Description

Technical Field

[0001] The utility model relates to the technical field of asphalt pavement crack repairing, and more specifically to a device capable of quickly repairing asphalt pavement cracks. Background Art

[0002] After the highway is put into use, cracks will appear on the asphalt pavement due to various factors. Although the initial formation of cracks on the pavement has little effect on the use function of the pavement, due to the large volume of traffic on the highway and the high speed, if they are not filled in time, it will affect driving safety. In addition, the expansion of cracks on the pavement will gradually weaken the bearing capacity of the road structure. Therefore, timely filling of cracks on the pavement is extremely important to extend the service life of the pavement. At present, the commonly used asphalt pavement filling process is slotting and filling. Slotting and filling is to use asphalt to fill and seal the cracks in the pavement after slotting. The process method is generally to use machinery, such as slotting machines, to forcibly cut the cracks in the pavement, so that the cracks in the pavement are widened and deepened, and then fill the cracks in the pavement with asphalt to fill and seal them.

[0003] However, when pouring asphalt into the cracks after grooving, since the asphalt is relatively viscous and has low fluidity, there is a hollowing phenomenon inside the crack groove after pouring and smoothing, and the entire crack cannot be truly filled. In addition, since the inner wall of the crack groove is irregular and there are many small gaps, the bonding force between the asphalt and the side walls on both sides of the crack is limited. In addition, a special grooving machine is required when grooving the cracks, and the construction operation process requires the use of a variety of tools, and the construction time is long. Construction on highways will affect the traffic efficiency of passing vehicles. In order to repair cracks in asphalt pavement, it is necessary to groove the cracks and pour asphalt.
