The pavement patch composition of the present invention comprises a lightweight aggregate (14) and highly modified polymer asphalt binder (12). The composition is formed by heating the binder to a flowable state, mixing the flowable binder with a lightweight aggregate, and then allowing it to cool into a solid form. The pavement patch composition (10) is used to repair voids in pavement, such as pot holes, cracks and depressions. It is applied by heating solid pavement patch composition to a flowable state and applying it to the void, or on a surface in need of repair, and then allowed to cool. The resulting patch is self-adhering, strong and flexible. The formulation of the pavement patch composition may be adjusted for specific use in a cold climate, a moderate climate, a warmer climate, or for use in various traffic applications. |
