摘要：In this article, heavy fraction (>350 degrees C) of tire pyrolysis oil was used to modify road bitumen. Experiments were carried out to investigate the effect of the modification conditions, such as blending temperature, shear rate, blending time, and admixing amount of heavy fraction on the properties of modified asphalt. The results revealed that the heavy fraction could be used as the modifier for road bitumen, and the proper modification conditions were the temperature range of 140-160 degrees C for 10 min, shear rate of 2,000 rpm and the proportion of heavy fraction 1 wt%, and that the modified asphalt showed excellent ductility before and after the aging test.
