摘　　要：针对隧道沥青路面火灾的危害,通过大量的试验和研究,明确了安全阻燃改性的技术途径,分析了方案的阻燃性能、阻燃机理及安全性,论证了该类安全环保型阻燃技术对于提高隧道沥青混凝土路面火灾安全的可行性。研究证实,该种阻燃方案可以实现沥青的阻燃、无毒、抑烟以及降低放热和发烟速率的作用,为火灾发生时的救援和逃生创造条件并争取时间,可极大改善和提高公路隧道的运行安全,降低火灾损失。By a lot of tests and research against the fire hazard of the tunnel asphalt pavement,the technological approach of modified safe flame retardant was determined.The scheme of flame retardant property,flame retardant mechanism and safety were analyzed.The feasibility of such kinds of safe and environmental protection flame retardant technology to improve the fire security of tunnel asphalt pavement was demonstrated.The research indicates that this flame retardant scheme can achieve the goal of flame retardant,nonpoisonous,reducing smoke,reducing heat release and the rate of smoke generating to create conditions and gain time for rescue and escape when fire occurs.Thus the operation security of highway tunnel can be improved and the fire damage can be reduced observably.
