Abstract: One of the most problematic soils which lay several challenges to civil engineers is expansive soil. Swelling, shrinking and strength instability is the salient problems of this soil, which necessitates the treatment. In this study, different percentage of lime (2,4,6,8,10%) and GGBS (5,10,15,20,25%) are used to stabilize the clayey soil. A set of experimental tests (Atterberg limits, Standard Proctor compaction, Unconfined compressive strength (UCS), and durability) is carried out for investigating the effects of binders on the strength and durability of the clayey soil. The outcomes of this experimental study showed that optimum moisture content (OMC) increases while maximum dry density (MDD) decreases by the addition of lime and vice versa case of GGBS. Furthermore, the combination of lime and GGBS significantly enhanced the strength characteristics and durability of the clayey soil.Strength properties of all soil specimens increased by the extension of curing time (7,14 and 28 days). Atterberg limits of the treated soil declined by raising the percentage of GGBS.
