Abstract
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.
