Description

technical field [0001] The invention relates to a treatment method for asphalt road pavement cracks. Background technique [0002] After the asphalt road is paved and opened to traffic for a period of time, cracks will appear on the asphalt pavement due to various reasons. If these cracks are not dealt with in time, under the action of external factors including rainwater, vehicles and other factors, the damage to the asphalt pavement will be accelerated and the service life of the asphalt pavement will be shortened. [0003] Although the prior art has multiple treatment methods for cracks, such as pouring asphalt glue into the seam, or coating asphalt glue on the seam surface, or directly pasting the seam sealing tape (sealing tape) on the seam surface, but in use After the above treatment, there are still a large number of micro-cracks and looseness around the asphalt glue or sealing tape, which can also cause water damage. Contents of the invention [0004] The object...
