AbstractDecomposed granite soils, formed by weathering of the parent rock, exist widely in many areas of the world. The mechanical properties of this type of geomaterial, compared to clay and sand, are less extensively studied. In this study the small-strain shear modulus (G0) of a decomposed granite soil in Hong Kong was measured for a variety of packing densities and confining pressures, using the resonant column (RC) and bender element (BE) techniques, and the values of G0 obtained by the RC and BE tests were compared to study the effect of test method. It is found that the small-strain shear modulus of the decomposed granite soil is considerably lower than that of a benchmark quartz sand. Furthermore, the G0 values of the decomposed granite soil obtained by the bender element tests are significantly higher than those measured by the resonant column tests, whereas for quartz sand the two test methods are found to provide quite similar results.
