Abstract Granulated polymer anti-rutting additive PLAST.S could improve performances of asphalt and asphalt mixtures. In order to analyze the modification mechanism, main technical indexes of different PLAST.S modified base asphalts were firstly stu-died compared with corresponding base asphalt processed by the same technology. Then road performances of PLAST.S modified asphalt mixtures by dry process and wet process were analyzed. At last, combined with the physical form of PLAST.S both in asphalt and asphalt mixture, also with the improving effect of PLAST.S on asphalt and asphalt mixture, modification mechanism of PLAST.S was analyzed. The research results show that penetration and ductility of PLAST.S modified asphalt decrease, whereas softening point of PLAST.S modified asphalt increases, and this variation trend becomes more evident with heating and mixing time increasing. Adding PLAST.S into asphalt mixture can improve high temperature performance and water stability while it has little effect on crack resistance at low temperature. PLAST.S mainly plays the role of physical modification for asphalt and asphalt mixtures. The physical form of PLAST.S is changed at high temperature, and performances of asphalt mixture are improved by reinforcement, void-filling, constraint effect and so forth after cooling. Properties of asphalt are improved by thickening effect.
