Analysis of the Influence of Polymeric Fabric Waste on Soil Subgrade

This study focuses on the productive utilization of discarded and used polymeric fabric bags in the construction of rural roads. The paper describes the analysis of soil–plastic fiber waste composite. The materials used are locally available silty sand from NIT Jamshedpur campus and waste discarded cement bags. Experimental tests have been conducted to determine engineering properties of soil as envisaged by Indian standard codes. Apart from this, a series of California bearing ratio tests have been done on reinforced soil and un-reinforced soil under soaked and unsoaked conditions. Reinforcement of soil has been done in two different ways: small pieces mixed with soil sample and inserting layers of fabric in the specimen. Comparative study has been done to determine the optimum value of CBR for ascertaining the most effective soil–fiber mix. To evaluate the behavior of un-reinforced and reinforced soil subgrade, PLAXIS-2D software is used.
