Soil stabilization is a critical technique in civil engineering to improve the engineering properties of soil, makingitsuitable for construction purposes. This abstract presents a novel approach to soil stabilization using waste lime andurea, aimingto enhance soil strength and reduce environmental impact. Waste lime, a byproduct of various industrial processes, andurea,acommon agricultural fertilizer, are both readily available and cost-effective materials. When applied to soil, waste limeandureareact chemically to form stable compounds, reducing soil plasticity and increasing its load-bearing capacity. The Present Studyinvestigates the effectiveness of stabilizer i.e. calcium carbonate precipitation (waste lime) and urea to increase the strengthofsoilsubgrade. This study addresses the contemporary need for sustainable and eco-friendly soil improvement techniquesincivilengineering projects. Waste lime and urea, recognized for their cost-effectiveness and minimal environmental impact, areemployed as stabilizing agents to enhance soil properties. Laboratory experiments involve varying concentrations of limeandureato analyse their impact on the soil's mechanical and chemical characteristics. The aim of the study is to improve soil cohesion,strength, and overall stability. For this, different tests were performed in the lab which is pH, compaction, liquid limit, plasticlimit,Specific gravity, compaction tests, and Unconfined compression Test (UCS).
