Cracking Repairs
Transverse cracking
In time, most parking areas will show some cracking. These may be caused by aging, and "the shrincage of binder with age", or by some movement of the pavement and underlying material. Cracks of this type are not a serious problem if maintained properly, but allowing these cracks to overrun your pavement or concrete will lead to failed areas costing you thousands..
Repairs
Before cracks become so prevalent that cutting and patching is necessary, cracks between ΒΌ" and 1" wide can be filled or sealed with poly-fiber reinforced crackfill. First, these cracks are cleaned with blown air or grazing wheel to remove debris, grass, old failed crackfill and other substances from the crack. Then, the reinforced crackfill or sealant is applied at temperatures in excess of 375o. After the crackfill has been applied to the cracks, then Black Beauty is added to ensure proper adhesion to the pavement surface and prevention of failure due to surface temperatures and/or traffic.
NOTE: In the event of especially hot surface temperatures, crackfill has a tendency to become rubbery when driven or stepped on. As long as the material does not lift away from the pavement, this is a normal occurrence and should not be investigated further. If the material lifts, this could be Cracksealing Deficiency and should be investigated.
