再生旧沥青混合料用做柔性基层研究

Study of Regenerated Old Asphalt Mixture Used for Flexible Base

旧沥青混合料的再生利用可以节省建设投资,保护环境,文中介绍了旧沥青混合料残余性能的评价方法,冷拌结合料乳化沥青和稳定剂的选择。通过工程实例探讨了再生料用做柔性基层配合比设计的方法、原则,铺筑的施工工艺及其路用性能的检测跟踪。

The regenerating utilization of the old asphalt mixture can save the construction investment and protect the environment. The article introduces the evaluation method of the surplus performance of old asphalt mixture, the emulsified asphalt of cold mixture and the selection of stabilizing agent. Through the engineering example, it is to approach the method and principle of the mixture ration design of the regenerated mixture used for the flexible base, and the paving construction process and the measurement track of the road using performance.
