Crack‑resistant Geotextile
Main Functions
1. Resist Reflection Cracks
It absorbs and disperses stress from the base layer, blocking old cracks from extending upward to the new surface layer, effectively reducing temperature‑induced and settlement‑related pavement cracks.
2. Pavement Reinforcement
It improves the tensile and anti‑deformation capacity of asphalt pavement, evenly distributes vehicle loads, and stabilizes the overall road structure.
3. Waterproof and Isolation
It prevents rainwater from infiltrating into the subgrade, avoiding subgrade softening, loosening and water‑caused pavement damage.
Introduction of Crack‑resistant Geotextile
Crack‑resistant geotextile, also known as anti‑crack geotextile, is a needle‑punched polypropylene geosynthetic material widely used in road and pavement engineering. It is mainly applied between old pavement layers and new asphalt overlays to control pavement cracking and improve road durability.
Ⅰ. Main Functions
1. Resist Reflection Cracks
It absorbs and disperses stress from the base layer, blocking old cracks from extending upward to the new surface layer, effectively reducing temperature‑induced and settlement‑related pavement cracks.
2. Pavement Reinforcement
It improves the tensile and anti‑deformation capacity of asphalt pavement, evenly distributes vehicle loads, and stabilizes the overall road structure.
3. Waterproof and Isolation
It prevents rainwater from infiltrating into the subgrade, avoiding subgrade softening, loosening and water‑caused pavement damage.
4. Long‑term Road Protection
It extends pavement service life, reduces maintenance frequency and lowers long‑term engineering costs.
