| 摘 要： | 利用苯乙烯-丁二烯-苯乙烯三嵌段共聚物（SBS）与蒙脱土（MMT）及其共混物分别对沥青进行了直接复合改性和共混物复合改性，测试了改性剂用量不同的SBS改性沥青、MMT改性沥青以及SBS与MMT质量比（m（SBS）／m（MMT））不同的共混物复合改性沥青的物理机械性能，同时还对不同m（SBS）／m（MMT）的SBS／MMT共混物复合改性沥青及SBS／MMT直接复合改性沥青的高温储存稳定性和相形态作了测试分析。结果表明，SBS／MMT共混物复合改性沥青的常规性能整体最优。 |

| Abstract: | The asphalts were modified with admixing simple SBS, MMT directly and blending SBS/ MMT complex. The physical mechanical properties of SBS and MMT individually modified asphalts, which the quantity of modifiers were different, or asphalt binders modified with SBS/MMT complex at different quantity ratio of m （SBS） /m （MMT） were determined. Meanwhile, high temperature storage stability and morphology of asphalt binders modified with SBS/MMT complex additives at different quantity ratio of m （SBS） /m （MMT） and admixed individually with SBS, MMT were tested and analysed. The results showed that asphalt binders modified with SBS/MMT complex additives have the best performances among them. |
