and the general public. Finally, the historic nature of the Retreat had to be taken into account and treated with respect.

The roadway is approximately 1 3/4 miles long and required 2,300 tons of hot-mix asphalt. The rehabilitation consisted of pulverizing, regrading and compacting the existing asphalt as additional base material.  Then we laid replacement hot-mix in one 3” lift, compacted.  

We are pleased to report the renovation operation went very smoothly. The local residents, staff and visitors were very patient with the unavoidable disruption a project of this sort involves. We were able to complete the project ahead of schedule and within budget, without injury or harm to the area or anyone involved in or affected by it. Best of all, the Retreat now has a great-looking, high-performance roadway which can be expected to last for years to come.

Maintenance Mondays -Your Sealcoating Matters-

Calvac Paving Slurry Seal

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.

IMG_3641

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 Mondays – Drive Lanes Removed & Replaced

Maintenance Mondays: This project was for a Medical Building. This required the crew from Calvac Paving to work on a Sunday to minimize disruption. The bulk of the drive lanes were damaged to the extent that we had to remove and replace approximately 45% of the drive lanes. The crew completed approximately 260 tons of removal and replaced with 260 tons of hotmix asphalt. All of the removed asphalt was hauled to a recycle plant. Our crews were completed and out of our yard and on their way home by 6:30pm.

Bay Area Golf Course Asphalt Repair

At Calvac Paving, we know a thing or two about asphalt repair and Golf Courses. So when Poppy Ridge Golf Course called us to bid on a project to rehab an extensive areas of failed asphalt encompassing the road leading to the golf course and the parking area itself, and to reseal and restripe the parking area and drive entrance, we were pleased to submit our expertise and cost for consideration. Soon thereafter, we learned we had been awarded the project at 4280 Greenville Road in Livermore.

To achieve the repair, we provided 4” asphalt repairs and two coats of seal followed by restriping. This required excavating the failed asphalt and recompacting the subgrade beneath the asphalt paving. Then the hot mix asphalt needed to be placed in two 2” layers, or “lifts,” using 3/4” asphalt on the base lift and ½” medium asphalt on the surface lift. Covering 4,000 +  square feet of surface area. This ensures strength, flexibility, and density within and between the asphalt layers, while minimizing air voids which can facilitate water infiltration and lead to premature asphalt failure over time. 

Once the subgrade and the lifts had been individually compacted, we provided two coats of Reed and Graham’s OverKote, an asphalt emulsion seal for asphalt which incorporates a latex additive. This step gives a smooth, finished appearance to the asphalt, adds surface resiliency and increases water and dust resistance, extending the operational lifespan of the asphalt.

The staff and patrons of the golf course were extremely cooperative and understanding of our schedule and the project went very smoothly. We’re proud to announce that Poppy Ridge Golf Course has already recommended us for similar projects on the strength of our work here, and we’re excited to be able to demonstrate the quality and efficiency of our work once again.

Calvac Paving And San Harbour South HOA : A New Parking Lot Case Study

 

Calvac Paving recently undertook a paving rehabilitation project for the San Harbour South HOA  association located at 906 Beach Park Boulevard in Foster City, California. The existing pavement was over 45 years old and was starting to exhibit severe cracking and base failures.

Calvac Paving setting up Primary Client Concerns

The primary client concerns included:

  • Continuous access during the milling, repaving and striping operations

  • Cost

  • Schedule and time management

  • Quality surface at the project’s end

Proposed SolutionIMG_1971

After reviewing the jobsite in person, we came up with a range of possible solutions that would meet the client’s needs.

Calvac PavingDue to sub-grade issues. We proposed milling the existing pavement down 2” from the existing surface and laying approximately 2,500 tons of ½” aggregate hot mix, in addition to the replacement of 1,500 linear feet or 90 cubic yards of concrete valley gutter. Our recommendations and proposed fix were accepted by Calvac’s client and HOA Board. The job was undertaken in phases as to not disrupt the community at one time.

Final ResultsFinished Project Piece

The end result of the San Harbour South HOA project looked fantastic! The project went off without any difficulty and was completed within the stated schedule and budget.

Maintenance Monday: 10 Ways to Prepare Your Asphalt for Summer

Calvac Paving Bay Area Asphalt and Concrete Contractor

 

Whether it’s a roadway, a driveway or a parking lot, asphalt takes a pounding over the fall and winter months. The cooler temperatures and more frequent rains can take a toll on even the most robust and well-constructed asphalt pavements. To ensure maximum safety and durability for your asphalt and the people who travel and park on it, Calvac Paving presents ten ways to prepare your asphalt for summer!

 

1.  Take a Closer Look.

Asphalt is very durable and resilient, but there are a number of ways it can fail, so it’s a good idea to have a thorough walkthrough at least quarterly. You should check the condition of your asphalt more frequently in cases of unusually heavy or inclement weather, or if you notice indications of a problem like water flowing down the middle of your lot or roadway.

