阻燃沥青混合料在高速公路长大隧道面层施工中的应用

Application of Flame Retardant Asphalt Mixture in Surface Construction of Expressway Long-Large Tunnel

结合福建某条高速公路相关工程实例,分析阻燃剂对混合料的性能影响及施工控制。试验结果表明,阻燃剂对改性沥青针入度、延度、软化点及混合料具有一定的影响,但总体上对沥青及沥青混合料影响没有超出规范要求。

Combined with the practice of an expressway in Fujian, this paper discusses the effect on the performance of mixtures by flame retardant and construction control. The test results show that flame retardant has some effects on penetration, ductility, softening point and mixture of modified asphalt, but the effects in general are not beyond the requirements of the specifications.
