Review on application and functions of Geosynthetics in development of Roadway

Abstract

“Geosynthetic is defined as a planar product manufactured from a polymeric material that's used with soil, rock, or other geotechnical-related material as an integral part of an engineering project, structure, or system”.  Geosynthetics are successfully want to fulfil variety of functions that contribute significantly to the great performance of roadways. They include the functions of separation, filtration, reinforcement, stiffening, drainage, barrier, and protection. One or more of those multiple functions are utilized in a minimum of six important roadway applications. The applications include the migration of reflective cracking in asphalt overlays, separation, stabilization of road bases, stabilization of road soft subgrades, and lateral drainage. This paper reviews study of varies road engineering methods using technical textiles like geo textiles in rural areas, the kinds, basic characteristics, function and properties of Geo-synthetics Consequently. The review states whether and under what conditions geosynthetics (geogrids and geotextiles) increase the structural capacity of pavements and under what conditions geosynthetics increase the service lifetime of pavements and various cost-effective advantages of geosynthetic use.
