railway construction geotextile Introduction:
Geotextiles are often used for separation and stabilization in the construction of roads. The woven geotextile’s separation action prevents the mixing of dissimilar soils allowing each soil layer in the road structure to function as intended. The high tensile strength and low elongation properties of woven geotextiles impart stability into the road section reducing rutting and extending roadway life.
railway construction geotextile Feature:
- It is produced by spinning, needle punching process with super-strength polyester chip, so that the total carrying capacity is further raised.
- It can keep primary characteristic for more long time, not liable to deform and break down.
- It shows great characteristics at cid and alkali resistance, insect resistance and anti-mycotic.
- Good water permeability.
- Withstand High temperature and freezing, and is able to adapt to the different outer environment.
- Light in weight, and can be packed as buyer require. So it is convenient to transport , storage and construct.
