MD is capable of building relationships between chemical structures of material and its macroscopic properties. This study first conducts a literature review of the various applications ofMDin asphaltmixture studies. A summary is made on the techniques and approaches adopted by researchers, and the main application areas of MD in asphalt mixture studies so far. Next, based on the basic concepts of MD, an analysis is performed to evaluate the strengths of the different techniques and approaches adopted, including the types of molecular models employed. Also evaluated are their relative abilities in explaining the behaviors of asphalt mixtures, such as mechanical properties, self-healing and rejuvenator diffusion behaviors, and the stability of asphalt-aggregate interfacial bonding under the influence of several factors. Based on the results of these evaluations, the limitations of MD applications in asphalt mixture studies would be identified. Finally, taking into consideration the strengths and limitations of MD, possible new techniques and potential new application areas are proposed and explained.enMolecular dynamicsAsphalt pavement mixturesMechanical propertiesDiffusion behaviorInterfacial behaviorConference-Full-textEngineering2021Road and Airfield Pavement Technologypp. 299-313Proceedings of 12th International Conference on Road and Airfield Pavement Technology, 2021longjiachu@chd.edu.cnhttps://doi.org/10.1007/978-3-030-87379-0_22
