     This paper presents an experimental study to reuse Olive Mill Wastewater (O.M.W) in civil engineering. Sewage of olive oil is rich in polyphenols and the treated one in a thermal way has been characterized and used in the stabilization of different types of soil. We started our work with the characterization and classification of different soils in different regions of Morocco, where the production of the O.M.W is abundant. In this study of consolidation, we measured the axial distortion of some samples in accordance with time in a constant load of each type of soil. To determine consolidation coefficients, we applied the Casagrande’s and Taylor’s methods. The experimental results show that the use of O.M.W in the consolidation of soils is an encouraging solution to build paths in rural areas.
