In the seismic zones, the post earthquake static stability of embankment dams, has great importance for the geotechnical engineers. During a seismic event, the compacted embankment material is expected to experience little, if any, strength and stiffness reduction during and shortly after the design earthquake. A series of undrained post cyclic triaxial compression tests after cyclic loading were performed on a medium plasticity sand/clay mixtures. Testing was performed on isotropically and anisotropically consolidated specimens to investigate the effectiveness of aggregate fraction on the mechanical behavior of the mixtures. In addition, monotonic triaxial compression tests were also performed on the same sand/clay mixtures with the same initial condition. The results point out different peculiarities which can be of interest in assessing the mechanical behavior of the mixtures under post seismic shaking. The results show that effect of cyclic loading on post cyclic pore water pressure build-up is significant when pore water pressure build-up is considerably lower than the associated value in monotonic loading. The effect of aggregate content on post cyclic pore water pressure build-up is miner. However, when the aggregate content increases the shear strength increases.
