Difference Between Asphalt & Concrete – Basics & Typical Uses

Difference Between Asphalt & Concrete – Basics & Typical Uses

When dealing with pavement maintenance, there are two types of pavement that you probably already recognize as asphalt and concrete.

Believe it or not, these two types of pavement are more similar than you might think, and I am not talking about how they are both flat and you can drive on them, etc… That’s a given.  What I mean is that they both consist of roughly the same materials, with the differentiating factor being the binding agent.

Let’s break it down…  First we will take a look at asphalt.

Asphalt Sample

Asphalt Sample

Asphalt Cement Concrete (Commonly called asphalt) is made up of:
– Sand
– Rock
– Liquid Asphalt Asphalt Cement (Manufactured from Crude Oil)

Now let’s take a look at concrete.

Concrete Sample

Concrete Sample

Portland Cement Concrete (Commonly called concrete) is made up of:
– Sand
– Rock
– Portland Cement (Manufactured from Lime Stone)

As you can see in the closeup pictures, both samples contain sand and bits of rock with the difference being the binder.

Both asphalt and concrete have their strengths and weaknesses, and which one you choose to go with will be determined largely by the way that you plan to use it.

Typical Uses for Concrete Pavement
– Bridges
– Dumpster Slabs
– Airport Runways
– Streets & Highways
– Small Residential Driveways

Typical Uses for Asphalt Pavement
– Parking Lots
– Playgrounds
– Airport Taxiways
– Streets & Highways
– Large Driveways

DRYCO Green Practices

DRYCO Green Practices

The industry leader in recycling.

 DRYCO Construction, Inc. is big on recycling jobs. Whether for a patch repair or a total reconstruction job, we have taken the challenge to help our environment in every way possible. By becoming one of the leading recyclers of asphalt and concrete in the Bay Area, we’ve extended our commitment to earth-friendly practices to each of our customers.

 Our recycling process begins with high-powered crushers, screens, and conveyors that turn would-be landfill into usable building materials. The end product is a strong, long-lasting, coarse material that is tested and rated as class #2 base rock. We grind up all of the asphalt and concrete that comes off our jobs and reuse it for future projects.

 We also use other by-products, resulting in less haul-off and landfill refuse. Crews separate wood and metal from job site debris and place it in specified dumpsters for recycling at our facility. Many times, excess material like grindings can be reused on-site or moved to other sites to be used as sub-base material on DRYCO jobs.

 Soil is another material that we reuse as part of our Go Green approach. When a project has earthwork that requires us to haul off soil, we take it to our recycle yard and screen it into a usable sub-base material. We stockpile any soil with integrated organic material, allow it to decompose, and then use it as topsoil for landscaping purposes.

 DRYCO is always thinking of our environment when bidding asphalt paving and concrete repair jobs. We are the industry leaders in recycling and the only pavement maintenance company in the Bay Area that has its own in-house recycle facility.

 Bottom line: when you contract with DRYCO you are not only choosing the best, you’re choosing the greenest!

Spray On Seal Coat

The Two Golden Rules When Seal Coating
There are two rules to follow when you seal coat your asphalt. Always request two seal coats, and insist that the second coat is sprayed on, not squeegeed.Seal Coat Pavement Maintenance

So Why Two Coats?
You get more for your buck… literally.  The main cost of a seal coat isn’t the material but rather the mobilization and cleaning required to coat your asphalt. And by cleaning your asphalt it needs to be clean and spotless. The “just wiped off on your pants and it’s clean” won’t cut it here. It needs to be “drop a piece of toast jam side down on the asphalt and pick it up and eat it without even hesitating” clean…

So once the asphalt is cleaned, the crews are set, and the barricades are in place all the expensive parts of the project are done. Since everything is taken care of, the cost to add another seal coat is just pennies more per sq ft. Once you compare the total cost of the two you’ll see the price is not that much more. The benefit to the second seal coat is that the coat will last longer and provide a great finished look, as long as the second coat is sprayed…

Why Spray The Second Coat?
Spray On Seal Coat
The spray on seal coat is the newest tool for a pavement maintenance contractor; however, not every contractor offers this option. Not because they don’t recommend it but because their equipment can’t spray it. A lot of the machines clog and break due to the sand and other aggregates that are in the sealer. However some contractors have been able to modify their equipment like DRYCO and can now spray on the second seal coat without altering the aggregates in the sealer. After talking to property managers and comparing a spray finish to a squeegee finish the consensus is the same, the spray on seal coat is the only way to finish off a tight parking lot.

Besides Cosmetics, What Else?
One of the biggest problems with a squeegee is controlling the application rate. Because you slide the blade over the asphalt your essentially wiping away the excess sealer, which is fine for the first coat because it very porous however once the surface becomes tight that sealer does not get absorbed as quickly. Think of it as using a squeegee on your windshield. You put down the soap and as you run the squeegee over the tight glass surface all the water comes running off. So when you try to squeegee on that second seal coat, the sealer is actually running off the asphalt. The spray on seal coat fixes this problem by allowing us to control the application rate. You paid for the entire seal coat, make sure it all ends up on your asphalt.

We had an article published by APE regarding our equipment and how effective it is at spraying on a seal coat. Check it out !

When Should You Seal Coat?

Seal Coating
Pavement Maintenance is a necessity for your asphalt, and there’s no better protection then a seal coat. We recommend seal coating every 3 to 5 years depending on usage and weather, and like many other construction services there’s a season for it. The best time to seal is from April through October (summer/beginning of fall), after that it is very difficult to guarantee a quality seal coat and here’s why: A seal coat loves the heat and the long sunny days of summer. It needs the warmth of the sun to dry and cure properly. When winter arrives it brings with it shorter days and cold/wet weather. The seal coat does not have adequate time to dry and breaks apart under normal wear and tear.

At DRYCO we’ll work as long as we can guarantee DRYCO quality, whether it’s seal coating, remove and replace, or overlaying. However, the moment the cold sets in we have to double check the conditions and see if we can still provide certain services. Over the years we have found that the jobs that get sealed in December are always the first to get resealed in April. Unfortunately we cannot predict the end of the season so our best advice is to schedule the jobs as soon as possible and get as much work in before winter comes. Below is a calendar of services offered throughout the year; however, it varies depending on the weather.

Paving Season
