Abstract

SBS modified hard asphalt was prepared by de-oiled asphalt and radial SBS at 170 by high speed mixer. The samples were evaluated by conventional properties and fluorescence microscopy. Conventional properties showed that SBS drastically improve the high temperature stability and low temperature crack resistance of hard asphalt. Stabilizer improve the high temperature storage stability of asphalt obviously. Fluorescence microscopy showed that mean particle size of SBS in asphalt phase become larger as the increase of penetration, which indicate disperse of polymer in asphalt become difficult for harder asphalt. As a result, the macroscopic properties of modified asphalt were related to microstructure. In order to achieve desired macroscopic properties, SBS should be dispersed in asphalt uniformly and continuously.
