Abstract: With the increased global demand for energy and increasing local demand for aggregates, it has become expensive to remove inferior soils and replace them with strong materials. One way to overcome this problem is to improve the existing soil enough to provide strength and conform to engineering standards. Two soil samples, Black cotton soil and Sandy soil were stabilized using a natural fibre Coir and a synthetic fibre Nylon. Former is a problematic soil because of its expansive nature. Although the second sample is not problematic in nature, it is used in this study to compare the influence of stabilization for different soil types. In order to stabilize the soil, both stabilization and reinforcement techniques are adopted. The soil samples were treated with cement and then fibres were added randomly at 0.5, 1 and 1.5% by weight of soil sample taken for different aspect ratios of 50 and 100. A series of California Bearing Ratio Tests and Unconfined Compressive Strength Tests were conducted and the best optimum proportions of fibres were determined.
