Patent ID: 7503724

Claim:
A method for bonding a layer of asphalt pavement material comprising asphalt material to a substrate pavement layer comprising paving material, the paving material selected from the group consisting of asphalt material, soil, clay, sand, shell, cement, limestone, fly ash and mixtures thereof, the method comprising: providing an emulsified composition which includes at least a first phase of an asphalt composition, a second phase of water, emulsifier and a stabilizer, the asphalt composition selected to provide a coating having a penetration value less than about 20 dmm and a softening point greater than about 140° F. (60° C.) when applied to the substrate pavement layer and cured; applying the emulsified composition which includes the first phase of asphalt composition, and the second phase of water, emulsifier and stabilizer to an exposed surface of the substrate pavement layer at a rate sufficient to provide an exposed coating on the exposed substrate surface, the emulsified composition having an amount of the asphalt composition effective to bond the layer of asphalt pavement material to the substrate pavement layer; heating the asphalt pavement material to provide a heated pavement material to a temperature sufficient to soften the coating an amount effective to form a bonding surface on the exposed coating; and applying the heated asphalt pavement material to the exposed coating to form a pavement layer and to soften the exposed coating forming a bond between the pavement layer and the substrate pavement layer.
