ABSTRACT:
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.
