摘　　要：针对泡沫沥青稳定旧路面材料铺筑技术,采用工程实例结合理论实践的方法,先分析了泡沫沥青的相关概念和优势,接着探讨了原路面铣刨施工的要求,然后提出泡沫沥青稳定旧路面材料铺筑技术的应用过程,最后提出几点心得体会。分析结果表明,在旧路面施工中,采用泡沫沥青稳定材料,可实现沥青混合料的重复再利用,而且施工效率比较高,可在原路面上施工,节省基层开挖、回填、碾压的工序,具有良好的经济效益和社会效益,值得在旧路面改造和升级中推广和应用。Aiming at paving technology of foamed asphalt to stabilize old pavement materials,combined with theoretical practice,engineering examples are used to first analyze the related concepts and advantages of foamed asphalt,and then the requirements for milling and planing of the original pavement are discussed,and application process of paving technology of foamed asphalt stabilizing old pavement materials is proposed,finally a few thoughts and experiences are put forward.The analysis results show that in the construction of the old pavement,the use of foamed asphalt stabilizing material can realize repeated reuse of the asphalt mixture,the construction efficiency is relatively high,and it can be constructed on original pavement,which omits the processes of foundation excavating,refilling and rolling.The process has good economic and social benefits and is worthy of popularization and application in the reconstruction and upgrading of old roads.
