Pavement Anti‑crack Geotextile
Core Functions
1. Prevent Reflection Cracks
It absorbs stress and blocks cracks from the old base spreading upward to the new asphalt surface, effectively reducing pavement cracking caused by temperature changes and foundation settlement.
2. Reinforce & Stabilize Pavement Structure
It disperses vehicle load evenly, improves the tensile performance of asphalt pavement, and enhances overall structural stability.
3. Isolate & Waterproof
It isolates the upper and lower structural layers, prevents water infiltration into the subgrade, avoids water damage such as road boiling and loosening.
Introduction of Pavement Anti‑crack Geotextile
Pavement anti‑crack geotextile is a high‑performance geosynthetic material specially used for road and highway engineering, mainly needle‑punched polypropylene filament or staple fiber geotextile. It is laid between the old pavement base and new asphalt layer to prevent reflection cracks and improve road service life.

3. Isolate & Waterproof
It isolates the upper and lower structural layers, prevents water infiltration into the subgrade, avoids water damage such as road boiling and loosening.
4. Improve Construction Quality & Extend Service Life
It reduces road maintenance frequency, lowers long‑term maintenance costs, and prolongs pavement service life by 3–5 years.
Ⅱ. Application Scenarios
·Highway reconstruction and widening projects
