A method for repairing crack on asphalt road pavement, relates to a processing method of the cracks of asphalt road. The repair method includes the following steps: a. cleaning the crack surface, and clearing away the dust attached on the slit surface, and so on; b. cracks are carried out a reperfussion and a filling-up handling with the asphalt glue, or carried out a pasting handling by inserting a sealing strip with the major components of asphalt on the crack surface; c. using an asphalt recovery agent with the main ingredients of the asphalt and the coal tar to brush around the asphalt glue and the sealing strip. The invention can form an effective sealing layer around the cracks to prevent the water damage.
Description
Repair method of asphalt road pavement crack technical field The invention relates to a treatment method for asphalt road pavement cracks. Background technique 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. 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.
