Use Of Jute Geo Textile For Strengthening Of Sub Grade Of Road Work

Abstract

Jute Geo - textiles have been successfully used for reinforcement of soil to improve bearing capacity. In this paper the jute Geo - textiles as a tensile materials have been used for reinforcement of different kind of soils. Laboratory California bearing ratio (CBR) tests were performed to investigate the load penetration behavior of different 3 kinds of soils ( B. C. Soil, Murum & both soil ) with different kind of jute Geo textiles ( Woven jute Geo – textiles thickly netting & with thinly netting ). Samples of soil tested for CBR without reinforcement & samples are also tested with jute Geo textiles. Laid at various distance from top (i.e 1/3, 2/3 & half distance) of compacted thickness of soil suitability for improvement of sub grade in all aspect is calculated. Result shows that soil sample of 50% B. C. soil & 50 % murum with thick jute Geo textiles laid at 1/3^rd distance from top are most economical & increases the CBR to considerable extent.
