Product Description
Black Biaxial Plastic Geogrid Polypropylene For Road Construction
Product introduction
Bi-direction geogrid is nearly square .it used polypropylene and high density polyethylene as raw materials ,it is pressed into plate by melting extrusion, then punching ,heating and stretching
Product features
1,High tension resistance, high plane torsion resistance modulus, good creepresistance and stable chemical nature.
2,High machine damage resistance and durability and large friction factor with sandy stone
3,It can improve bearing force of foundation(normal improvement of above40%) and increase diffusion angle(average increase to 50 degrees from 38 degrees
4,Under the function of shaft times with same load, it can decrease 30%-40% of filling thickness for reaching same effect, when geotechnical grid reinforcement is used, road bed with same thickness can bear more 3-5 times
Product application
