| 摘 要： | 改性剂与沥青的相容性是决定改性效果和改性沥青制作工艺的关键因素，而聚合物改性沥青的相容性与基质沥青的组成、聚合物的剂量、聚合物成分结构以及贮存温度密切相关。利用热贮存稳定性试验系统研究了SBS与基质沥青的相容性。结果表明，线形SBS普遍比星型SBS具有较好的相容性，SBS含量小于3%时的改性沥青的稳定性也较好，沥青质含量适中、芳香分含量越小的基质沥青与SBS相容性也越好。

| Abstract: | The compatibility between SBS modifier and asphalt affects the modifier usage results and the asphalt blend technology, it is related with composition of base asphalt,content of polymer and blend tempature. The compatibility between SBS modifier and asphalt was studied with storage stability test. The results shows that liner SBS has super compatibility than radial SBS with asphalt, when content of SBS is less than 3%, SBS modified asphalt has very good compatibility, and asphaltenes content is proper, aromatics is larger, compatibility of SBS modified asphalt is also good. |
