| 摘 要： | 沥青路面再生的关键技术是对老化沥青的再生。从沥青的微观化学结构入手,分析了胶体结构理论中各组成成分对沥青性能的影响,并剖析了沥青的老化机理,从而提出了再生剂性能的技术要求,在分析了再生剂应有的组成成分的基础上试配了RT-A型再生剂并对其性能进行了试验研究,发现其再生效果显著。

| Abstract: | One of the critical technologies of asphalt pavement regeneration is the regeneration of aging asphalt.The effects of asphalt compositions in the colloform texture theory to its performance are analyzed through the microcosmic chemical constitution.The aging mechanisms of asphalt are analyzed and the technical requirements of regenerating agent are put forward.RT-A type regenerating agent is made up and research has been carried out on its performance.The test shows that it has a good regenerating effect. |
