Introduction:
Plastic woven film yarn geotextile is a kind of geotextile made by extruding, cuting film,stretching to film yarn (monofilament, split-film yarn) ,weaving.
Applications:
Used in the areas of highway, railway, dyke, water project construction, tunnel for its reinforcement, filtration, isolation and drainage.
The main reason of above disease is as follows:
1. expand with heat and contract with cold because the temperature
2. ageing of bitumen and elasticity decline of surfacing
3. substrate has crack and horizontal fall head
4. material which used and construction method ,etc
According to the cracking of bitumen concrete road ,when we add the surface on the before road or semi-rigid surface , we can use the high performance polyester spunbond between new surfacing and old surfacing , then we can prevent above disease .
