| Abstract: | To observe dispersed state of modifiers SBS and SBR in matrix asphalt with scanning electron microscope,simultaneously to contrast differential scanning calorimetry(DSC) of two kinds of modified asphalt.By contrast to microstructures of observed modified asphalt and to its thermal stability,the modified mechanisms of SBS and SBR towards the asphalt are thoroughly approached further. |
