Asphalt cracking is caused primarily by the effects of the sun and moisture. The sun oxidizes asphalt cement, causing shrinkage and creating separations which leads to cracks. Moisture is then able to reach the pavement's subsurface and soften it. Surface traffic soon begins to deteriorate the pavement around the crack, creating a larger problem, the dreaded pothole. Proper attention to cracks will prevent the problems from spreading and double the life of the pavement. Treating the problem while it is still small will pay big dividends later by delaying costly resurfacing.

Cracks should be filled with a specified crack-filler. Asphalt sealer does not act as a crack filler. The seal will split within the crack almost immediately; therefore, allowing the penetration of water beneath the asphalt. Crack filling should automatically be included in your estimate. This prolongs the life of your seal job.
