Asphalt reinforcement comprising asphalt emulsion-impregnated nonwoven fabric and method of repairing pavement using the same

Abstract

Provided is an asphalt reinforcement. The asphalt reinforcement includes: a reinforcing fiber layer having a plurality of holes formed therein; a film layer being breathable or non-breathable and having at least one resin selected from the group consisting of polypropylene, polyethylene, ethylene vinyl acetate, polyethylene elastomers, polypropylene elastomers, polybutene, and thermoplastic polyurethane, and has a melting point of 90° C. to 130° C.; and a nonwoven fabric layer disposed between the reinforcing fiber layer and the film layer, impregnated with an asphalt emulsion, and having a melting point of 50° C. to 130° C. The asphalt emulsion is prepared by mixing a first emulsion and a second emulsion and has a viscosity of 40 to 200 cP. The first emulsion contains modified asphalt, a curing agent, an anti-stripping agent, and petroleum resin, and the second emulsion contains latex, a fatty acid amine salt, calcium chloride, hydrochloric acid, a thickener, and water.
