Embodiment Construction
[0011] The present invention will be further described below in conjunction with the embodiments.
[0012] A construction method for sealing and repairing road cracks with anti-detachment and anti-cracking, comprising the following steps:
[0013] a. Paint the crack 1 with a solvent 2 that can fuse both dust and asphalt to eliminate the bond between the material and the crack that affects the sealing and repairing of the crack;
[0014] b. Sprinkle high-strength fibers 3 of suitable length and size on the crack surface. The longitudinal direction of most fibers should intersect with the crack direction, and overlap each other or form a network structure;
[0015] c. Fill the cracks with asphalt or polymer sizing material, or paste the tape-shaped sealing and repairing material 4, (the fibers and the sealing and repairing material are automatically bonded together), and spread suitable sand particles.
[0016] Steps b and c can be performed in reverse, that is, first pour asph...
