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.
