Abstract
Basing on an experimental detailed study, this paper presents the storage time effect on the mechanical behaviour of the western northern Nancy area (France) a silty soil. This study has as objective at explaining and quantifying the effect of ageing time due to the storage of samples after compaction on the shear strength. That's why, a significant number of undrained unconsolidated triaxial shear tests was carried out on altered samples. These latter were stored safe from the air and the moisture during various periods after being compacted. The results show an important increase in both the undrained shear strength and the deformation modulus by silt rigidification during the ageing time at constant volume and in undrained conditions.
