A road repair method is provided to prevent a road form damaging again while repairing a road and to shorten the time required for repairing a road by injecting grout materials for reinforcement and grout materials for repair. The road repair method for repairing a road more effectively comprises the steps of forming a primary injection hole to penetrate one side of a road(30), inserting an injection pipe to the primary injection hole and injecting reinforcing grout materials(40) to the inside of a rubble layer(20) through the injection pipe at a pressure of 20kgW/cm^2, forming a secondary injection hole(H2) to penetrate one side of the road and the rubble layer in order, inserting an injection pipe to the secondary injection hole to make the front end of the injection pipe located between the rubble layer and the ground(10), injecting filling grout materials between the rubble layer and the ground through the injection pipe at a pressure of 100kgW/cm^2 and removing the injection pipe from the secondary injection hole, and then sealing up the secondary injection hole. |
