Description
Polyester geogrid Composite with Nonwoven geotextile is Polyester Geogrid Stitched With Nonwoven Geotextile Coated By Bitumen is an Asphalt Reinforcement Composite that High density Polyester geogrid with light weight Pet Spunbond Nonwoven Fabric . It's an Asphalt Reinforcement Polyester Composites,they are stitched together and coated by bitumen to strengthen the bond with the asphalt layers . The asphalt layer to increase the tensile strength to prevent road surface crack caused by foundation crack reflection. The chemistry stability is good, the hot-stability is good, anti-weary dehiscence, anti-low temperature shrinkage crack, postponement reduction reflection crack.

Production Line
Application
1. It reinforce old asphalt concrete road surface and asphalt layer, and prevents damage ;
2. It is used for rebuilding cement concrete road surface into composite road surface and restraining reflection caused by block contraction .
3. It is used in road expansion and improvment project and crack caused by old and new combination position and uneven sedimentation ;
4. It is used in soft soil base reinforcement treatment , is favorable for soft soil water separation and concretion,restrains sedimentation effectivly,distributes stress uniformly and improve overall strength of road base;
5. It is used for preventing contraction crack caused by new road semi-rigid base layer,and reinforces and prevents road surface crack caused by foundation crack reflection.
