Expansive soils, prone to significant volume changes with moisture fluctuations, pose a considerable challenge in construction and infrastructure projects due to their potential to cause structural damage. Traditional soil stabilization methods, such as the use of cement can be costly and environmentally detrimental. In this paper utilization of waste materials, including fly ash, and lime as a sustainable alternative material for controlling the swelling behaviour of expansive soils is presented. Through laboratory experiments and analysis, the effects of waste materials on soil properties were evaluated. The results demonstrated that incorporating waste materials can effectively reduce the swelling pressure, swell potential and compression index of expansive soils. Increased moisture content enhanced the engineering properties and provided an environmentally friendly solution for soil stabilization. This paper reveals the development of cost-effective and sustainable practices for improving the performance of expansive soils in construction
