Among the geosynthetics, the two-way geogrid is a kind of reinforcement material, which is different from other materials due to its relatively high force and neatly distributed grid structure. Because the sand and soil on both sides of the grid can be directly contacted through the mesh, the interaction between the two-way geogrid and the soil is increased.
Biaxial Geogrid for highway is mainly reflected in two aspects: one is applied to the roadbed of general highways to enhance the stability and bearing capacity of the roadbed; the other is to be applied to the lower layer of asphalt highway pavement to prevent or delay reflection cracks on the road surface The emergence of or repair or refurbish the pavement. Biaxial Geogrid for highway can change and improve the role of sand and gravel in strengthening the roadbed. This is due to the high modulus performance of the warp-knitted two-way geogrid and the good occlusion of its grid with the sand and gravel layer, forming a high friction interface in the sand and gravel layer, which hinders the lateral direction of the sand and gravel layer. Move, and at the same time disperse the pressure better.
