Preventative Parking Lot Maintenance is a solution used to prevent further deterioration of a parking lot. It is also the most cost-effective solution to maximize pavement life while minimizing risk. As soon as a pavement first shows signs of wear and tear such as raveling, transverse cracks, longitudinal cracks, or minor block cracking, it is in need of preventative maintenance. Parking lot maintenance includes corrective measures such as crack sealing, sealcoating, and asphalt patching/repair. Effective preventative maintenance is an ongoing process that needs regular monitoring to ensure that rehabilitation strategies are producing predicted results.
