Improving the swelling and shrinkage properties of problematic soils in various parts of the world is an important research topic in engineering applications. In recent years, industrial side products have been frequently used to improve the engineering properties of problematic clay soils and both environmental and economic benefits have been obtained. In this study, the effect of different additives on the Atterberg limits of high plasticity clay soil was investigated. Different ratios of lime (L), fly ash (FA) and silica fume (SF) were added to the clay soil. Liquid limit and plastic limit tests were carried out according to ASTM D4318 standard on the samples prepared with and without additives. As a result, it was determined that while the liquid limit value of clay soil decreased with the addition of lime, fly ash and silica fume, the plastic limit value increased. Among the additives used, it was determined that the most effective additive material on the Atterberg limits was lime.
