A geosynthetic has been characterized by the American Society for Testing and Materials (ASTM) Committee D35 on Geosynthetics as "a planar item made from polymeric material utilized with soil, shake, earth, or other geotechnical engineering related material as a basic piece of a man-influenced venture, to structure, or framework." The geosynthetics that are routinely utilized as a part of the transportation business are geotextiles, geogrids, geomembranes, disintegration control covers and tangles, geosynthetic dirt liners, geocomposite seepage materials, and geonets. Those worried about the investigation, plan, establishment, also, execution of geosynthetics utilized in transportation offices center around particulars, outline philosophies, development methods, long haul execution, and financial aspects.

Geosynthetics have been and keep on being utilized as a part of all features of the transportation industry, including roadways, airplane terminals, railways, and conduits. The chief capacities performed by geosynthetics are filtration, waste, division, support, arrangement of a liquid obstruction, and natural protection.Generally, geosynthetic alludes to an item that is produced using polymeric material and is connected as a key segment in a structure or framework to accomplish engineering purposes. The prefix "geo" recommends whose application needs to do with soil, shake, as well as earth. There are some fundamental elements of geosynthetics to be specific detachment, support, filtration, waste, regulation, hindrance, surface disintegration control, and assurance; any geosynthetic item is relied upon to give at least one of the capacities. Utilizations of geosynthetics are generally found in common, transportation, geotechnical, ecological, hydrodynamics, marine, and private advancement engineering including streets, railways, dike, holding dividers, waterways, disintegration control, squander landfill, arrive recovery, sea walls, wharfs, crotches, revetments, aquaculture, farming, and mining. Notwithstanding, with the advancement of related items, the appropriate scope of geosynthetics can stretch out to regions other than the previously mentioned.
