Usage of woven geo-textiles in the construction of subgrade in flexible pavements

Abstract

Objective: In this research work, emphasis was made on examining the quality of geotextiles in the road construction in flexible pavements and replacement as a binder. Methods: This paper examines about the usage of woven geotextiles in flexible pavements. The locally available soil is used for the tests. Different test are performed for soil along with geo-textile. In CBR test geo-textile is installed at different depths in soil such as 3, 6 & 9 centimeters in the mould. Findings: From this study, layer of woven geo-textile introduced at the center shows the better performance than those of other layers at different depths. Application/Improvement: The use Geo-textiles in the flexible pavement can rise the service life of the pavement than the previous pavements. Geo-textiles of both natural and synthetic are helpful in improving the geo-technical properties of soil.
