  4. Abstract:
  5. Master curves of asphalt binders and mixtures have been traditionally used to evaluate their rheological behavior in the linear viscoelastic range. Different analytical models are available to describe the master curves of bituminous binders and mixtures. No models are currently considered universal for all modeling purposes. In this research, the general structure and capabilities of some of the most commonly used analytical models were investigated. Then, based on the patterns of phase angle master curves of ten neat and modified asphalt binders, four groups of master curve shapes were defined. The goodness of fit of the models for the different groups of master curves was used to develop a guide for selecting the most promising master curve model for a particular binder
