A four-point bending test for the bonding evaluation of composite pavement

The aim of this paper is to present a specific four-point bending test with a specific model to help investigate the crack initiation and propagation at the interface between layers of composite pavements. The influence of the geometry on the delamination phenomenon in specimens is analyzed. Considering the deflection behavior of specimens, both experimental and analytical results are compared. Two different types of interface (concrete / asphalt and asphalt / concrete) are tested in static conditions. Different failure mechanisms whose mainly delamination is observed. The crack mouth opening displacement is monitoring by means of linear variable differential transducer (LVDT). The strain energy release rate is provided and compared successfully to the literature.
