Asphalt paving is actually a generic term used to define the application of asphalt on a paved parking lot or driveway surface. The term is used as a synonym for interlocking paving, which is the more common type of paving that is utilized on residential streets and highways. The asphalt pavementing is applied in several layers to create a durable and visually appealing surface. The asphalt pavements are then cured and colored to provide a non-slip surface.Checkout Lewisville asphalt paving for more info.
When asphalt paving occurs on a paved driveway, the asphalt surfaces are first prepared by an application of what is known as a trowel, which is basically a thick layer of gravel. The gravel is then poured onto the asphalt pavements to form a sturdy base for the paving that is then enhanced with various chemical compounds that will aid in the structuring of the asphalt pavements. Various drainage features such as crevices, depressions and what are known as scalloped depressions are also applied to the asphalt paving to assist in the proper drainage of water and moisture that can collect on the asphalt surfaces as they are driven over. Once the asphalt paving is properly assembled and all the necessary drainage features have been applied, a thick layer of what is called a “dry stone” is then laid on top of the paved area to act as the color layer and as the backing for the decorative asphalt pavers that will be installed in a few weeks. A proof roller is then used during the installation to smooth out any bubbles or scratches that may exist on the asphalt surfaces before the concrete is poured onto the concrete base.
Cracking is typically used as a last step before the asphalt paving project is completed. If a small crack does not stop the flow of traffic then the contractor may decide to “crack” the area and repair it prior to the pour of the concrete. The crack may not pose a problem to drivers, but if a larger pothole occurs then it could significantly decrease the efficiency of traffic on the roadway. Potholes that occur at the base of the paved area are typically more difficult to fix, but in some instances the contractor may choose to repair these larger cracks prior to pouring the concrete so that they do not become a problem once the asphalt potholes have started to settle.
