The material of biaxial tension plastic geogrid is similar with the material of unidirectional tension plastic geogrid. Its chemical property isn’t active too. It is extruded by macromolecule polymers, and formed by longitudinal and horizontal tensions. This kind of material has high tension strength in both longitudinal and horizontal directions. This kind of structure provides a interlock system for the soil and is suitable for the improvement of roadbed with large area permanent load, such as treatment of soft soil foundation and reinforced earth structures.
