ROAD REPAIRING METHOD USING COMPOSITION OF ROAD REPAIRS

摘要

The present invention relates to a concrete pavement road repairing method. As a means for solving the problem, the present invention comprises: a road surface crushing step (S1) for crushing the damaged portion of a concrete pavement road with a crusher so as to form a repair groove of predetermined width and depth; a road surface cutting step (S2) for cutting a cut groove by cutting the periphery of the repair groove in such a manner that the bottom surface and the cut surface become perpendicular to each other by using a cutting machine; a road surface chipping step (S3) for chipping the inside portion of the repair groove with respect to the cut groove by using a hammer drill; a cleaning step (S4) for cleaning the repair groove while removing the chipped concrete remaining by using high pressure water; a placing step (S5) for placing a road repair composition onto the repair groove; and a curing step (S7) for leaving the placed road repair composition for a predetermined time until the composition becomes cured. As the road is repaired using the road repair composition as above, the materials purchase and the construction become very simple in comparison with the existing construction methods. In addition, the damaged portion of a concrete pavement road can be recovered with speed using the expansion force of expansion type concrete such that the generation of defects (for example, the generation of gaps due to retraction) becomes very few. Further, the traffic delay and traffic congestion due to the vehicle control and road control can be reduced and the convenience of drivers can be promoted owing to the fast curing speed. Therefore, the construction can be sufficiently implemented at relatively low costs in comparison with the existing construction methods.
