  Causes of Asphalt Surface Deterioration:
The most common causes of asphalt deterioration are water accumulation in areas of lower elevation, excessive loads on the asphalt, and the destructive effects of vehicle oil and gasoline. Over time, water accumulation can cause asphalt to crack and split severely, or "alligator" as it is commonly referred to in the paving industry. Bearing excessive weight can cause the asphalt to sink, and oil and gasoline that seep into the asphalt cause further deterioration.

Asphalt Patching Methods: When areas of pavement deteriorate and need to be repaired, Mason Pavement Marking corrects the problem by using one of two methods:

Skin Patching is recommended when the underlying base is structurally sound and is typically used on depressed surfaces. This process is accomplished by cleaning the existing pavement, applying a tack coat (asphalt-based glue), and applying hot-mixed asphalt. The new asphalt is then mechanically compacted. Because the skin patches are placed on top of existing pavement, the finished surface may be slightly higher. The edges are blended in, or "feathered," as much as possible.

Removal and Replacement, or R&R, is used for more severe deterioration, especially when the underlying base has been affected. The damaged areas are squared off, saw cut, and excavated to a depth from two inches to two feet depending on the subsurface conditions. New aggregate is then added, if required, and compacted in preparation for the new asphalt surface. Finally, hot-mixed asphalt is placed over this layer and compacted. Any raveled surfaces (surfaces in which the aggregate is coming loose) are then smoothed out and re-striping can be done, if needed. Mason Pavement Marking also recommends treating the entire surface with a seal coat to restore the original look of the area and further protect it.

Benefits of Asphalt Patching:
Both Skin Patching and Removal and Replacement are economical components of an overall pavement maintenance program. One benefit of timely asphalt patching is the prevention of more expensive repairs in the future. Also, creating a safer environment results in fewer accidents and, ultimately, reduced ownership liability.

Asphalt Sealing:
In conjunction with hot grout crack sealing, asphalt sealing is the most economical way to preserve your pavement investment and keep it looking the best it can. Our Black Mac asphalt sealer actually penetrates and revitalizes your asphalt surface, retarding oxidation and brittleness. By helping to restore the binding action of the asphalt, normal deterioration is reduced and the area's lifespan extended. When prepared properly, Black Mac seals areas discolored by gas and oil stains and waterproofs the asphalt surface reducing frost damage.
