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.
Author Keywords: Cement, Lime, Soil, Stabilization, Bearing Capacity.

Abstract: (french)
Cet article étudie l’effet de la stabilisation par incorporation de ciment et de chaux sur la portance du sol de BUGANGA en RDC, en vue d’une utilisation dans la construction routière. Des essais physiques, d’identification, de compactage et de portance ont été réalisés au laboratoire sur le sol naturel et après stabilisation. Les résultats montrent que le sol est fin, argile sableuse peu plastique constitué de 47,25% de fines et a une faible portance. L’ajout de ciment et de chaux augmente la portance du sol, l’ajout de ciment étant plus efficace que celui de chaux. Avec 10% de ciment, le taux de CBR augmente de 5,37% à 46,32%, tandis qu’avec 10% de chaux, il augmente de 5,37% à 28,916%. Le sol stabilisé avec 10% de ciment ou de chaux est approprié pour être utilisé en couche de fondation pour les chaussées revêtues, tandis que celui stabilisé avec 5% de ciment ou de chaux est adapté pour les assises de plateforme pour les chaussées.
