Title:
METHOD FOR RAPIDLY REPAIRING ROAD SURFACE
Document Type and Number:
WIPO Patent Application WO/2021/129409
Kind Code:
A1
Abstract:
Disclosed is a method for rapidly repairing a road surface, the method involving: a base-layer-reinforcing material being constituted of a low-shrinkage unsaturated polyester resin, a diluent, an expanding agent, an accelerator and a polymerization inhibitor; adding a curing agent and then pouring same into a base layer of the road surface where there is a damage until no more permeation can be observed; paving with chopped basalt fibers; a surface layer repair material being constituted of an acrylate monomer, an acrylic resin polymer, a silane coupling agent, Shuangfei powder, talcum powder, quartz sand, a metal hydroxide flame retardant, an accelerator, a polymerization inhibitor and chopper basalt fibers; and adding a curing agent thereto, filling up the road surface, and then curing same. This repair method can not only function to reinforce a road base, but can also repair surface layers of damaged areas such as road surface cracks, thereby achieving the dual function of base reinforcement and surface layer repair.
