Performance and Evaluation of Pavement Design with and without Using Geotextiles

Considerable increase in length of roads in India has increased the necessity of rapid, economic and sustainable construction methodologies. Thus at various construction stages of pavement the use of additives has gained significance over the period of time. Geotextile mainly has properties and functions such as providing reinforcement to soil mass, drainage, separation, stabilization of sub grade etc. Geotextiles are mainly available in woven and non woven types. In this project Woven Geotextile from local manufacturer was used. Geotextile was placed at various depths of samples during testing. Improvements in CBR values were recorded. Thus the pavement thickness using Geotextile at various depths was comparatively less than that of without using Geotextile. The results of CBR mould had been found to be much better when Geotextile had been placed in the middle of CBR mould than other depths.
