摘　　要：为了探索常用的阻燃剂对温拌阻燃沥青混合料阻燃性能的影响,采用IFR、EG和Sb_(2)O_(3)三种不同阻燃剂制备了温拌阻燃改性沥青,开展了氧指数试验和直接燃烧试验后沥青质量损失率试验,并对直接燃烧后温拌阻燃沥青混合料的路用性能损失率进行测试。结果表明,IFR、EG和Sb_(2)O_(3)三种不同阻燃剂均能够发挥一定的阻燃作用;在掺量相同的前提下,EG阻燃剂的阻燃效果最佳,其次是IFR阻燃剂,最后是Sb_(2)O_(3)阻燃剂。In order to explore the effects of commonly used flame retardants on the flame retardant properties of the warm mixed flame retardant asphalt mixture,the modified asphalt was prepared with three different flame retardants of IFR,EG and Sb_(2)O_(3),and the asphalt mass loss rate after oxygen index test and direct combustion test were carried out,and the road performance loss rate of the warm mixed flame retardant asphalt mixture after direct combustion was tested.The results show that IFR,EG and Sb_(2)O_(3) three kinds of flame retardants can play a certain role in flame retardancy.Under the premise of the same dosage,the flame retardant effect of EG flame retardant is the best,followed by IFR flame retardant,and finally Sb_(2)O_(3) flame retardant.