 

2.  Cracked-Up Asphalt isn’t Funny. 

Surface cracking often indicates that the subgrade beneath the asphalt is failing, this will also allow water penetration into the subgrade. In these cases, depending upon the severity, the affected problems such as potholes, alligatoring, or area(s) need to be removed and replaced.

 

3.  Paint it Black.

If your asphalt looks gray rather than black, has a pitted look or you notice deep cracks which may allow water to infiltrate to the subbase, it’s time to engage in crack filling and sealcoating, to help preserve and protect the asphalt and retard further damage. 

Note: Most unsealed asphalt has a rough and somewhat textured surface, because of the placement methodologies and the type of hot mix used. The larger the aggregate in the mix the stronger the pavement, but you give up the smooth appearance

The solution to this rough surface is twofold. First, an admixture of 2% latex per gallon of raw seal coat is added to both coats of material. secondly, adding one to four pounds of sand to the seal coat on the first coat will add necessary fine aggregate to fill the voids in the asphalt pavement. No sand is added to the second coat. This works to ensure a better looking, longer-wearing surface.

4.  Don’t Stand for It!

Standing water can be a symptom of subsurface issues with a section of your asphalt, usually caused by compaction failure in the subbase. Not only can standing water erode the surface as we’ve already discussed, but it can also undermine the integrity of other sections as the water is forced out of the depression and follows the drainage profile of the area in question.

 

5.  Rainbows Belong in the Sky, Not on Your Asphalt!

If you notice iridescent or rainbow-colored patches, these should be cleaned off as soon as possible. Oil and fuel spills can degrade the asphalt’s surface quickly, creating imperfections which over time can become full-fledged failures, reducing your asphalt’s performance and lifespan. 

 

6.  Clean it Up.

In addition to the fuel and oil spills mentioned above, it’s always a good idea to keep your asphalt clean and clear of debris such as garbage. Food products, in particular, should be cleaned up quickly, because these tend to have a relatively high acid content, e.g., ketchup, hot sauce, salad dressing, which then lingers on the surface, promoting deterioration of the asphalt. Besides, it just looks nicer!

 

7.  Root it Out.

If you have trip hazards such as uneven areas or raised roots, now is an excellent time to get them corrected. Trip hazards can be an expensive liability and can presage surface failure later depending upon the nature, type, and expression of the hazard. If possible, identifying and removing these hazards early can extend the life of your asphalt and help keep your insurance premiums down as well.

8. Traffic Control is Important.

Older and graying pavements make it significantly more difficult to see the traffic markings. This can lead to potential hazardous situations. Often the markings, arrows, crosswalks, stops and bars can become unrecognizable because of “ghosting”. This is the prior striping bleeding into view and confusing the drivers and pedestrians and leading to potential accidents. This condition is usually timely with the need to seal coat the pavement. Seal coat and restripe will solve this for years to come. This will also allow the property to be brought up to the current Building Code.

9.  Time is Not on Your Side.

By the time most people notice a problem with their paving, the damage could be far more extensive than even a detailed site walk can really pinpoint. Frequent examination and correcting areas which show indications of failure as soon as possible after they’re noted can help prevent costly, time-consuming, and unnecessary repairs.

 

10.  Call in the Professionals.

A paving job done poorly can often be worse than no repair at all. That’s why it’s worth your while to bring in pavement professionals with a solid track record of proven results. Calvac Paving has been serving the Bay Area since 1974, and we have the experience, resources and personnel to do the job right the first time, every time.

The educational articles not only describe what each service entails, but when it is typically needed. This can help business owners, commercial property managers, homeowners association managers and many other clients to educate themselves and their clients about what work is needed at their properties.

For example, the article about asphalt repair explains that interconnecting cracks called “alligatoring” are typically found in high traffic areas or near dumpster enclosures.

“In the areas of the pavement surface where failure is showing (areas of ‘alligatoring’) we may propose removal of the failed asphalt and replacement with a thicker cross-section of newly placed and compacted asphalt,” the article noted, adding that Calvac Paving will mill, saw cut or jackhammer the perimeter of the failed areas.

“It is recommended that the new ‘patch’ be placed at a minimum thickness of 1-1/2 times the original asphalt depth to bridge any inherent weakness in the base material in that area.”

Calvac Paving Continues To Maintain A High Safety Work Record

Calvac Paving

In 2015, we reported Calvac Paving has maintained a high degree of safety, as measured by reduction adjustment to our worker’s compensation insurance premiums. These numbers are released annually, which means we just received the latest figures on our performance. The 2018 California Experience Modification ratings for workers’ compensation insurance have now been released, and once again Calvac Paving is proud to be an industry leader in workplace safety! 

IMG_6064

Calvac Paving’s rating of 76 is well below the industry standard and means that we pay nearly 25% less than what many of our competitors pay for identical workers’ compensation coverage. This means we have had more than 25% fewer incidents and lost working hours than industry actuaries would anticipate for our line of work. Obviously, this is better for our employees and the company as a whole, because it means our training programs and safety protocols are working, and of course, the financial benefits are welcome as well. However, this means a lot more than just a bump in the bottom line to us at Calvac Paving. 

