Abstract: “Clayey and high plasticity fine grained soils usually create too much problems for earth fill works. In general, if the geotechnical properties of the existing soil are inappropriate, it is either replaced with a suitable fill material or improved on-site via various methods. This study investigated the use of lime to stabilize high-water-content high-plasticity clay for use in fill layers of an industrial region roads. Usually, drying of high-water-content clays is almost impossible at construction sites. At the beginning, MH high plasticity silt type of soil was dried first and then stabilized with hydrated lime and hydraulic lime at optimum water content and results of both lime are compared. The hydraulic lime was chosen for the real application and then, the research investigates the possibility of stabilizing high-water-content claywith a special lime called hydraulic quicklime without drying the soil. High plasticity soil was obtained from the Hadımköy district of Istanbul city”
