Experimental Investigation of Use of Geosynthetic in Road Pavements

Abstract

The increase in urbanization led to the scarcity of the land for road construction, due to which land with high water content and low bearing capacity had to be used. In the past history many different methods have been proposed so as to improve the unfavourable conditions prevailing in various locations such as the locations with low bearing capacity soil, water logging conditions, land movements, etc. The application of geosynthetics has proved to be the most promising solution of all the alternatives. Various types of geosynthetics have been used to fulfil various functions such as filtration, separation, drainage, reinforcement, mitigation of reflective cracks, by the use of a single or combination of two or more geosynthetics. This use of geosynthetics has also contributed towards the goal of being one of the most economical and practically applicable alternatives. This paper also studies the characteristics and the basic information of geosynthetics commonly in case of pavement such as geotextile, geogrid, geonets, geomembrane, GCL and geo- composite having an unequivocal function. It includes the comparison of the pavement constructed with the help of geosynthetics and the conventional pavements against various parameters such as bearing capacity, moisture content, economy, maintenance required and the life period of the pavement. The use of geosynthetics is increasing at a very rapid rate and is being accepted worldwide and hence  there rises the necessity for detailed study.
