Gilsonite-asphalt emulsion composition

The gilsonite-asphalt emulsion compositions of the present invention comprise a base stock consisting of a blend of gilsonite, asphalt, and a latex or rubber. Preferably the latex used is the residue after the water has been substantially removed, the base stock then being emulsified in water with an emulsifying agent.
