THE DEVELOPMENT OF A PERMANENT DEFORMATION DESIGN MODEL FOR UNBOUND GRANULAR MATERIALS WITH THE SHAKEDOWN CONCEPT

The paper describes the results of several repeated load triaxial tests performed on a crushed rock aggregate at different stress levels. The development of the resulting permanent deformation which accumulates with the repeated loading is described and compared with the types of responses usually described by the shakedown approach. It will be shown that the existing shakedown approach can describe some, but not all, of the observed responses. Thus a modified set of possible responses will be defined in shakedown terms and some explanations of the differences from the conventional approach are given. An empirical permanent deformation design model is formulated. For the covering abstract see ITRD E118503.
