A Laboratory Investigation and Evaluation of Polypropylene Fibers for Stabilising Weak Pavement Subgrade

Among various methods of soil stabilization, one is to reinforce the soil with fibres. Soil here is reinforced with polypropylene fibre of length 24mm with varying percentage by mass of soil as 0.25%, 0.5% 0.75% 1.0% 1.25% and 1.50%. The soil was tested and basic properties were identified. Unconfined compression tests have been carried out to draw inferences about the effect of polypropylene fibres on strength of soil. This study also finds out the optimum dosage of polypropylene fibre by analyzing the results and obtaining the best values possible
