Abstract:
Due to its preparation and construction process being under relatively high temperature, traditional hot mix asphalt would result in not only a lot of energy consumption but also serious environmental pollution. Therefore, how to reduce the mixing temperature of asphalt mixture, as well as decrease environmental pollution and energy consumption, has become a common scientific issue and a technical hotspot for the researchers in road engineering area. The emergence of warm mix asphalt (WMA) has provided a novel and efficient solution for this technical problem. In the present work, the development history of WMA was introduced comprehensively. The warm mixing technologies existed worldwide and their technical mechanisms were summarized. The pavement performance of WMA was evaluated, and its novel preparation technologies and progress were described. It is in the hope that this paper could be helpful for the engineers to utilize the warm mixing technologies properly in designing asphalt mixtures and researchers to explore the new methods and directions of warm mixing technologies.
