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.deDeformationGranular pavement layersHeavy Vehicle SimulatorS-N curvesConference PresentationWolff, H., Visser, A., & De Beer, M.
