Eventually routine maintenance on your driveway or parking lot will need to be supplemented with repair work. Repairing necessary areas ensures that damage will not continue to spread throughout the existing driveway, parking lot, or road. Pot holes, alligator cracking, standing areas of water, and depressions in asphalt are signs that seal coating and crack filling are no longer sufficient. Once these take place, structural problems to the sub base have occurred.
Environmental freezing and thawing cycles, oxidization due to the sun, snow plows, and general wear and tear can damage the first layer of asphalt pavement. This damage often is referred to as alligator cracking and the damage is confined to only the first layer of asphalt pavement. The base course of the asphalt and the sub base of gravel are still unaffected at this point in the life cycle of asphalt.
