摘　　要：近些年隧道建设与日俱增,隧道内环境特殊,路面易燃容易造成事故。研究开发了一种环保型阻燃橡胶沥青混合料,并与其他种类的混合料进行了不同性能的综合分析。环保型阻燃橡胶沥青混合料的基本性能与其他类型混合料不相上下,高、低温不易变形开裂,能够较好的抵抗水和荷载的作用;阻燃抑烟方面,环保型阻燃橡胶沥青混合料点燃时间长,质量损失小,烟气释放量少,阻燃效果较好,是一种性能优良的隧道用阻燃抑烟混合料。In recent years,the construction of tunnels has increased day after day.The environment in tunnels is special,and the road surface is flammable and prone to accidents.A kind of environmental flame retardant rubber asphalt mixture was developed and its performance was analyzed with other kinds of mixture.The basic performance of this rubber asphalt mixture is comparable to that of other types of mixture,and it is not easy to deform and crack at high and low temperatures,and it can resist water and load better.In terms of flame retardant and smoke suppression,the environmentally flame retardant rubber asphalt mixture has long ignition time,low quality loss,low flue gas release,and good flame retardant effect.It is a kind of flame retardant smoke suppression mixture with excellent performance for tunnels.
