The damage healing performance of asphalt mixture was evaluated by combining macro and micro methods. Based on the semicircular bending tensile test, the effects of aging degree, damage degree, healing time and healing temperature on the damage healing performance of asphalt mixture were studied by digital speckle correlation method(DSCM).The results show that the macro and micro indexes change with similar characteristics. With the deepening of aging degree, the damage healing performance of styrene butadiene styrene(SBS) modified asphalt mixture gradually deteriorates, and the change of the damage healing performance of base asphalt mixture is not obvious. The healing rate of asphalt mixture after thermal aging is close to that of asphalt mixture after ultraviolet combined aging. With the deepening of the damage degree, the damage healing performance of base asphalt mixture and SBS modified asphalt mixture is significantly reduced. The damage healing performance of base asphalt mixture is better than that of SBS modified asphalt mixture, and the damage healing performance of SBS modified asphalt mixture is more significantly affected by the damage degree. The higher the healing temperature and the longer the healing time, the better the damage healing performance of asphalt mixtures.
