Patent number: 6362257Abstract: The pavement patch composition of the present invention comprises a lightweight aggregate and highly modified polymer asphalt binder. 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 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.Type: GrantFiled: August 27, 1999Date of Patent: March 26, 2002Assignee: Crafco, IncorporatedInventors: James G.
