摘要 阐述了沥青的老化机理,采用红外光谱法研究了有机蒙脱土对沥青抗紫外老化性能的影响,结果表明,SBS改性沥青、有机蒙脱土改性沥青和有机蒙脱土SBS改性沥青经紫外老化后都会发生老化反应,但有机蒙脱土SBS改性沥青的抗紫外老化能力明显高于前两者。 This article describes aging mechanism of asphalt and studies influences of organic montmorillonite on anti- ultraviolet aging property of asphalt by IR spectrum. The results show that aging reaction of SBS modified asphalt, organic montmorillonite modified asphalt and organic montmorillonite-SBS modified asphalt will occur after ultraviolet aging, but organic montmorillonite-SBS modified asphalt has higher UV resistance than the former two.
