摘要 本文研究了三种沥青抗剥落剂对克炼90号基质沥青老化前后性能的影响,结果表明三种沥青抗剥落剂提高了沥青的高温粘度;针入度和软化点分别发生了下降和上升;沥青延度在加入抗剥落剂之后没有发生显著变化;但耐热性和抗老化能力均发生了不同程度的提高,其中MAS的提升效果最佳。 The influence of three different asphalt anti-stripping agents on properties before and after aging of Kelian-90 base asphalt was researched. The result indicated that all the anti-stripping agents increased the high-temperature viscosity and softening point, and decreased the needle penetration, the ductility didn't dramatically change after adding anti-stripping agents, nevertheless, the heat resistance and ageing resistance enhanced for different level, and MAS had the best effect.
