Feasibility of Geo-textile in Transportation Engineering- An Overview
Keywords:Geo-textile, separator, drainage, filtration, reinforcement
Nowadays various geo-synthetic materials like geo-grids, geo-textile, geocomposites, geo-nets, geomembranes, geo-synthetic clay liners, geo-foam, and geo-cells are extensively used in various civil engineering applications and projects because of their useful characteristics. Various critical situations arise due to increasing traffic day by day. Due to high traffic volume, the roads are damaging before its life. The black cotton soil posses high swelling property. Due to heavy rains, compression and contraction takes place in the form of undulations. To overcome such a problem we can use geo-textile materials. Geo-textile is one of the first textile products in human history. Geo-textile increases the bearing capacity of soil and the improvement of soil strata beneath the highway
pavement so that undulations can be avoided and the life span of road increases. Geo-textile has been used very successfully in transportation engineering for over 30 years. Geotextiles are better materials for infrastructural works such as roads, , and many others. Geo-textiles play an important role in modern pavement design and maintenance applications. Worldwide its usage is high in general & transportation engineering in particular. In this review, paper geo-textiles have been discussed in length with regard to its basic characteristics, function, and applications like reinforcement to improve the performance of road, in-pavement drainage system, in road construction, maintenance and erosion control, in separation and sub-grade stabilization and in support systems. The focus of this paper is on a better understanding of this relatively new tool available to the transportation engineers.
