Abstract: In developing countries like India the biggest handicap to provide a complete net -work of road system is the limited finances available to build road by the conventional methods. The construction cost can be considerably decreased by selecting local materials including local soils for the construction of the lower layers of the pavement especially the sub-grade. Civil Engineers are in search of new competitive materials, which can be suitable and effectively used to face many challenges that have cropped up with time in the world. In India 20% the land areas is clay soils and are expansive in nature. These lands are found to be expensive for construction as well as maintenance of roads. Rice husk ash (RHA) is a pozzolanic material that could be potentially used in soil stabilization, though it is moderately produced and readily available. Plastic bottles is considered as a waste material which cause environmental issue. This paper compares the strength of clayey soil reinforced with waste plastic bottles and RHA with 0%, 10%, 20% 30%, 40%, 50% by weight of soil. The results indicate that the proposed method is very effective to improve the engineering properties of the clayey soil in terms of index properties, bearing capacity, compressive, and shear strength, which further enhanced the stability.
