The present invention relates to a repair method for repairing a damaged part of a stretch joint for a concrete road, and more specifically, epoxy mortar filling the damaged part by plastering an epoxy mortar on the concrete damaged part of the joint part formed to be stretchable on the concrete road. Plastering step, the urethane mortar filling step of filling the urethane mortar on the joint, and the urethane injection step of injecting fast-hard urethane into the joint of the upper part of the urethane mortar, characterized in that according to this method By eliminating the process of crushing, crushing, and washing with high pressure water, it can shorten the time required for construction by speeding up the curing speed of repairing materials. Road surfaces are connected to each other Even if it occurs in duplicate, durability can be further improved. |
