摘　　要：基质沥青中加入阻燃剂后会提高沥青的阻燃性能,同时也会影响沥青的路用性能,针对AC-16密级配混合料以及三种阻燃剂对沥青的阻燃性能及混合料路用性能的影响进行试验研究,提出隧道用阻燃沥青的设计过程中必须综合考虑阻燃性能和路用性能进行选择,对于隧道路面阻燃沥青的选用具有一定的参考价值。Flame retardants added into asphalt can improve the fire-retardant properties, and affect the asphalt pavement performance at the same time. AC-16 dense-graded aggregate and three flame retardant are conducted test research about their influence towards fire retardant property and mixture performances, presenting that it is necessary to consider flame retardant property and road performance. It can provide reference for selecting retardant asphalt in tunnel pavement.
