There is Black cotton soil in most parts of central and western parts of India and covering approximately 20% of the total area of India and it has been a challenge to highway engineers since this soil is highly susceptible to moisture changes. Soil stabilization is a technique to improve the engineering characteristics of the soil. Certain soils possess undesired properties making their use in the constructions very difficult. These include high permeability, high compressibility, and reduced shear strength. Modification of soil by chemical admixtures is a common stabilization method for such soils. The main objectives of the proposed project is to determine the index and engineering properties of Black cotton soil, determination of engineering properties of fish net fibre modified soil, reducing swelling tendency of moist compacted Black cotton soils, to check the efficacy of fish net fiber (Grid type) reinforced soil as a fill material through laboratory model studies. Soil stabilization using fishing net can help to enhance soil strength, stabilize near-surface soil layers and mitigate the risk of soil liquefaction. For roads with heavy traffic and locations of extreme climatic conditions, soil stabilization is generally recommended and the method can be adopted after a proper study. This investigation aims at checking the feasibility of using waste fishing net fibers and improving the strength and compaction characteristics of the soil. Waste fishing net fibers are added in a layer-wise and an optimum configuration has arrived.
