橡胶沥青具有高粘度的特点，而温拌剂改善了沥青混合料的施工和易性，实则是降低了沥青混合料的同温度粘度。关于温拌剂的加入是否会对橡胶沥青的老化性能产生影响，目前研究较少。通过室内短期老化模拟、长期老化模拟以及老化性能评价，分析Evotherm温拌剂的掺加及其剂量对橡胶沥青老化后的高温粘度、车辙因子（G*/sinδ）及蠕变劲度S等性能指标的影响，结果表明：Evotherm温拌剂没有改善橡胶沥青在拌合和施工阶段的抗老化性能的能力；老化指数（AIPAV，AIRTFO）随Evotherm温拌剂剂量的增加而减少；老化使得添加温拌剂的橡胶沥青的低温抗裂性能有一定程度的提高；综合考虑施工高温下的老化和使用过程中的长期老化，建议选择12%Evotherm的剂量。

Rubber modified asphalt has a high viscosity,and with warm asphalt additives the rubber asphalt mix-ture viscosity can be reduced at the same temperature,which is of great help for improving the workability of as-phalt mixtures. There are limited studies on the influence of warm asphalt additives on the aging properties of the rubber modified asphalt. In this study,rubber modified asphalt samples containing different contents of Evo-therm are aged through short-term aging,long-term aging simulation in the lab. And the high temperature vis-cosity,G*/sinδand creep stiffness S of these specimens are tested after aging simulation. The results show:Evo-therm can not improve rubber modified asphalt’s anti-aging properties in the mixing and construction phases;aging index(AIPAV,AIRTFO)decreases with increasing Evotherm content;the rubber modified asphalt’s low tem-perature crack resistance improve when mixed with Evotherm after aging;considering the high temperature con-struction aging and long-term aging of pavement operation,a mixing content of 12%Evotherm is recommend-ed.
