Composite clay is a mixture of clay, as the main body and aggregates, which are floating within the clayey matrix. Undrained behavior of composite clays in its natural or compacted state e.g., core material of embankment dams has a great importance for the geotechnical engineers. An extensive test program was conducted on kaolin-gravel mixtures to investigate the effects of aggregate on the cyclic deformational properties, including shear modulus and damping ratio. Test results reveal that shear modulus for various mixtures, depends on aggregate content, shear strain amplitude, number of loading cycles and initial confining stress. Meanwhile damping ratio mainly depends on aggregate content and shear strain amplitude and is less affected by the number of loading cycles
