Geomembrane in the roadbed is not only strengthening the subgrade, but also plays a role in the anti-seepage and anticorrosion. The geomembrane has good heat resistance and cold resistance. good chemical stability, high rigidity and toughness, good mechanical strength, environmental stress cracking resistance and tearing strength. With density is rising, the mechanical properties and barrier properties will be a corresponding increase, heat resistant, and the tensile strength is higher; It can resisit the corrosion of acid, alkali and organic solvents and others.
