摘　　要：为生产高软化点改质沥青,通过提高反应釜温度,提高闪蒸罐真空度以及对原有改质沥青装置工艺流程优化调整,生产出软化点在118~130℃,结焦值大于60%的改质沥青。By increasing the temperature of the reactor,raising the vacuum level of the flash tank,and optimizing the process flow of the original modified asphalt plant,modified pitch with a high softening point of 118~130℃and a coking value greater than 60%was produced.

关 键 词：改质沥青 软化点 结焦值 真空度
