Characterization of asphalt concrete by multi-stage true triaxial testing

, 2005
The feasibility of an existing servo-controlled true triaxial (cubical) apparatus for evaluating the mechanical response of nominal 4-in. cubical specimens of asphalt concrete (AC) under multi-axial stress states has been investigated.

Generalized Matsuoka–Nakai criterion considering hydrostatic pressure dependence in the brittle–ductile region

Deep Underground Science and Engineering, EarlyView.
Three sets of strength data were selected, including hydrostatic pressure independent within the brittle region (HPI‐B), hydrostatic pressure dependent within the brittle region (HPD‐B), and hydrostatic pressure dependent within the brittle–ductile region (HPD‐BD). For HPI type, the failure envelope within the deviatoric plane remains constant.
