For the coal mine tunnel fire of asphalt pavement,this paper expounds the necessity of tunnel asphalt flame retardant,introduced the type of flame retardants and the study of road performance,analyzed the scheme of flame retardant mechanism and the flame retardant perform-ance testing methods of asphalt mixture. By a lot of tests and research,the result shows that the asphalt mixture could delay combustion and flame retardant.%针对煤矿巷道沥青路面火灾的危害，论述了巷道沥青阻燃的必要性，介绍了常见的阻燃剂类型和路用性能，分析了阻燃剂的阻燃机理和沥青混合料阻燃性能的测试方法，并结合大量试验和研究，指出阻燃剂的掺入可以达到推迟燃烧，阻止燃烧的目的。
