This paper evaluates whether the temperature reduction production during Warm-Mix Asphalt (WMA) leads to a beneficial effect on short- and long-term aging properties of asphalt binder. For this purpose, two 70/100 penetration grade virgin asphalt binders were used. First, the material was short term aged at three different temperature, 123 °C, 143 °C, and 163 °C, and then, long term aged. Shear complex modulus was then measured with the Dynamic Shear Rheometer and the data used to generate master curves and fit the 2 Spring 2 Parabolic 1 Dashpot model. Glover–Rowe parameter and crossover-temperature were next determined to further investigate the effect of aging temperature on the properties of the material. Significant differences were observed between 163 and 123 °C for both short- and long-term aging conditions. However, a remarkable difference between 143 and 123 °C could be detected only for the short-term aged binder. Finally, the statistical analysis confirmed the experimentally observed trend. Based on the results and analysis presented in this paper, it can be hypothesized that a reduction in the temperature of short-term aging, which is commonly experienced during WMA production, may result in an overall substantially milder aging.
