| 中文摘要: |
| 采用SBR/有机蒙脱土（OMMT）复合材料对沥青进行改性，研究改性沥青的常规性能、流变性能及高温贮存稳定性。结果表明，与基质沥青相比，SBR/OMMT复合材料改性沥青的针入度减小，软化点升高，低温性能明显改善，高温弹性和抗变形性能提高；随着复合材料中OMMT用量的增大，改性沥青的针入度减小，软化点升高，高温弹性和抗变形性能提高；改性沥青的高温贮存稳定性较好。 |
| 英文摘要: |
| The asphalt was modified by SBR/organic montmorillonite(OMMT) composite，and the conventional properties，rheological behavior and high-temperature storage stability of the modified asphalt were investigated.The results showed that the penetration of the modified asphalt decreased，the softening point increased，the low temperature performance improved significantly，the resilience and anti-deformation ability at high temperature increased when compared to those of the unmodified asphalt；the penetration of the modified asphalt decreased，the softening point increased，the resilience and anti-deformation ability at high temperature increased as the addition level of OMMT increased；the modified asphalt possessed better high-temperature storage stability. |
