ABSTRACT:
A fuel resistant binder is characterized by the addition of a carrier curing agent to a modified, unmodified or emulsified asphalt material formed of a mixture of hot, cold or emulsified asphalt and carrier and activator materials. The carrier curing agent preferably is a polyurethane moisture curing solution. A cross-linking material and aggregate are also mixed with the binder to form a material suitable for patching cracks and holes in pavement and the like. The activator assists the polymer material in linking with the asphalt while the carrier prevents the formation of gel or lumps within the asphalt. The carrier curing agent resists the penetration of fuel into the binder.
