Abstract
A new advanced triaxial testing machine, named University of Illinois FastCell (UI-FC), was used for determining in the laboratory stress path loading effects on resilient properties of a crushed aggregate. A series of constant stress path compression and extension tests performed using the UI-FC indicated significant differences in aggregate resilient properties computed under both assumptions of isotropy and cross-anisotropy. The resilient responses were properly characterized using a nonlinear stress dependent model for the three-dimensional stress states.
