Embodiment 1
[0027] The average flatness of the adjacent asphalt pavement before construction of the semi-flexible pavement is 3.2mm, which is good. Before the grouting construction, use purge and drying equipment to clean the asphalt pavement and curbstones adjacent to the grouting area of the pavement; use double-sided adhesive with a width of 20cm to stick the asphalt pavement and curbstones adjacent to the grouting area, Gently tear off the double-sided adhesive release paper after pressing the double-sided adhesive tape; press and paste polyethylene foam cotton foam strips in the middle of the double-sided adhesive tape. The width of a single foam strip is 5cm, the height is 10cm, and the length is 5m. When in use, they are tightly spliced along the length direction section by section; then cover the foam strip with a polyvinyl chloride film with a thickness of 0.1mm and a width of 50cm, and press and bond both sides of the film to the double-sided adhesive tape at the bottom.
Embodiment 2
[0029] The average flatness of the adjacent asphalt pavement before construction of the semi-flexible pavement is 6.5 mm, which is poor. Before the grouting construction, use purge and drying equipment to clean the asphalt pavement and curbstones adjacent to the grouting area of the pavement; use double-sided adhesive with a width of 5cm to stick the asphalt pavement and curbstones adjacent to the grouting area, After pressing the double-sided adhesive tape, gently tear off the double-sided adhesive release paper; press and paste polyethylene foam cotton foam strips in the middle of the double-sided adhesive tape. The width of a single foam strip is 2cm, the height is 3cm, and the length is 0.5 m, tightly spliced along the length direction section by section during use; then cover the foam strip with a polyvinyl chloride film with a thickness of 0.01mm and a width of 10cm, and press and bond both sides of the film to the double-sided adhesive at the bottom .
Embodiment 3
[0031] The average flatness of the adjacent asphalt pavement before the construction of the semi-flexible pavement is 1.9mm, and the pavement has good flatness. Before the grouting construction, manually clean the adjacent asphalt pavement and curbstones around the grouting area of the pavement; use double-sided adhesive with a width of 50cm to stick the adjacent asphalt pavement and curbstones around the grouting area, and press the double-sided Gently tear off the double-sided adhesive release paper after the surface glue; press and stick polyurethane foam strips in the middle of the double-sided adhesive tape. The width of a single foam strip is 30cm, the height is 30cm, and the length is 2m. When using it, it is along the length direction The sections are tightly spliced; then cover the foam strip with a polyethylene film with a thickness of 0.2mm and a width of 150cm, and press and bond both sides of the film to the double-sided adhesive tape at the bottom.
