    摘要: An improved chip seal method for treating pavement with aqueous asphaltic emulsions is provided wherein the emulsion is a blend of a conventional emulsion adapted for an aqueous asphaltic emulsion is provided in which the dispersed asphaltic material is the prereacted reaction product of asphalt having a viscosity of less than about 120,000 cps (at 140.degree. F.), an acrylamide, a vinyl aromatic monomer and an elastomer.

    摘要: An improvement in pavement surface-treating methods is provided of the type wherein a slurry seal composition is applied to the pavement the composition comprising aggregate in a slow setting asphaltic emulsion. The improvement resides in combining with the slow setting asphaltic emulsion in effective breaktime decreasing amount of an emulsion containing a chemically modified asphalt which is the prereacted reaction product of an acrylamide, asphalt having a viscosity of less than 120,000 cps (at 140.degree. F.), a vinyl aromatic monomer and a rubbery polymer.
