Review: Investigation and Evaluation of Polypropylene Fibers for Strengthening Weak Pavement Subgrade

Abstract

Among various methods of soil stabilization, one is to reinforce the soil with fibers. Soil here is reinforced with polypropylene fiber of varying percentage by mass of soil. The soil was tested and basic properties were identified. Unconfined compression tests have been carried out to draw inferences about the effect of polypropylene fibers on strength of soil. This study also finds out the optimum dosage of polypropylene fiber by analyzing the results and obtaining the best values possible.
