Claim:
A composition of petroleum asphalt modified synthetic asphalt recycled tire rubber emulsion which may be used as a crackfiller for asphalt and portland cement pavements, as a roof coating, as a sealcoat for asphalt pavement parking lots, and to prepare slurry seal coatings for asphalt pavements, the composition comprising: a first mixture of petroleum asphalt modified synthetic asphalt comprising 84% to 90% by weight petroleum asphalt, 1% to 12% by weight gilsonite or man-made asphaltene residium, and 1% to 12% by weight tall oil product, the first mixture at between 135° C. (275° F.) to 176.7° C. (325° F.) combined with high shear into a second mixture; the second mixture comprising 87% to 93% by weight water, 0.1% to 0.5% by weight aluminum chloride, 1% to 6% by weight nonylphenol surfactant, and 3% to 6% by weight bentonite clay, at 4.4° C. (40° F.) to 37.8° C. (100° F.) with a pH of 4 to 6.5; wherein the first mixture when added and mixed with high shear into the second mixture results in an emulsion, wherein 4% to 7% by weight granulated minus 10 mesh to minus 80 mesh recycled tire rubber, and 1% to 5% by weight cationic polymer latex are added results in a final emulsion comprising 45% to 50% by weight water, 0.1% to 0.3% by weight aluminum chloride, 1% to 4% by weight nonylphenol surfactant, 1% to 3% by weight bentonite clay, 1% to 5% by weight cationic polymer latex, 32% to 40% by weight petroleum asphalt, 0.4% to 5% by weight gilsonite or man-made asphaltene residium, 0.4% to 5% by weight tall oil product, and 3% to 10% by weight granulated minus 10 mesh to minus 80 mesh recycled tire rubber, at temperatures between 60° C. (140° F.) to 98.9° C. (210° F.).
