In this study, a well-known dynamic modulus prediction method, the Al-khateeb model, is evaluated to see how it performs to estimate dynamic modulus of asphalt mixtures designed and made based on Western Australian asphalt specifications and materials. The parameters needed for this model are obtained through laboratory tests on binder and mixture properties. Also, the actual dynamic modulus of asphalt samples is obtained through testing the samples which are made with the same mixtures and tested in Asphalt Mixture Performance Tester (AMPT) machine in a series of different loading frequencies and temperatures. Later the results of the model are compared with the actual results. The results showed that even though this model is very common in literature, it does not perform satisfactorily for mixtures in this study. Therefore, some modifications were made on the model to improve its accuracy.
