摘　　要：采用25%的沥青铣刨旧料掺量,对AC-25C沥青混合料配合比设计进行研究,包括设计级配范围、沥青用量确定方法、性能验证指标等。该材料通过在G15高速公路大修的应用情况可以表明:在高速公路重载环境下应用高性能混合旧料再生利用技术,可实现废弃旧料的大规模高层次的再生利用。性能指标均满足设计要求,对节约工程造价,节能减排绿色利用起到了积极作用。This paper studied a mix design method of the AC-25C asphalt mixtures with 25% asphalt milling material content. This study included the aggregate gradation design, the asphalt ratio design, and the road performance evaluation. The application of the material on the overhaul of the G15 expressway showed that under the heavy-load environment of the highway, this technology can realize large-scale and high-level recycling of old waste materials. The road performance of this material meet the design requirements and shows benefits saving project cost, energy saving and emission reduction and green utilization.
