What are the types of geotextiles used in railway subgrade
Railway is more demanding than the highway, the railway subgrade is to bear and pass the orbital gravity and the dynamic structure of the train structure, is the basis of the track is to ensure that the train running an important building, the roadbed is a rock and soil structure, in a variety of topography, Geological and climatic conditions, such as floods, debris flow, earthquakes and so on. Therefore, geotextile in which the main play of his reinforcement and isolation, reinforcing the main material to enhance the shear and tensile deformation of the ability to prevent reflection of cracks in the road; isolation is the separation of different materials to maintain their own performance. As the geotextile itself is not waterproof, in the old road renovation over the asphalt mixture will form impermeable complex, in addition to preventing cracks and a certain degree of water defense, the railway subgrade is usually used in the two cloth a film complex Published, so with 600 grams of filament geomembrane more
400 g filament geotextile, 150 / 0.3 / 150 filament geomembrane
400 g filament geotextile, 150 / 0.3 / 150 filament geomembrane
300g, 400g range, I am specializing in the production of geotextile geomembrane and other materials, wish smooth
