  ABSTRACT: Expansive soils in Sudan pose significant challenges to infrastructure due to volumetric changes with moisture fluctuations. This study investigates the effect of adding quick lime (4%, 6%, and 8%) on stabilizing expansive soil from Shambat, Khartoum State. Laboratory tests showed that the addition of lime led to a substantial reduction in the plasticity index, from 35.97% to 14.63%, and a remarkable increase in the California Bearing Ratio (CBR) value, from 1.7% to 50.7%. This indicates significantly enhanced soil strength. These results suggest that adding lime at 6% - 8% is effective in improving the soil's engineering properties, offering a sustainable and cost-effective solution for stabilizing expansive soil in Sudan.
