Study on the Influence of Blending State of Aged and Virgin Asphalt on the Tensile Behavior of Asphalt–Aggregate Interface
Publication: International Conference on Road and Airfield Pavement Technology 2023
ABSTRACT
The mechanical behavior and interface failure morphology of asphalt and aggregate in reclaimed asphalt mixture are related to the blending state of aged and virgin asphalt. In this study, the pull-out tests of asphalt–aggregates interface under different blending state of aged and virgin asphalt were carried out, the tensile failure morphology were analyzed. Results indicated that with the increase of blending time and temperature, the tensile force increased to an extent and then remained unchanged. In the short blending time and low temperature, there were uneven weak interlayer regenerated in the interface, and was more likely to failure. The correlation between the blending state and the tensile force and failure morphology was analyzed. The research results are helpful to reveal the internal relationship between the blending state of aged and virgin asphalt and the road performance of the mixture.
