The effect of long-term aging on the rheology of warm mix asphalt binders

► The paper proposes a novel methodology for developing master curves for asphalt binders. ► It does not propagate the bias in the shift factor equation to the sigmoidal master curve. ► The proposed model predicts G* as a function of loading time, temperature and aging conditions. ► The Rediset WMA binder has the lowest stiffness, followed by the Evotherm, Cecabase and Sasobit.
