Abstract

Modified mechanism of asphalt of PPA in conjunction with SBS is studied on from the microscopic view by experiments. These experiments include four constituents fluorescence microscopy infrared spectroscopy and DSC. The results show that the proportion of asphaltene increase and the proportion of colloid decrease because of PPA adding. Its can promote the dissolve dissolution of SBS modifier in order to enhance the network structure of asphalt.PPA contributes to the colloidal structure of asphalt conversion from sol to sol-gel structure. That is helpful to improve high temperature performance; aging-resisting performance and storage performance of SBS modified asphalt.
