Abstract: The oxidation of vacuum residue of Russian fuel oil M100 was studied with self-made device for 10 h under the oxidation temperatures 225 and 250 ℃ with the ventilation capacity of 0.2 m3/(h•kg). The results show that three asphalt of oxidized samples can meet well with technical requirements of road asphalt (JTG F40-2004) for 130#C, the standard grade of asphalt and bitumen and 110#C grade standards. A modifier SBS was added with the weight ratio of 1% to 5%, and the MAW-1-type stabilizer was also added with the mass ratio of stabilizers to SBS 1∶(10~15). Two polymer modified bitumen were in line with the standard of the SBS class I-A in the technical requirements (JTG F40-2004).

摘要： 对俄罗斯燃料油M100的减压渣油进行研究,利用自制的氧化装置, 控制氧化温度分别为225和250 ℃，通风量为0.2 m3/(h•kg)，氧化时间为 10 h。实验结果表明：氧化后样品的沥青3个主要性质数值符合道路沥青技术要求(JTG F40-2004)中130#C等级沥青的标准和110#C等级沥青的标准。添加改性剂SBS质量分数为1%~5%，并加入MAW-1型稳定剂，w(稳定剂)∶w(SBS)为1∶（10~15）。改性后的两种沥青均符合聚合物改性沥青的技术要求（JTG F40-2004）中SBS类I-A的标准。
