In particular, we disclose improvements in the formulations of asphalt aggregate wear surfaces, substrate layers and interface layers between the substrate and wear surfaces. In one embodiment we also employ an unsaturated monomer or an unsaturated elastomer.
Claims1
A method of repairing a crack in a substrate concrete layer of a road pavement comprising filling the crack with a composition composed of rubberized asphalt and 0.5 to 10% glass flake and applying a thin layer approximately 1/16 inch of glass flake over the upper surface of the substrate layer adjacent the crack and over the said composition to provide a multi-layer thickness of slip plane for movement of overlying courses of the pavement.
