Asphalt can become damaged and require resurfacing in order to maintain its function and appearance. Damage is typically in the form of cracking which is caused by both the freeze/thaw cycle and the effects of the sun and moisture. The sun oxidizes asphalt cement, causing shrinkage and creating separations that lead to cracks. Moisture then reaches the pavement’s subsurface and softens it. Surface traffic will then deteriorate the pavement around the crack, creating a larger problem…the pothole.
There are many benefits of asphalt resurfacing:
Why Seal Asphalt Cracks?
Proper attention to cracks will prevent problems from spreading and extend the life of the pavement. Treating the problem while it is still small will prevent costly resurfacing later on.
Existing cracks are cleaned by compressed air. Cracks may also be routed to create a reservoir for additional material. This allows for greater expansion and contraction of the pavement without cracking. A hot liquid asphalt cracksealing material is then applied to the cracks, after which a squeegee is used to “band” the crack and blend the material with the existing pavement.
Caring For New Sealcoat
Once the decision has been made and the sealcoat has been applied, traffic should be kept off of the area for at least 24 hours. When parking lots must be open for customer parking, the contractor can arrange to sealcoat the lot in sections. Failure to keep cars off of the sealcoat before it dries and cures will result in tracking throughout the lot and onto the sidewalks and halls of adjacent properties.
