1. the repairing groove with the depth larger than the pavement crack depth and the repairing material filled in the repairing groove are arranged, so that the repairing is not limited to a damaged surface layer, meanwhile, the pavement base layer is repaired, the repairing effect is improved, and therefore the condition that secondary cracking occurs on the repaired pavement is reduced.

2. The purpose of the expansion screw is to enhance the tensile strength of the repair material and the pavement and to improve the durability of the pavement after repair.

3. The purpose of arranging the silicone sealant is to prevent rainwater from entering joints among all pavement blocks and reduce rainwater erosion damage to the pavement.
