        abstract = {Locally available soils are readily available and relatively cheap, but they are often problematic and do not satisfy the required geotechnical properties. These require locally available soils with good bearing capacity and strength properties. Volume change behaviour and low bearing capacity are major problems that pose by black cotton soil to the geotechnical engineer. To improve these properties the common method followed is stabilization. Soil stabilization using industrial waste materials has been widely recommended for developing countries for the construction of various elements of pavements. Rapid industrialization also causes production of huge amount of solid waste materials whose disposal creating lot of environmental problems. Calcium carbide residue (CCR) and Fly Ash (FA) are recognized as waste products from acetylene gas and power plant production respectively. However, the application of CCR to civil engineering work is very limited, especially for soil stabilization. 
In order to obtain the optimum content of CCR and CCR:FA blender Standard Proctor compaction, unconfined compression test (UCC) and California bearing ratio (CBR) tests are conducted. The UCC samples are tested under different curing periods (7, 14, 21 and 28 days) and CBR tests are carried out for a curing period of 3 days. 
From this study, it is revealed that for mixes of BC Soil + 6% CCR and BC Soil + 8% CCR + 10% FA are considered as optimum to improve the black cotton soil for pavement construction.},
