The three main methods used to repair distressed asphalt surfaces including removal and replacement, patch overlays, and complete resurfacing. To determine which type of repair is most appropriate, we take the type and severity of distress into account to guarantee the most effective pavement repair. Click the following link to learn more about the types of asphalt deterioration.
While very similar to asphalt resurfacing, an asphalt overlay is performed in a patch style rather than a complete resurfacing project. A typical overlay would install 1/2" to 1 1/2" inches of new asphalt over selected areas.
A typical resurface would install 1 ½ to 2 ½ inches of new asphalt over all of the existing surface. The entire asphalt surface would have the same appearance it had when it was new, at a fraction of the original install cost.
When high severity alligator cracking, rutting, depressions, and edge cracking are present, asphalt removal and replacement may be the most cost-effective repair. A deteriorated area will continue to grow until treated. The deteriorated asphalt will contaminate the stone sub-base and will continue until repaired.
Common Repair Methods and Installation Techniques
Asphalt milling is commonly used when the wearing course surface asphalt has deteriorated, yet the stone sub-base shows no signs of distress. After a hydraulic milling machine removes the wearing course, asphalt is then re-installed in two "lifts"; the first leveling course lift provides a level and depression-free surface while the second is a new installation of wearing course asphalt. However, milling can also be used in smaller applications for perimeter milling prior to asphalt overlays to help ensure proper drainage as well as to create "butt joints" between transitional sections that allows resurfacing to take place without milling the entire internal area.
