以国家863项目"抗滑、阻燃、降噪多功能隧道路面结构设计与铺装技术"为依托,以武汉长江隧道工程为背景,研发了沥青路面材料AFNA,在其满足长江隧道路面的"抗滑、阻燃、降噪"使用要求的同时,应用结构与材料功能一体化的思想,通过分析路面面层厚度组合,得出最佳路面面层厚度和面层材料参数,并成功应用于武汉长江隧道。
Based on the national 863 research project,Structure Design and Paving Technology of Anti-skidding Flame-retarded Noise-reducing Asphalt Pavement, analysis the materials performance of the asphalt pavement with the materials of the Anti-skidding Flame-retarded Noise-reducing(AFNA).Verifying AFNA asphalt pavement meet the Yangtze River tunnel pavement function requirement.The optimum thickness of pavement and materials' parameters were gotten through analysis kinds of pavement combination,which is used on Wuhan Yangtze River Tunnel.
