Mechanical analysis of a mixed mode debonding test for “composite” pavements
Abstract In order to investigate interlayer debonding near skrinkage cracks or joints of “composite” pavements, a four-point bending test on bi-layer structures is performed. Before mixed mode failure, the quasi-analytical calculations obtained by a specific elastic model match experimental results under static and controlled displacement conditions. Both the interface normal and shear stress intensities determined at the specimen edge lie within the range of values found in the literature for cement concrete overlays on a bituminous material type of interface. The strain energy release rate is calculated. Results are discussed relative to both data provided in the literature and testing campaigns.
