Pavement distresses accumulate as asphalt pavements age and traffic pounds them. If timely maintenance isn’t performed, distresses are compounded. Cracks become potholes and potholes become craters. It is crucial to identify these areas and repair them as soon as possible.
Patching is the process of filling potholes or excavated areas in the asphalt pavement. Quick repair of potholes or other pavement disintegration helps control further deterioration and expensive repair of the pavement. Without timely patching, water can enter the subgrade and cause larger and more serious pavement failures.
A full-depth patch is considered a permanent repair, while a thin surface patch or a “Band-Aid” pothole repair is usually temporary. Full-depth patching is the removal of the entire pavement surface layer, regardless of its thickness, over the patching area.
