Woven geotextile is a permeable geosynthetic material made from synthetic fibers through industrial weaving processes. Its core feature is the interweaving of two sets of parallel yarns, warp (longitudinal) and weft (transverse), to form a regular mesh structure. It has high tensile strength, good permeability, and strong stability, and is mainly used in geotechnical engineering, water conservancy engineering, transportation engineering, and other fields. It undertakes core functions such as separation, reinforcement, protection, and filtration, and is an indispensable environmentally friendly engineering material in modern infrastructure construction. Its quality standards strictly follow industry specifications such as ASTM D 4439 and AASHTO M 288.
