| 摘 要： | 研究了稳定剂(W)对SBS改性沥青显微结构、性能的影响。结果表明:稳定剂改变了改性沥青的微观结构,改性剂粒子由互不相连的球形分布或“互穿网络”结构变为分散、均匀分布甚至成为和沥青之间没有明显相界面的均相结构,改善了改性剂和沥青之间的相容性,提高了SBS改性沥青的软化点,提高了SBS改性沥青的热储存性能。 |

| Abstract: | The nature of SBS modified asphalt was investigated when the stabilizer W was added. The results show that the asphalt microstructure was changed for the stabilizer put in. The structure of modified particle was discontinuous distribution or interpenetrating polymer networks (IPN) structure when the stabilizer was not added. They were evenly distributed even there were no sharp pulse interface between asphalt and modified particle after the stabilizer was added. The bitumen compatibility and softening point of SBS modified asphalt was improved, so was the storage stability. |
