Abstract

Soil stabilization is one of the most popular techniques used for improvement of poor subgrade soils like black cotton soil and silty soil. Black cotton soil has high shrinkage and swelling behaviour with variation in moisture content, due to which failure of pavement occur. In silty soil slaking and dispersion occurs leading to formation of voids as proper bonding between individual particles are lacking. To overcome these problems it is necessary to improve the properties of soil by reinforcement or by replacing the soil itself. Replacing the existing soil might not be an economically viable option. The reinforcement materials used are in the form of fibers which are randomly oriented or in the form of sheets which are placed in layers in soil. Geosynthetics are man-made materials formed from synthetic fibers like polypropylene, polyethylene, polyester or natural fibers like coir, jute and ramie. More recently the use of geosynthetics in particular geotextile made of synthetic fiber in machine direction and natural fiber in cross machine direction (hybrid) are coming up. This paper describes the available knowledge on the use of geosynthetics in soil reinforcement applications particularly in the field of soil subgrade stabilization. The different categories of geosynthetics and their functions were also discussed.
