Asphalt-Aggregate Interface Failure Mechanism and Its Characterization Methods
Asphalt mixture is a multi-phase complex composite of coarse aggregate, asphalt binder, air voids, and asphalt-aggregate interface. Failures often start from interface, which is often considered as the weakest link in asphalt mixture with respect to its formation, strength, and durability. This article introduces the current research on asphalt-aggregate interface failures mechanism and its effect factors, focus on experiments and constitutive models related to interface bond strength and stress analysis, and interface mechanical behavior under different loading modes was also discussed. Diseases related to interface degradation, such as fatigue failure, moisture damage, as well as interface imperfect bonding were summarized. The researches show that current interface models ignore some special loading and extreme adverse conditions, which make asphalt-aggregate interface mechanical properties difficult to be perceived. Therefore, models account for complex variable conditions, viscoelastic behaviors, mixed-mode damage, and dynamic loading would be an urgent task in the industry, which will provide a theoretical and scientific support for the optimization of asphalt mixture design.
