Asphalt Paving Green Bay, Appleton, Oshkosh.
Many driveways and parking lots we do already have their own gravel. If so, we will grade it and then put down either one or two layers. As long as the rock quarry where we get our gravel from has big rock, we will start with the bigger rock always. Whether it is a driveway or parking lot. When we start fresh in putting gravel over dirt, we use big rock because it makes for a better job. Then we put on the top layer, the finish matte which is a finer material. Whenever we lay it through the paver it becomes smoother. If a job calls for two or more layers, the first layer is that binder or base coat. The rock is big and rough, especially for a lady, if she walks on high heels it is hard to walk on because the rocks are so big. There is nothing to smooth things out. The top layer or finish coat is a finer smoother material. We use that the same on parking lots and driveways; residential and commercial. And if for a residential job we only put down one layer we use the top coat on the base.
Reinstall or Overlay
Sometimes, on older driveways, we have to install the pavement all over again. We had to redo driveways that were 20 years old, and we had to redo driveways that were 40 years old. How long your blacktop lasts depends mostly on the base work. Sometimes we do an overlay over top of the old asphalt. But if the base underneath the blacktop is bad, I don’t recommend it. What I recommend is to take the old blacktop out and to address what is wrong with the base. Over the years, clay can come up through the gravel and make soft spots in the base. We dig those soft spots out and then do base again. On some jobs you can do overlays, on some you can’t. We have to look at how bad the blacktop is before we make that decision.
There is one product that can be applied as soon as we are done paving. It is a fog coat or fog seal. Fog seal is a thin material with a hardener in it. It gives a good head start to the driveway or parking lot asphalt. It cures as well as adds a little bit more oil to the blacktop. On some jobs we are asked to apply fog seal. If so, we either apply it that same day or one or two days after paving and rolling in the driveway or parking lot. Fog seal is not necessarily included. Some people choose to apply it and some don’t. Unless specified in the beginning of the contract, it is not included. Fog sealing is an extra service if the customer wants to take real good care right off the bat. It is the same as with buying a new car. They will try to sell you a sealant as soon as you leave the car dealership. Instead of waiting a year to put a seal coat on, the dealership will offer you a special commercial rate sealant. So that, as soon as you leave your brand new car will be protected.
