As asphalt ages, it will require repairs to maximize the life of the remaining pavement.
Patching dangerous potholes, sunken catch basins, broken, heaved, or alligatored areas is essential to the maintenance of your pavement. The type of patching is determined by the cause of the failure and the service it is intended to provide.
