摘　　要：以废轮胎粉提取的芳烃油为降黏调和剂,与成品SBS改性沥青共混得到降黏型沥青胶结料,将此种胶结料应用于G111国道通辽段2019年度的大中修工程中,取得了较好的施工效果,为内蒙古东北部地区缓解因施工期短、大中修工程量大给国道大中修工程带来的困难提供了良好的经验,同时,也为继续优化SMC常温拌和剂配方提供了工程经验支撑。The aromatic oil extracted from the waste tire powder is used as the viscosity-reducing blending agent,and blended with the finished product of SBS modified asphalt to obtain the viscosity-reducing asphalt cement.This kind of cement is applied to the large and medium maintenance project of Tongliao section of G111 national highway in 2019,with good construction results.It can provide good experience for the difficulties brought by the large and medium maintenance project of the national highway in the northeast of Inner Mongolia due to the short construction period and large quantities of large and medium maintenance project.At the same time,it can also provide the engineering experience support for the continuous optimization of the formula of SMC normal temperature mixing agent.
