The aim of the experimental study was to identify the local deformation properties in a clayey material which can be activated at the macroscopic ultimate state known by critical state. The approach consists of an extensive study, based on a Scanning Electron Microscope (SEM) picture analysis, of the orientation of the clay particles characterized in the last stages of triaxial loading.
