| 摘 要： | 通过对基质沥青、SBS及PPA 3个因素的沥青流变性能的研究表明：SBS改性沥青的动态剪切流变性能与基质沥青的动态剪切流变性能呈相似的变化规律;且同一基质沥青进行改性时,SBS与PPA掺量越高DSR值越大,当SBS加入量为4.0％～5.2％、PPA为0.0％～0.8％时,SBS,PPA掺量与车辙因子呈现较好的相关性.

| Abstract: | This research studies the influence of base asphalt.SBS and PPA on rheological properties of SBS modified asphalt. The results indicate that the rheological properties of SBS modified asphalt and base asphalt show similar change regularity; for the same base asphalt, the value of DSR of SBS modi- fied asphalt increased with the increase of SBS and PPA. When the SBS content is 4.0~ 5.2% and PPA content is 0.0~0.8%, the content of SBS and PPA are well related with G＊/sinδ. |
