It is very important to understand the I-5 top course asphalt that is in your driveway or parkinglots. The strength of your asphalt is directy related to the gravel base that lies under your driveway or parkinglot. Most people who are looking at the asphalt dont understand that there is a lot more involved than just the serface they are looking at. The surface that the customer is actually looking at is just the top part of a few layers. It is almost like imaging a three layered cake consiting of dirt, stone and blacktop for the icing.
In New Jersey the layers consist of a bank run at the very bottom of your driveway. Than over the top of the bank run is your stone base. After that the asphalt is than layed and compacted on top.The stone base is what really handles all of the presure from cars, suvs and delivery trucks. Keeping this stone base dry is what will keep your driveway or parkinglot intact. The only way to keep this stone dry is to apply some sort of sealer to stop the water for penatrating through the asphalt. Asphalt is pourous and will let some water through the problem with that in New Jersey is the cold months. In the cold this water will expand and contract under the asphalt and cause all different kinds of issues.
In the sealcoating industry there are atwo maintypes of sealcoating products available. The first is coal tar sealcoat, this sealer has different chemicals in it that do not allow the destructive elements of weather and chemicals to effect its propertys. So it acts like a barrier over the blacktop to protect it. The next type of sealer is a oil based sealer, this sealer is a little diferent because of the way it soaks into the asphalt. It doesnt provide a barrier over the blacktop like coaltar sealer. But it soaks into the blacktops poursand isknown for the flexabilty it gives the asphalt.anyof these two is better than nothing at all.http://keatorbuiltpavingandsealcoating.com
