Asphalt patching is the most cost-effective way to protect your asphalt surface and foundation. By repairing potholes you get an instant improvement in looks and safety while protecting against further damage and erosion to your pavement. 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.
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.
Full-depth patching is the removal of the entire pavement surface layer, regardless of its thickness, over the patching area. Deep patching is the removal of four inches or more of the pavement surface course. Full-depth patching applies to either asphalt or concrete pavements, but deep patching applies only to asphalt pavements.
Surface patches are usually temporary patches. They are constructed by milling a portion of the pavement to a depth that removes all deteriorated material. The patch area should be milled to a minimum depth of at least three times the nominal maximum size of the aggregate used in the patch. Using a 3/8 inch size aggregate or ¼ inch size aggregate will minimize the necessary milling depth, help tie the patch to the existing pavement, and provide adequate hot mix thickness to reduce the possibility of raveling.
