Claims20
A polymer-modified asphalt rejuvenating emulsion comprising:
- a stable liquid dispersion containing an asphalt phase comprising an asphalt and a rejuvenating agent wherein said rejuvenating agent comprises about 2% to about 15% of the total weight of the emulsion;
- and
- an aqueous phase comprising water, an acrylic polymer or copolymer and an emulsifying agent.
A method for rejuvenating deteriorated asphalt, which method comprises:
- a) providing a polymer-modified asphalt emulsion wherein said rejuvenating agent comprises a stable liquid dispersion containing an asphalt phase which includes an asphalt and a rejuvenating agent comprising about 2% to about 15% of the total weight of the emulsion, and an aqueous phase which includes water, acrylic polymer or copolymer and an emulsifying agent;
- and
- (b) applying the asphalt emulsion to a deteriorated asphalt pavement surface.
A rejuvenated asphalt pavement comprising polymer-modified asphalt rejuvenating emulsion atop a deteriorated asphalt pavement, the rejuvenating emulsion containing a stable liquid dispersion containing an asphalt phase comprising an asphalt and a rejuvenating agent wherein said rejuvenating agent comprises about 2% to about 15% of the total weight of the emulsion, and an aqueous phase comprising water, acrylic polymer or copolymer and an emulsifying agent.
