properties of the gravel fill, such as nonlinear shear modulus, are required in seismic analyses to evaluate the response to dynamic loading. From a series of Resonant Column and Torsional Shear (RCTS) tests on two types of crushed gravel fill, normalized shear modulus reduction curves were obtained as a function of cyclic shear strain. These curves are presented and compared to empirical
