DSC modelling for Predicting Resilient Modulus of Crushed Rock Base as a Road Base Material for Western Australia Roads

In order to increase the applied efficiency of crushed rock base (CRB) in pavement structure design for Western Australia roads, the material modelling based on the experimental results was investigated, and the disturbed state concept (DSC) was used to predict the resilient modulus of CRB because o...

description In order to increase the applied efficiency of crushed rock base (CRB) in pavement structure design for Western Australia roads, the material modelling based on the experimental results was investigated, and the disturbed state concept (DSC) was used to predict the resilient modulus of CRB because of its simplicity and strong ability in capturing the elastic and inelastic responses of materials to loads. The actual deformation of DSC, at any loading state, was determined from its assumed relative intact (RI) state. The DSC equation of CRB was constructed by using a set of experimental results of resilient modulus tests, and an idealized material model, namely the linear elastic model, of relative intact (RI) part was considered. Analysis results reveal that the resilient modulus-applied stress relationships back-predicted by using the DSC modelling are consistent with the experimental results, so, the DSC equation is suited for predicting the resilient modulus of CRB specimen. However, the model and the equation coming from the test results are conducted in accordance with the Austroads standard, so further investigation and validation with respect to the field behaviours of pavement structure should be performed.
