When a pavement system is close to the end of its life cycle, the existing surface should be over layed with a new layer of asphalt to extend its wear life. However, care must be taken to address all cracked areas in order to prevent translation of cracks through the new surface. All broken areas that move under the weight of a loaded truck must be repaired with full depth asphalt. Isolated cracks must be sealed with a hot pour crack sealer to retard reflective cracking.
· Excavate and repair cracked areas using full depth asphalt. No surface mix is required, just binder asphalt.
· Completely clean surface of all vegetation and dirt with a broom tractor and forced air blowers. Install riser rings, if needed.
· Mill the transition areas and perimeter of lot to a depth and width sufficient to provide proper drainage of new surface. Mill around existing utility manholes, if needed.
· Apply a liquid asphalt emulsion to old asphalt to bond the new layer (at least 0.05 gallons per square yard).
· Install asphalt surfaces
