Abstract:
Fatigue cracking is one of the main distresses in asphalt pavement and its deterioration directly impacts the service and safety during the life cycle of road infrastructure. Recently, the fatigue characteristic of asphalt binder and its contribution to the anti-fatigue performance of asphalt pavement are gradually getting more attentions. Focusing and analyzing the fatigue and fracture characteristics of asphalt binder is of great significance for the national realization of long-life asphalt pavement in the future. In recent years, various laboratory testing methods and data modeling approaches have been developed for the binder fatigue and fracture performance evaluation, whereas the corresponding specification system has not been fully established. For the testing protocol, the accelerated fatigue procedures such as the linear amplitude sweep have been gradually implemented and verified with the time sweep fatigue test. Regarding to the data interpretation, the applications of the linear viscoelastic characteristics, dissipated energy, pseudo strain energy and fracture mechanics gradually drive the studies of binder fatigue and fracture from empiricism to accuracy. This paper systematically reviews the recent developments on binder fatigue and fracture testing protocols, damage characterizing approaches and fatigue life predictive models, followed by summarizing the existing problems and future prospects in this research area. This review would provide help and reference for the ongoing development of fatigue resistance design and long-life asphalt pavement technology. © 2024 Cailiao Daobaoshe/ Materials Review.
