[0002] Geogrid is a main geosynthetic material. Compared with other geosynthetics, it has unique properties and functions. It is often used as reinforcement material for reinforced soil structures or reinforcement material for composite materials. Geogrids are divided into four categories: plastic geogrids, steel-plastic geogrids, glass fiber geogrids and polyester warp-knitted polyester geogrids. The grid is a two-dimensional grid or a three-dimensional grid screen with a certain height made of high molecular polymers such as polypropylene and polyvinyl chloride through thermoplasticization or molding. When used in civil engineering, it is called geogrid. It can be well anti-corrosive and ensure strength by adopting composite structure manufacturing. Geogrids are buried in the road matrix to play the role of reinforcement.
