摘　　要：利用马来酸酐(MAH)和引发剂过氧化二异丙苯(DCP)与基质沥青接枝反应制得改性沥青,研究了MAH用量、反应时间、温度、引发剂DCP用量对MAH转化率的影响,并用离析法与荧光显微镜研究了改性沥青与环氧树脂的相容性。结果表明:MAH添加量为沥青质量的4%,引发剂DCP用量为总单体量的0.5%,在120～140℃反应4～5h时可以获得较高的转化率,改性沥青与环氧树脂表现出良好的相容性。Modified asphalt was prepared with the reaction of maleic anhydride（MAH）、DCP and base asphalt.Products were characterized by fourier transform infrared spectroscopy.The effects of reaction time,temperature,initiator dosage on the conversion of MAH were studied.The compatibility of asphalt and epoxy resin was studied by segregation method and fluorescence microscopy.The results showed that： it can obtained a higher conversion rate with MAH 4% addition level quality of asphalt,the amount of initiator DCP at 0.5% of total monomers,the reaction temperature of 120-140℃ and the reaction time of 4-5h.It showed good compatibility of modified asphalt and epoxy resin.
