The key factor in construction sector is the soil investigation. To decide upon a stable construction, characteristics of soil are required to ascertain its feasibility. Properties of soils differ from area to area since they are of different classification/ types. Some soils i.e expansive soils are problematic soils due to their swelling and shrinkage nature. Many stabilization methods are in use in construction industry. Thus in this study, additives quarry dust and sodium chloride has been used to improve the compaction characteristics of the expansive soil. Using quarry dust as a additive is environment friendly where as sodium chloride involves less cost involvement. Quarry dust is used in percentages (10%, 15%, 20%) whereas sodium chloride is used in percentages (0.5%, 1%, 1.5%, 2%). Addition of these additives has significantly improved the compaction characteristics. Optimum combination of quarry dust and sodium chloride generated is in proportion 15% and 1% respectively.
