  ABSTRACT: The soils in the Diamniadio urban hub are expansive and have low bearing capacity. Construction in this area often requires the removal of native soils over certain depths, generating significant volumes of marl excavated materials that clutter construction sites. Due to their poor geotechnical properties, the reuse of these excavated materials in construction poses major challenges to engineers. This study investigates the effects of lithostabilization on the physical and mechanical properties of marl excavated from the Diamniadio urban hub to enable its valorization in road subgrade applications. Sand additions of 15%, 25%, 35%, and 45% were tested, using both dune sand (DS) and beach sand (BS). Results show that adding sand increases the bearing capacity of the marl, reduces its water sensitivity, and makes it suitable for construction use. It was observed that the granulometry of the added sand has a positive effect on lithostabilization outcomes.
