Problems solved by technology

Due to the large fluidity of the mortar, the enclosure effect is not ideal, and the adjacent road surface is easily polluted. If the brush stays in the grouting area for a short time, it will not be able to form a certain liquid level, resulting in insufficient grout perfusion, which will affect the infusion composite Pavement Appearance and Construction Quality

Embodiment 1

[0020] figure 1 It is a cross-sectional view of the pavement structure during the edge sealing of the pouring composite pavement grouting construction of the present invention.

[0021] The average flatness of the adjacent asphalt pavement before construction of the poured composite pavement is 3.1mm, which is good. During the cooling process after the large-pore asphalt mixture is paved, before the grouting construction, use a forest fire blower and a broom to clean up the asphalt pavement 3 and curb 2 adjacent to the grouting area 1, and then clean the grouting area 1 Adjacent all around put foam spacer strip 6 (material is polyurethane sponge, the single size that adopts is: wide 10cm, height 5cm, length 400cm), press channel steel bar 5 on foam spacer strip 6 again (single size is: Width 12cm, height 5cm, length 400cm), at last the gap between the road surface and the foam isolation strip 6 is filled up with leak-stopping agent 4 (water-based silica gel).

Embodiment 2

[0023] The average flatness of the adjacent asphalt pavement before construction of the poured composite pavement is 6.3 mm, which is poor, and the rest are the same as in Example 1.

Abstract

The invention relates to an edge sealing method for grouting construction of a grouting-type composite pavement. The method includes steps of: during a cooling step after a large-pore asphalt mixtureis paved and before the grouting construction, cleaning the pavements neighboring the grouting zone and placing foam separation strips on the peripherys neighboring the grouting zone; pressing the foam separation strips with channel steel strips, and filling the seam between the pavement and the foam separation strips with a plugging agent. Through the edge sealing method of combination of the foam separation strips, channel steel and plugging agent, due to certain solidness of the edge sealing material, during a starching step after the grouting construction of the grouting-type composite pavement, a hairbrush can push the material in parallel, so that a certain liquid level is formed to the slurry in the grouting zone. The pavement is grouted fully and is improved in appearance and construction quality. The method is suitable for an uneven pavement, has good slurry sealing effect, is simple in construction, has no pollution caused by the plugging agent after grouting, allows repeatedutilization of the separation strips, and reduces construction cost.

Description

technical field [0001] The invention relates to an edge sealing method for grouting construction of poured composite pavement, which belongs to the technical field of road construction. Background technique [0002] Pour-in composite pavement is a pavement that combines rigidity and flexibility by pouring cement-based grouting materials into the large-pore asphalt mixture matrix. It has the flexibility of asphalt pavement, good crack resistance, and no joints. And it has the characteristics of high rigidity, large bearing capacity and good anti-rutting performance of concrete pavement. At present, the poured pavement has been proved by engineering application practice, which is both rigid and soft, and has good anti-rutting performance. [0003] Cement-based grouting is a very important step in the construction of poured composite pavement, which directly affects the appearance and construction quality of the pavement. Most of the cement-based mortar used is black and gray...
