dc.description.abstract

Hydrated Cement Treated Crush Rock Base (HCTCRB) is a unique road base material developed and commonly used for Western Australia roads. This paper presents the application of disturbed state concept (DSC) for the constitutive modelling of HCTCRB. DSC was adopted as the modelling approach because of its simplicity and yet is powerful in capturing the elastic and inelastic responses of materials to loading and unloading-reloading history. The DSC constitutive model depends on the main assumption that the actual material deformation, at any loading state, can be determined from its assumed relative intact (RI) state. DSC equations are derived based on an idealised material model of the RI state, namely linear elastic RI state. The use of the idealised linear elastic RI state leads to a unified stress-strain equation in terms of the stress and strain values at the maximum yielding and ultimate limit states. The DSC models are found to be in good correlation with the actual HCTCRB behaviour based on the test data. The proposed constitutive model is also suitable for predicting the resilient modulus of HCTCRB, which will be presented and verified.
