| 摘 要： | 1 IntroductionDesign Specifications ofHighway Tunnel(JTG D70-2004)1]specifies that all the highway tunnels may useconcrete pavement . When necessary the flame-retardedasphalt pavement may be used.The article explains whyall the accidents in Zhejiang highway tunnel occurred inconcrete pavements instead of in asphalt pavements .It isbecause the concrete pavement’s anti-skid coefficient andthe friction force decreased speedy. In addition, com-pared with concrete pavements ,the asphalt pavem…

| Abstract: | Used as flame returdant of tunnel asphalt pavement, organic bromides produce a large amount of poisons and smoke in construction and flame retardation stage. The alkaline filler was found to replace mineral filler, and the flame- retarded asphalt mixtures were produced. Experimental results show that these asphalt mixtures are smoke restrained ; the performances and construction technology of asphalt pavement are not influenced; also the alkaline filler is of low-price. So this kind of flame-retarded asphalt mixtures is suitable for tunnel patement. |
