So why can geotextiles be used to prevent cracks in highway reconstruction?
1. What we need to know is that the cracks are caused by the tensile stress of cement and asphalt overlay when the temperature decreases, and the existence of geotextile can reduce the tensile stress under the asphalt surface.
2. Geotextile has good ductility, so its widening range can be increased. When shear occurs at the joint of highway, the existence of geotextile can alleviate it and play a transitional role.
3. Geotextile has a good anti-seepage effect, and geotextile has a good porosity. However, due to the adhesion of asphalt, it is expected to play the role of anti-seepage and water separation, so as to prevent the water of the pavement from penetrating into the subgrade, so as to protect the subgrade and prolong its service life.​

Fabric application field (1) It is used as reinforcement in the backfilling of retaining wall or for anchoring the panel of retaining wall Construction of wrapped retaining wall or abutment Application of Geotextile in construction (2) Reinforce the flexible pavement, repair the cracks on the road and prevent the pavement from reflecting cracks (3) Increase the stability of gravel slope and reinforced soil, and prevent water and soil loss and freezing damage of soil at low temperature (4) The isolation layer between ballast and subgrade, or between subgrade and soft foundation (5) Isolation layer between artificial fill, rockfill or material yard and foundation, and isolation between different frozen soil layers Inverted filtration and reinforcement.
