The rockfill structures are widely constructed throughout the world and rockfills are largely used in these structures as main materials or filler materials. In the crust of earth dams, the rockfill materials role is to stabilize the body of the dam, however, the behavior of these materials in Particular their shear strength is not fully understood. In this study, different tests have been cond...
