Inordertoevaluatetheinfluenceofairvoidsonthemoisturedamageofhighvis-co elastic asphalt mixtures， 4 kinds of high viscoelastic asphalt mixtures had been designed.The Wheel Tracking Test and the Immersion Wheel Tracking Test have been conducted，dynamic stability and rut depth have been measured to investigate the influence of air voids contents on moisture stability.Results show that the air voids affects the moisture damage of high viscoelastic asphalt mixtures significantly.There is a suitable range of air voids with each gradation of high viscoelastic asphalt mixture respectively enabling to bring a good moisture damage resistance.
