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

An asphalt reinforcement comprising:

• a reinforcing fiber layer having a plurality of holes formed therein;
• a film layer, which is breathable or non-breathable, comprises 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, which is disposed between the reinforcing fiber layer and the film layer, is impregnated with an asphalt emulsion, and has a melting point of 50° C. to 130° C.,
• wherein the asphalt emulsion is prepared by mixing a first emulsion and a second emulsion and has a viscosity of 40 to 200 cP, wherein 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.
