本文以宝山海江路泡沫沥青厂拌冷再生试验路为例,介绍了泡沫沥青冷再生混合料的性能特点,探讨了泡沫沥青混合料的实验室设计方法,并对设计材料的有关性能进行了分析和比较,认为该材料可以达到粗粒式沥青混凝土的有关性能,用其替代原沥青路面的下面层和部分基层,不仅可以对原路面结构上补强,而且还可以充分利用路面铣刨料,保护环境,节省维修费用。最后,对泡沫沥青厂拌冷再生混合料的生产和施工工艺进行了介绍。
In this paper, Baoshan Hajiang Road, foam asphalt plant cold regeneration test road as an example, introduced the characteristics of foam asphalt cold recycled mixture, explored the foam asphalt mixture laboratory design method, and the design of the relevant properties of the material were analyzed And compared that the material can achieve the relevant performance of coarse-grained asphalt concrete, with its replacement of the original asphalt pavement and some of the grass-roots level, not only on the original road surface reinforcement, but also can make full use of road milling material, Protect the environment, save maintenance costs. Finally, the production and construction technology of foam asphalt plant mixed with cold recycled mixture are introduced.
