A brief review of the theory of material behavour is given as background to a discussion on the behaviour of granular materials as determined, from accurate measurments of elastic and plastic strains under fullscale Heavy Vehicle Simulator (HVS) testing. Analysis of these measurements indicated that granular materials behave elasto-plastically. Once the behavioural model of granular materials was determined, this model together with elastic and plastics deformation data collected from HVS testing on a number of sites throughout South Africa were used to develop a design model for granular pavement layers. The principle of S-N curves was used in the development of the design model.
