Structural Maintenance is a solution used to improve structural capacity of the parking lot. This work is outside the realm of preventative maintenance. Pavement that displays severe surface raveling or large sections of alligator cracking is in need of structural improvement. Asphalt resurfacing is the most common structural repair on a parking lot. The best chance for long-term performance of resurfacing is dependent on timing of the procedure and condition of the surface (base and sub-base asphalt layers should be intact). The effectiveness of structural maintenance is also contingent upon routine preventative maintenance performed on the newly overlaid surface.
