Abstract:

The dynamic water scouring effect caused by the vehicle load was investigated with a self-designed apparatus in this paper. The void ratio, water absorption and split tensile strength of asphalt mixture of AC-13 were monitored during the freeze-thaw cycle test by two different immersion modes (static immersion mode and dynamic scouring immersion mode). The microstructure changes were also tested with the aid of X-ray computed tomography (CT) to explore the mechanism of water damage of asphalt mixture both from the macroscopic and mesoscopic points of view. The experimental results show that with the increase of freezing-thawing cycles, the void rate under dynamic scouring mode and static immersion mode increases by 47.62% and 22.5%, respectively, and the water absorption rate increases by 263.2% and 86.4%, respectively. The freeze-thaw splitting tensile strength ratio (TSR) declines by 34% and 24.9%, respectively. The CT images analysis reveals that new frost-heave voids are produced in the inner part of mixtures, and some of the aggregates are also spalled at the outer edge. Dynamic water scouring will accelerate the shedding of fine aggregates and expand the volume of voids correspondingly. The deterioration of the anti-water property of the mixture under dynamic water scouring was more obvious.
