1 Geotextile helps to enhance the soil mass' tensile strength and
non-deformability and structural stability so as to improve soil
2. It can effectively make the concentrated stress diffuse,
transfer or decompound, and prevent the soil mass against the
destruction of outside force.
3. Its mesh is hard to jam by virtue of the compliancy and motility
of the reticulation formed by indefinite form
4. High water permeability-it can keep good water permeability even
in the pressure of soil and water.
5. Corrosion resistant-it is made from polypropylene fiber or
terylene or other chemical fiber, featuring resistance to acid and
and oxidation, non-corroding, no worm-eaten.
6. Easy construction-low weight, easy operation, simple
1). Reinforcement: Used in the constructions of highway, railway,
airport, dam, prevent slope dike, retaining wall, etc. to improve
2). Protection: To prevent the bank from eroding by wind, wave
,tidal and rain. Used for the projects such as revetment, slope
protection and bottom protection, anti-soil erosion,etc.
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 .
