Repair method of road surface cracks
The invention discloses a repair method of road surface cracks and relates to the technical field of highway maintenance. The method comprises the following steps of a, preparing crack filling slurry by adopting the raw materials in parts by weight: 30-50 parts of low-heat cement, 25-35 parts of asphalt, 50-70 parts of sand, 40-50 parts of soil, 15-27 parts of water reducing agent and 60-75 parts of water; b, pouring the crack filling slurry into the cracks, and performing compaction through a roller to form repair pieces smoothly connected with the original road surface; and c, sticking crack pasting tapes onto the joints of the original road surface and the repair pieces. The repair method is used for handling the large cracks of the road surface, and compared with the prior art, the problem that the repair pieces are easily separated from the original road surface when the original road surface is subjected to crack pouring is solved.
