Abstract:
This paper deals with the testing and assessment of the bond behavior and the crack resistance of asphalt-concrete interfaces tested at different temperatures, which are necessary for the rehabilitation of rutted asphalt pavements with the so-called whitetopping technology. Different pretreatments of the interface were performed: without any treatment, using cement grout, using a combination of cement grout and synthetic dispersion, or using only synthetic dispersion. The mechanical and fracture mechanical properties were determined by means of the pullout test and a wedge splitting test. The tests were performed at temperatures of –10, 0, 10, and 22 °C (14, 32, 50, and 71.6 °F).
