摘　　要：现有的沥青路面冷再生技术将回收的旧沥青混合料破碎、筛分后作为集料使用。其中的沥青未得到利用,造成了大量沥青资源的浪费。回收沥青混合料的常温乳化再生技术能充分利用回收混合料中的老化沥青,降低新添加沥青的用量,提高混合料的路用性能。该成果的推广应用将节约大量宝贵的沥青资源,降低材料成本,节约工程投资。为实践"资源节约,环境友好"和可持续发展的交通建设模式做出贡献。In the existing technology of cold asphalt pavement recycling, it is only the aggregate that is used again after the crushing and screening of the Reclaimed Asphalt Pavement （ RAP）, but the asphalt is discarded. So a lot of asphalt resource is wasted. The technology of emulsification and recycling of RAP in room temperature reuses the aged asphalt in the RAP thereby effectively reducing the quantity of newly added asphalt and also improving the performance of the mixture. The application of this technology will save a lot of valuable resources, reduce material costs and save project investments. The technology also contributes to the practice of ＂resource-saving and environmental-friendliness＂ in road construction.
