1.It is capable of expansion and contraction,and it can be folded during transportation and stretched during construction,It constitutes a strong lateral restraint and stiffness structure by filling with materialsuch as sandstone or concrete.2.It is formed by light material with stable chemical properties which is resistant to abrasion,photooxidation,acid,and alkali,It is suitable for different soil and desert conditions.
3.It has a higher lateral limit,anti-skid,and anti-deformation,and can effectively enhance the bearing capacity of the roadbed and load distribution.
