Asphalt maintenance is crucial to maximizing the service life of your pavement. Routine maintenance slows the deterioration of your pavement by protecting it from its “Natural Enemies,” sun, air and water. Deciding which maintenance options are right for your parking lot, roadway, or athletic court or surface can be hard, but this guide will help give you some direction.
What causes asphalt to erode?
· Water
· Sun drying, or oxidation
· Heavy traffic
Overlaying
An overlay adds a layer of new asphalt 1.5-2.5 inches thick over the existing pavement. Overlays add strength to the pavement and improve its curb appeal. Prior to the overlay, areas that need attention should be repaired first. Overlays should be placed when the pavement is in moderate condition, typically when pavements are between 8-12 years old.
