influence of jute fibre on cbr value of expansive soil

construction of structures on expansive soil is highly risky due to its susceptible behavior towards differential settlements. different soil stabilization techniques including soil reinforcement have been adopted to improve the properties of the unsuitable soils. in this present study, randomly distributed jute fibres have been used to improve geotechnical properties of expansive soil collected from south delhi (india).

california bearing ratio (cbr) tests were carried out on the expansive soil blended with jute fibres. jute fibres of length 10 mm and 30 mm were included in different percentages viz. 0.25, 0.50, 0.75, 1.00, 1.25 and 1.50 by the dry weight of the soil. the test results indicate that the inclusion of randomly distributed jute fibres significantly improves the cbr value of the soil. the optimum value of fibre content is found to be 1.25%. an improvement of 226.92% in cbr value of the reinforced soil as compared to unreinforced soil has been observed at the optimum jute fibre content. since jute is agricultural waste, the present study provides a cost-effective solution to problematic clayey soils.
