The Treatment of soils using lime and cement is one of the appropriate techniques that provides solutions for poor geotechnical soils used in road construction, as subgrade layers. The present paper consists of a comparative study of bearing and sustainability of silty soils treated with lime and/or cement. The Tests carried out on samples of treated silty soil showed a great improvement in workability and bearing capacity compared to a natural one. It was also noticed that the soil that was treated with 5% of cement, and with 1% of lime and 4% of cement gives the highest values of CBR (Californian Bearing Ratio). However, the highest durability of the treated soil was obtained by mixed treatment (1% of lime and 4% of cement), which values the mixed treatment efficiency. It should also be noted that the proposed solution fits sustainable development well
