Considerations For Resurfacing Asphalt Driveways And Parking Lots
Resurfacing or replacing of the material of a driveway or parking lot may be necessary after a period of time. This is quite different from sealing or other types of minor repairs. Although resurfacing will not last as long as the installation of new asphalt, it is an option that is considered by a lot of people because of financial concerns. As in most repair projects, the finished job will be determined by the level of preparation and the competence of the contractor.
In a complete tear-out, the old drive will have to be removed by the contractor. An initial layer of compacted gravel will then be applied, followed by a course of compacted asphalt base. This layer is usually about two to four inches in thickness. The final layer of compacted material will then be applied.
During the process of resurfacing, the surface course of asphalt is installed on top of the existing surface of the driveway or parking lot. The two layers will adhere together easily because they are made with the same material. It is however important to consider why the driveway is failing before you choose this option. For instance, if the problem is from a weak base, adding a new layer will not be the right solution.
Asphalt can also be installed on a concrete drive. You do have to implement certain precautions so as to ensure that the concrete does not shift under the new surface. Proper preparation will ensure that this does not happen and the drive will last for several years. There are a number of things that you have to check in order to know if the existing concrete driveway is suitable. The blocks should be level, and the joints and cracks must be close.
No matter the type of installation that you want to do, there are certain things that you have to watch for. Drainage should be taken into consideration so that rain water is carried to the street or to a catch basin. Water should not flow back into your garage or onto a neighbor's property. The contractor has to also ensure that the edges are properly supported.
It is vital to choose a competent contractor for your asphalt resurfacing project. You can evaluate the company's work by checking other driveways that they worked on a few years ago. No matter the company that you choose, make sure that a proper contract is drawn up.
