Improvement of Load Carrying Capacity of Soil using Jute-Geotextile

Abstract

A comprehensive study is performed on soil and jute-geotextile to improve the load carrying capacity of subgrade soil. An extensive laboratory experiments are carried out to verify the improvement of load carrying capacity for clay soil. Permeability test, unconfined compressive strength (UCS) test and triaxial test are carried out to verify the behaviour of soil considering geotextile material. The sample behaviour is checked for six cases (Case 1: without considering geotextile material in the soil sample, Case 2: h/2 depth, Case 3: h/3 depth each, Case 4: h/4 depth each, Case 5: h/5 depth each and, Case 6: h/6 depth each, where, h is the height of the soil sample). The result shows that the load carrying capacity increases when the geotextile is taken into account as compared to soil without geotextile. It is to be noted that the load carrying capacity increases for case 2 to case 4 considering jute-geotextile in the soil sample. However, the load carrying capacity decreases for case 5 and case 6, though, more layers of jute-geotextile is considered in the soil sample. Finally, an optimum method is proposed to develop maximum load carrying capacity of soil incorporating jute-geotextile.
