This article studies the effect of stabilization through incorporation of cement and lime on the bearing capacity of soil from BUGANGA in the Democratic Republic of Congo, with the aim of using it in road construction. Physical, identification, compaction, and bearing tests were carried out in the laboratory on the natural soil as well as after stabilization. The results show that the soil is a fine, sandy clay with low plasticity consisting of 47.25% fines and has low bearing capacity. The addition of cement and lime increases the soil bearing capacity, with cement being more effective than lime. With 10% cement, the CBR rate increases from 5.37% to 46.32%, while with 10% lime, it increases from 5.37% to 28.916%. Soil stabilized with 10% cement or lime is suitable for use as a foundation layer for paved roads, while that stabilized with 5% cement or lime is suitable for platform layers for roads.
