Product Description
Coated Polyester Geogrid With Nonwoven Geotextile Composite
Product Introduction
Coated Polyester Geogrid With Nonwoven Geotextile Composite is an asphalt reinforcement composite that High density Polyester geogrid with light weight PET Spunbond Nonwoven Fabric . 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.
Product Function
It can widely apply in the water conservation, the municipal administration, the building, the transportation, the subway, the tunnel, the environmental protection and so on.
