Railway engineering geotextile testing
[ 2023-12-04 ]
Geotextile, also known as geotextile, is a permeable geosynthetic material made from synthetic fibers through needle punching or weaving. Geotextile is one of the new materials of geosynthetics, and the finished product is in the form of a cloth, with a width of 4-6 meters and a length of 50-100 meters. Geotextiles are pided into woven geotextiles and non-woven filament geotextiles p>
