Title:
METHOD FOR REPAIRING DAMAGED PART OF EXPANSION JOINT FOR CONCRETE ROAD
Document Type and Number:
WIPO Patent Application WO/2014/209000
Kind Code:
A1
Abstract:
The present invention relates to a method for repairing a damaged part of an expansion joint for a concrete road and, more particularly to, a method for repairing a damaged part of an expansion joint for a concrete road, comprising: an epoxy mortar plastering step for filling a damaged part by plastering, with epoxy mortar, a damaged concrete part of an joint formed so as to be expanded in a concrete road; an urethane mortar filling step for filling the joint with urethane mortar; and an urethane injection step for injecting the rapid-hardening urethane into a joint of an upper part of the urethane mortar. According to this method, it is possible to reduce required construction time by excluding processes for cutting, crushing, and high-pressure-cleaning existing concrete and the like and by quickening a curing speed of a repairing material, provide excellent binding force with an existing road pavement material, obtain waterproof properties for preventing water permeation, and further improve durability even though a dynamic load of a vehicle is repetitively generated since the repaired road surfaces are connected to each other.
