摘　　要：为提升SBS改性沥青温拌再生质量,通过制备再生剂、温拌剂,研究再生剂、温拌剂掺量对温拌再生SBS改性沥青的基本技术指标、旋转黏度和高温性能的影响。结果表明:环氧官能团的加入能够有效改善老化的SBS改性剂的相关性能,使老化的SBS改性剂得以再生,且环氧官能团的最佳掺量为8%;随着环氧官能团掺量的增加,SBS改性沥青旋转黏度均逐步增加,老化的SBS改性剂的黏性逐步恢复、流动性能提升;制备温拌剂B,使其掺量由0增至10%后,SBS改性沥青临界温度降低率达到7.6%,整体降幅较小。Through the preparation of regenerative agent,temperature,mixing agent,through different blending,measurement of the basic technical indexes,rotational viscosity and high temperature performance for this paper.The results show that:The addition of epoxy functional groups can effectively improve the related properties of aging SBS modifier.The aging SBS modifier can be regenerated,The best metering is 8%.With the increase of epoxy functional groups,the rotational viscosity gradually increased,the viscosity of aging SBS modifier was gradually restored,and the flow performance was improved.When the warm mix agent B increases from 0 to 10%,the critical temperature reduction rate reaches 7.6%.
