Abstract: ABSTRACT This study is undertaken on a light grey (expansive) and a red clay soil samples taken from within Addis Ababa. The change in engineering properties of these soils treated with SA- 44/LS-40 chemical alone, lime alone and combinations of both at different application rates are investigated. The investigation of the modifications in engineering properties of the stabilized soils are made using laboratory tests that include soaked CBR and CBR swell tests, swelling pressure test, Atterberg limit tests, percent swell test and free swell tests. The modifications in engineering properties were evaluated after curing the treated sample for fourteen days. From the study, it is observed that the application of lime alone and SA-44/LS-40 chemical with lime shows improvements of varying degree on the engineering properties of both the light grey and the red clay soils. However, no specific mix ratio showed the maximum improvement in all the engineering properties of each soil. This suggests that before deciding for large-scale applications, the desired improvement level of the engineering properties of a particular soil should be specified first, and tests be conducted for different mix ratios to arrive at the optimum one.
