Embodiment Construction

[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts all involve the protection scope of the present invention.

[0047] like Figure 1 to Figure 5 As shown, the present embodiment proposes a road surface crack treatment method,

[0048] Including, step 1, cleaning up impurities in cracks;

[0049] Step 2: Inject sealant into the cracks, and then lay several layers of fillers into the cracks. The first layer is 1 / 4 thickness of gravel chips, the second layer is 1 / 4 thickness of asphalt, and the third layer is 1 / 4 thickness. / 4 thickness of gravel chips, the fourth layer is 1 / 4 thickn...

Abstract

The invention relates to the technical field of road repair, and provides a pavement crack treatment method. The method comprises the following steps: 1, cleaning impurities of cracks; 2, injecting joint filling glue into the cracks, and laying a plurality of layers of filler in the cracks, wherein the first layer is gravel chips with the thickness being 1 / 4, the second layer is asphalt with the thickness being 1 / 4, the third layer is gravel chips with the thickness being 1 / 4, the fourth layer is asphalt with the thickness being 1 / 4, and the asphalt of the fourth layer exceeds the height of the pavement by 3-5 cm; 3, using a repairing machine to heat the repaired position of the crack; 4, vibrating the repaired position of the crack by using a repairing machine; 5, polishing the repaired part of the crack by using a repairing machine. By means of the technical scheme, the problem that in the prior art, bonding is not firm due to a groove body cutting and crack pouring method is solved.

Description

technical field [0001] The invention relates to the technical field of road restoration, in particular to a method for treating road surface cracks. Background technique [0002] Existing pavement crack treatment generally uses a cutting machine to clean the groove after expanding the gap, then preheats the groove, and pours repair materials. This traditional method requires the use of equipment such as cutting machines, dust removers, and seam filling machines, which consumes a lot of tools and manpower, has low efficiency, produces more solid waste, and causes dust pollution in the surrounding environment. In addition, due to cutting The surface of the tank body is relatively flat, and the bonding area with the repair material is not large, resulting in weak bonding of the repair material and easy separation from the tank body, which affects the repair effect. Contents of the invention [0003] The invention proposes a method for treating cracks on the pavement, which s...
