Abstract: Soil is the basic foundation for any civil engineering structures and is one of nature’s most abundant construction materials for base. The most important part of a road pavement is subgrade soil and its strength. It is required to bear the loads without failure. If strength of soil is poor, then stabilization is normally needed. Subgrade is sometimes stabilized or replaced with stronger soil material so as to improve the strength. Numerous methods are available in the literature for soil stabilization but sometimes, some of the methods like chemical stabilization, lime stabilization, cement stabilization, fly ash stabilization adversely affect the chemical composition of the soil. In this study bitumen emulsion, cement and lime were mixed with dredged soil to investigate the relative strength of gravel soil in terms of Unconfined Compression Test (UCC), Bearing Capacity and California Bearing Ratio (CBR). The effect of bitumen emulsion, Cement and Lime on the geotechnical characteristics of cement and lime mixtures was investigated by conducting various tests like CBR and UCC. A little cement added to provide better soil strength. It is observed that excellent soil strength results by using cationic bitumen emulsion (CMS) with little quantity of cement used as filler. The appropriate mixing conditions for gravelly soil with CMS Bitumen emulsion have been first attempted. This is followed by deciding four particular material conditions to show the variation in dry density and CBR value to achieve the best possible strength properties of gravel soil. However, in this study, without additives soil was tested to find the Optimum Moisture Content (OMC), CBR value, Plasticity Index and Unconfined Compression Strength.
