Description
Fiberglass Geogrid Stitched With Geotextile is the composite of fiberglass geogrid combined with nonwoven fabric or geotextile. It installed between two asphalt layers, the main function is to reduce reflective and fatigue cracking, reduce rutting, extend pavement structural life.
Fiberglass geogrids: 25*25KN, 30*30KN, 40*40KN, 50*50KN, 60*60KN, 80*80KN, 100*100KN, 120*120KN
Nonwoven fabric: 20g/ 30g/ 50g/ 80g/ 100g
Or do customerised as per your requirements.

Application
1. Maintenance of old asphalt road reinforcement of asphalt pavement.
2. Converting old cement concrete road into composite road.
3. Restraining reflection cracking caused by block shrinkage.
4. Preventing and controlling the cracking caused by new and old combination and uneven settlement.
5. Road extension.
6. Reinforcement of soft soil foundation and overall strength of roadbed.
