Abstract
The degradation of the bituminous pavement structures is due to the several external loads (climatic conditions and traffic) and the weak bond between layers. Thus, it is important to take into account the interface behavior in the pavement computational design which is never considered actually. In order to provide reliability and efficiency of the design methods, the interface characterization study is required. In this study, a monotonic tensile test was performed for better understanding of the global and local structure behavior by using the Digital Images Correlation (DIC) analysis. The obtained results allow us to characterize the constitutive law of interface and mechanical parameters such as: stiffness, damage evolution, and release rate energy.
