摘要: 考察了S B R( 丁苯橡胶) 对C 9石油树脂改性沥青软化点、 针入度以及延度的影响, 并对S B R - C 9石油树
脂改性沥青机理进行了探讨。结果表明, S B R能有效改善 C 9石油树脂改性沥青的软化点, 当S B R的质量分数为
4 . 0%时, 改性沥青的性能符合《 公路改性沥青路面施工技术规范》 Ⅱ - C( J T J 0 3 6 - 9 8) 的要求。同时, 通过四组分( 饱和
分、 芳香分、 胶质和沥青质) 分析可知, C 9石油树脂可增加改性沥青体系芳香分的质量分数, 促进S B R在C 9石油树脂
改性沥青中的溶胀和吸附作用。由扫描电镜实验结果可知, 当S B R质量分数为5. 0%时, S B R与C 9石油树脂改性沥
青的相容性、 稳定性较好, 而且形成的银纹较多, S B R、 C 9石油树脂和沥青三者形成了稳定的高分子网状结构。

Abstract:

he effects of styrene butadiene rubber (SBR) on softening point, penetration and ductility of C9 petroleum resin modified asphalt were studied. The mechanism for SBR- C9 petroleum resin-modified asphalt was also discussed. The results show that SBR can effectively improve the softening point of C9 petroleum resin-modified asphalt. When introducing 4.0% mass fraction of SBR, the performance of modified asphalt could meet the required standard of JTJ036-98. The four components (saturation, aromatic, resin and asphaltene) analytical results indicate that the aromatics content of the modified asphalt system can be increased after adding C9 petroleum, thus the swelling and adsorption of SBR in the C9 petroleum resin modified asphalt can be promoted. Electron microscopy result demonstrates that, when the SBR content is 5.0%, the C9 petroleum resin modified asphalt shows good compatibility, stability, and numerous crazes. A three pitch stable polymer network structure might be formed for the SBR, C9 petroleum resin, and asphalt system.
