KEYNOTE PAPER: MECHANICAL PROPERTIES OF UNBOUND AGGREGATES. UNBOUND AGGREGATES IN ROADS. PROCEEDINGS OF THE 3RD INTERNATIONAL SYMPOSIUM, UNIVERSITY OF NOTTINGHAM, APRIL 11-13, 1989

This paper presents highlights of recent research efforts in the area of mechanical modeling of the resilient behavior of unbound aggregates in roads. Selected constitutive models are reviewed. These models address the factors which appear to be of most importance in describing the resilient behavior of these materials, such as nonlinear elasticity, total stress-strain relations, and incremental stress-strain relations. The application of nonlinear forms to granular materials is also discussed. This covers the proximity to failure, moisture condition, thermally induced stresses, dynamics, stress history dependency, residual stresses, and selected statistical analyses. A simple approach to conceptualization of the material and its behavior is proposed which is based on fundamental physical concepts. For the covering abstract of the conference see IRRD 827698.
