Geogrid Stitched  With Nonwoven Geotextile is manufactured from a polyester or fiberglass yarns knitted with non woven geotextile, bi-oriented grid,  without coating.

According EN 1 5381 –Geotextiles and geotextile related products R + STR + B.

R=reinforcement = reinforce the bituminous layer, stopping and controlling the cracking process.

STR= stress relief = function provided by a bitumen-saturated paving fabric (non-woven or purpose built composite) which, when is properly installed between a road surface and a new asphalt overlay  allows for slight differential movements two layers and thus provides stress relief, which delays or arrests crack propagation in the asphalt overlay.

B= interlayer barrier = function provided by paving fabrics,which act in conjunction with a bitumen layer as a barrier to the ingress of water and thus prevent or delay the deterioration of the pavement.

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.
