Abstract

The soil bed should bear all the stresses transmitted by the structure. If the soil is weak and has not enough stability to resist heavy loading, the soil should be reinforced and stabilized. As the quality of the soil is increased, the ability of the soil to distribute the load over a greater area is generally increased. Stabilization using natural fibre is a cost effective and eco-friendly approach to improve properties of soil. The use of natural fibre is an initiative to maintain balance in nature. This study reveals around the reinforcement of soil by coir fibre, jute fibre, sisal fibre stabilization. The comparison between engineering properties before and after stabilization is made. The study is carried out to evaluate effects of fibre on engineering properties of a soil by carrying out unconfined compression test, permeability test, compaction test, consolidation test on soil sample. In laboratory testing of liquid limit, specific gravity along with grain size distribution is carried out for the classification ofsoil. The fibre is added by 0.25%, 0.5%, 0.75% and 1%. The experimental result with and without fibre reinforcement is compared to find optimum quantity of fibre reinforcement required to stabilize a weak soil along with the inference about effect on bearing capacity and shear strength.
