| Abstract: |
| 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. |
