Problems solved by technology

After the asphalt road is used for a period of time, the road surface is prone to gaps, and the gaps on the road surface need to be filled and repaired. During the construction process, the damaged aged asphalt in the road surface is generally removed, and then filled with asphalt raw materials, but the aging cannot be repaired. of asphalt is reused, seriously depleting resources
Furthermore, in previous pavement repair operations, asphalt raw materials were generally applied manually, which easily caused the asphalt to change from a fluid state to a viscous state, affecting the repair effect

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0028] Such as Figure 1 to Figure 3 As shown, the invention provides a kind of asphalt pavement construction method, comprising:

[0029] Step 1. Clean the gaps in the asphalt pavement to be repaired;

[0030] Step 2. Heating the asphalt pavement to be repaired that has been cleaned in step 1, and then cutting and crushing the gaps on the asphalt pavement to be repaired. While cutting and crushing, add asphalt regeneration agent to the gaps to restore the crushed asphalt to fill the gap;

[0031] Step 3. After the crushing work in step 2 is completed, continue to add asphalt repair agent to the gap, and further fill the gap of the asphalt pavement to be repaired;

[0032] Step 4: After the asphalt repair agent is filled in the gap in step 3, the repaired road surface is r...

Abstract

The invention discloses an asphalt pavement construction method. The method comprises the steps of 1, performing clean treatment on a gap of an asphalt pavement to be repaired; 2, heating the asphaltpavement to be repaired obtained after clean treatment is completed in step 1, then, performing cutting and breaking on the gap of the asphalt pavement to be repaired to form a repair space, adding anasphalt reclaiming agent to the repair space while cutting and breaking are performed, and reducing the smashed asphalt to fill the gap; 3, after breaking work in step 2 is completed, continuing to add an asphalt repair agent into the gap, and further filling the gap of the asphalt pavement to be repaired; 4, after the gap in step 3 is filled with the asphalt repair agent, grinding the repaired pavement through a road roller, and then, paving the ground pavement with a composite fiber cloth. Aged asphalt can be recycled, and resources are saved; in addition, the pavement repair effect in construction operation is effectively improved.

Description

technical field [0001] The invention relates to the field of road construction, in particular to an asphalt pavement construction method. Background technique [0002] At present, most of the roads built in our country are asphalt roads. After the asphalt road has been used for a period of time, the road surface is prone to gaps, and the gaps on the road surface need to be filled and repaired. During the construction process, the damaged aged asphalt in the road surface is generally removed, and then filled with asphalt raw materials, but the aging cannot be repaired. The asphalt is reused, seriously depleting resources. Furthermore, in previous pavement repair operations, asphalt raw materials were generally applied manually, which easily caused the asphalt to change from a fluid state to a viscous state, affecting the repair effect. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide ...
