CZM analysis of secondary debondings induced by wedge splitting testing of multi-layer specimens

Abstract : In previous research efforts to study interfaces between asphalt pavement layers, the wedge splitting test is used in order to characterize the fracture bond of interfaces between layers of pavement materials that are mainly made of bituminous concrete, the main structural component of pavements of these structures. Due to the large size of the specimens extracted from in-situ test-track sections, secondary layers exist in those specimens. These secondary bituminous concrete layers debond during some tests, perturbing the results. Finite element modelling of the Wedge splitting tests is conducted using the Cast3M and ABAQUS finite elements systems, with a cohesive zone fracture models for the interface. This research demonstrates that consideration of mode-II fracture response (in-plane shear) within the secondary layer interfaces can better explain the behavior observed in experiments.