 

An Ex-Mod score of 100 is considered “average,” while an Ex-Mod of 125 would be “high-risk.” Employers with an Ex-Mod of 100 pay the full premium for their worker’s compensation insurance, while a high-risk employer would pay the full premium plus 25%. This metric means our employees are more likely to practice sound safety on the jobsite, while in transit and at the yard, increasing the odds they will all get home to their loved ones in the same condition they left for work. This, in turn, allows clients to accept our job bids with confidence that they will receive consistently excellent work, produced with safety uppermost in mind at all times.

 

 

Calvac’s safety program includes:

  • Up-to-date training on the latest OSHA and DOSH policies, procedures and protocols
  • First aid training including CPR
  • Hazard identification and mitigation
  • Workplace and job site safety and loss prevention
  • IIPP and Early Return to Work programs which allow injured employees to return to work on modified duty while remaining in compliance with healthcare provider recommendations and directives

Our insurance brokers have stated in the past that Calvac’s safety initiatives have been so successful, we are setting the standard for how safety training and associated loss prevention ought to be carried out. As we take a great deal of pride in being the benchmark for excellence in every facet of our operations, this is always welcome feedback.

The principals and management of Calvac Paving are very proud to once more be able to prove we are among the best in the construction industry at what we do. Our emphasis on proactive safety training and implementation means our employees have more productive days with a lower risk of injury, allowing them to perform at their best at work and in their personal lives. We are also pleased that our clients get to reap the benefits of our training in terms of increased production and reasonable budgets, with less potential for damaging incidents.

Construction is not an easy field in which to balance safety with productivity. However, we at Calvac are proud to show it’s not just possible; for us, it’s just the way we do our jobs, every time, every day. We look forward to continuing to prove our commitment to safety and a task done well for many years to come, working to keep our employees, clients and the general public safe as we go.

Los Altos New Private Road Project

los altos new road repair

Calvac Paving was proud to be able to serve the city of Los Altos, California by replacing a  common private road within the community. The roadway needed repair for durability, safety and aesthetic reasons, giving Calvac Paving the opportunity to once again demonstrate the quality and attention to detail of our work.

This project required some delicate handling because, as a private road in a residential area, Calvac Paving had to be mindful of residents’ access needs as well as the possibility of fires or other emergencies. It also necessitated using a special process that allowed for minimum road closure time and maximum performance. We created a short video to show the highlights of the paving process, from top to bottom.

The process Calvac Paving decided to use was a “petromat” overlay on top of the existing roadway. To do this, the failed areas were prepatched using full depth hot mix asphalt. Once this was done, the existing utility boxes in the roadway were raised up, so as to secure them against further failures in the subgrade or roadway itself. An asphalt binder and paving fabric were installed next, allowing the existing road surface to bond properly to the hotmix upon placement. A 2” lift of hotmix was placed using a self-propelled paver, and then the lift was compacted to produce a smooth, level road surface.

The finished product is much nicer-looking, offers more flexibility and durability, and didn’t require as much disruption of local traffic patterns as more traditional repair and rehabilitation projects. Calvac Paving specializes in these kinds of jobs, where tight traffic constraints and the need for access make conventional processes difficult or impossible. In this particular case, we left the property owners with a smoother, more aesthetically pleasing, better-driving roadway.

Calvac Paving has been serving the Bay Area since 1974, providing the highest-quality paving, concrete and earthwork solutions for residential, commercial, transportation and public applications. From annual budgeted concrete repairs, asphalt paving and seal coat to a complete new roadway build and striping services, Calvac Paving has the equipment, knowledge and experience to deliver excellent quality at competitive prices. We approach every job with a can-do attitude and consider carefully how to proceed to obtain the best balance of cost effectiveness, performance and safety.

 

Because our President, Jim Adam, carries CASp certification, Calvac Paving is also an ADA-certified company. This means we are continuously keeping abreast of new developments and adaptations to ADA regulatory requirements and standards. Carrying this prestigious and important certification allows us to ensure every project we undertake is in full compliance with ADA Standards as well as the California Building Code, which in some cases are even more stringent.

In addition to our certifications and awards, Calvac Paving offers a three-year warranty to qualifying customers, three times the industry standard. We stand behind every job we do with strict quality and performance standards, because we want our clients to have peace of mind that the work they get from Calvac Paving will be the best anyone, anywhere can deliver. We hold our work to the highest possible standards for materials, workmanship and durability, Calvac Paving can take pride in giving our clients/Stakeholders a finished product they can trust.

Calvac Paving is proud to have served the Bay Area as long as we have, and we will continue to do so in 2016 and beyond. Whether we’re fixing a private roadway in Los Altos or working on a major airport runway renovation, striping a parking lot or building an access ramp to the exacting tolerances of ADAS and CBC requirements, we are passionate about our work and proud of the final result.
