Abstract

The invention relates to a preparation method of composite strengthening anti-cracking cloth. The composite strengthening anti-cracking cloth is compounded by knitting a geotextile and a glass-fiber geogrid, wherein the geotextile is glass-fiber polyester anti-cracking cloth with a gram weight of 120-160g / m<2> and a thickness of 0.66-1.08mm, and the adopted binding yarn has the linear density of 167-220dtex and warp or weft strength of 0.41-0.50N / tex in a knitting process. In the glass-fiber polyester anti-cracking cloth, the mass ratio of polyester fiber to glass fiber is 30:70-25:75. By improving the invention, the surface of the composite strengthening anti-cracking cloth is also provided with a dope layer. On the basis of the glass-fiber polyester anti-cracking cloth, the glass-fiber geogrid for a composite strengthening asphalt pavement is additionally arranged, and the composite strengthening anti-cracking cloth can not only prevent reflection cracks and water destroy, but also prevent and delay other cracks and increase the bearing capability of a road.

Description

technical field

[0001] The invention relates to a preparation method of a composite reinforced anti-crack cloth. Background technique

[0002] Glass fiber polyester anti-crack cloth is a non-woven fabric made of glass fiber mainly mixed with an appropriate amount of polyester fiber. It takes into account the strength of glass fiber and the flexibility of polyester fiber. It has good tensile and asphalt adsorption properties. It has good heat resistance and has high temperature stability when paving hot asphalt concrete. After rolling, the original glass fiber polyester anti-crack cloth makes the asphalt concrete and slurry seal tightly integrated into a whole through glass fiber polyester cloth At the same time, it plays a waterproof role, so that the water at the base will not penetrate through the cracks and the rain will not penetrate downwards. Its paving can also effectively improve the pressure concentration at the cracks, decompose the stress, increase the deformatio...
