Wetting and Drying Compacted Soil-Lime Mixtures

Abstract

Soil treatment technique with lime is widely applied in the world in the field of earthworks. It allows reuse of materials useless for implementation embankments. But the lack of knowledge of behavior of cycles, drying/wetting in terms of volume and water change, the mechanical performance of the treated soils, the optimal lime dosage are the origin of the limited application of this technique to embankment and the no mentioned in the GTS (technical Guide soil treatment with lime and/or hydraulic binders) of this technique. The soil studied is A-4. Lime dosages are chosen based on two objectives: the amelioration and stabilization to cycles drying/wetting of soil.
