Fibre reinforced soils are gaining applications in civil engineering constructions due to improved engineering benefits of increased friction, permeability and shear strength. Particularly stabilization of granular materials with randomly distributed fibres has received much attention due to ease in mixing and placement. Though many studies are reported on improved angle of shearing resistance of fibre reinforced soils, studies on compressibility of synthetic fibre reinforced soils are limited. Hence, the present study is carried out to evaluate the compressibility of polypropylene fibre reinforced fine sand for fibres of 6mm and 12mm length in proportions of 0.5, 1.0 and 1.5% by weight. The compression indices of the fibre reinforced soils are determined from consolidation tests performed in oedometer. The study revealed that 12mm fibre reinforced sand has lesser compressibility over 6mm fibre reinforced sand at a given fibre content and the compressibility of sand stabilized with fibre of content of 1.5% (by weight) has resulted in compressibility less than that of low compressible clays.
