Abstract
Laboratory test programs on gravel are rare due to the maximum grain size of the material. In this paper an experimental
program with triaxial tests under cyclic loading and oedometric tests on highly compacted gravel specimens, representa-
tive for bridge backfills materials, is summarized. It is used to calibrate a hypoplastic constitutive model, which includes
an extension for intergranular strain to account for the cyclic loading behaviour. So far calibrated parameter sets of this
soil model are scarce in literature, especially for coarse grained materials. The calibrated parameter set can be used in
numerical studies, e. g. on the cyclic soil structure interaction of integral railway bridges
