摘要
对符合中石油化工行业送审稿"阻燃道路沥青的技术要求"阻燃沥青标准的阻燃沥青,满足阻燃沥青极限氧指数及阻燃特性评价——锥形量热仪实验的要求,根据隧道环境进行阻燃沥青混合料配合比设计,并对其进行冻融劈裂试验、车辙试验、劈裂疲劳试验、低温性能弯曲试验等,从而对阻燃沥青的使用性能进行评价,分析阻燃沥青的路用性能。
After satisfied to petrochemical industral recommending requirements of falme retardant asphalt pavement binder, requirements for properties of limited oxygen index and flame resistantce evaluationg index by cone calorimeter are essentially satisfied, in order to test mixes for tunnel pavement gradation design, and we completed out such tests including freeze - thaw splitting intensity ratio test, DSR, Rotary Loaded Wheel Tester （ RLWT）, bend and split test at low temperature, etc. The evaluating laboratory performance of flame ratardant asphalt mix are tested and analyzed in this article.
