抗滑、阻燃、降噪沥青混合料（AFNA）在隧道路面中的应用

摘要

The large tunnel is the section prone to accident because of the inferior light,closed environment,longitudinal slope and so on,and it has characteristics such as the big engineering difficulty,big investment,big social influence and so on.In order to ensure the traffic safety,the high requirements should be raised for tunnel pavement.Here,the application of the asphalt mixture with the characteristics of sliding resistance,flame retardation and noise reduction in tunnel pavement is introduced combining with some engineering practices.The result shows that the asphalt mixture has good practical value and economic value,and could provide references for similar projects.%大型隧道因为内部光线差,环境相对封闭,纵坡大,为事故多发地段,又有工程难度大、投资大、社会影响大的特点。为保证行车安全,便对隧道路面提出了很高的要求。本文结合工程实例介绍了抗滑、阻燃、降噪沥青混合料（AFNA）在隧道路面中的应用,实践证明抗滑、阻燃、降噪沥青混合料（AFNA）在隧道路面中应用,有较好的实用价值和经济效益,以供同行参考。
