摘　　要：本研究旨在探究聚苯乙烯、聚乙烯和聚丙烯对沥青高温性能的影响。通过实验评估了这三种聚合物改性剂对沥青的高温流变性能和抗老化性能的影响,并得出如下结论:聚乙烯表现出最佳的改性效果,能够在不同程度上提高沥青的高温流变性能和抗老化性能;同类型的聚合物在不同添加量下对沥青的改性效果也有所差异,随着聚合物添加量的增加,沥青的高温稳定性和抗老化性能逐渐增强。本研究结果对于高温地区聚合物改性沥青道路材料的设计与应用具有重要的参考价值。This study investigates the effects of polystyrene,polyethylene,and polypropylene on the high-temperature performance of asphalt.Experimental evaluations were conducted to assess the impact of these three polymer modifiers on the high-temperature rheological properties and aging resistance of asphalt.The following conclusions were drawn:Polyethylene exhibited the best modification effect,enhancing the high-temperature rheological properties and aging resistance of asphalt to varying degrees.Moreover,the modification effects of polymer modifiers of the same type varied with different additive amounts,with increasing amounts leading to improve high-temperature stability and aging resistance of asphalt.The findings of this study provide valuable insights for the design and application of polymermodified asphalt materials in high-temperature regions.
