Abstract:
1. A composition of a modified petroleum asphalt-granulated recycled tire rubber emulsion which may be used as a cold applied crack filler for Portland cement and asphalt pavements, as a cold applied roof coating, as a seal coat for asphalt pavement, and as a slurry seal coating for asphalt pavement, the composition comprising: a first mixture of 45 to 65 percent by weight petroleum asphalt, 10 to 20 percent by weight recycled and re-refined motor oil flux, 1 to 25 percent by weight mineral filler comprised of a mixture of iron oxide, iron sulfide, iron, carbon, and magnesium iron silicate, and 5 to 20 percent by weight minus 10 mesh to minus 80 mesh granulated recycled tire rubber; a second mixture comprising 90 to 94 percent by weight water, 0.01 to 1.0 percent by weight caustic soda, 2 to 7 percent by weight bentonite clay, and 0.1 to 4 percent by weight nonylphenol surfactant, the first mixture added to the second resulting in a final emulsion comprised of 40 to 60 percent by weight water, 0.01 to 0.05 percent by weight caustic soda, 1 to 4 percent by weight bentonite clay, 1 to 3 percent by weight nonylphenol surfactant, 20 to 30 percent by weight petroleum asphalt, 3 to 10 percent by weight recycled and re-refined motor oil flux, 1 to 10 percent by weight mineral filler comprised of a mixture of iron oxide, iron sulfide, iron, carbon, and magnesium iron silicate, 1 to 5 percent by weight minus 10 mesh to minus 80 mesh granulated recycled tire rubber, and 1 to 10 percent by weight anionic polymer latex.
