沥青路面冷态修补技术（乳化沥青混合料）研究-道路与铁道工程专业论文.docx

摘要通过对乳化沥青乳化机理的分析，证明复合乳化剂比单一乳化剂效果好。 摘要 通过对乳化沥青乳化机理的分析，证明复合乳化剂比单一乳化剂效果好。 在大量试验的基础上研制了几种复合乳化剂，并确定了各复合乳化剂的最佳配 比。复合乳化沥青能够满足工程施工的要求，破乳速度可调，解决了工程上乳 化沥青混合料破乳太快的问题。同时，还对乳化沥青的性质进行了探讨，特别 是乳化沥青的结皮现象、蒸发残留物性质等。 由于乳化沥青混合料在沥青路面修补中的独特优势，本文对乳化沥青混合 料的组成结构、强度机理进行了分析。在通用的修正马歇尔试验方法基础上， 进行了再次修正和补充，提出了针对水泥一乳化沥青混合料的再修正马歇尔试 验方法；提出了新的乳化沥青混合料初始强度、工作性、成型强度、水稳性的 试验方法、评价指标与技术标准；最终提出乳化沥青混合料和水泥一乳化沥青 混合料综合配合比设计方法和技术标准。 最后对乳化沥青混合料的经济与社会效益进行了分析。 关键词：乳化沥青 复合乳化剂 乳化机理 乳化沥青混合料 水泥一乳化沥青混合料 经济与社会效益 AbstractThrough Abstract Through the analysis of asphalt emulsification mechanism，it is proved that the composite emulsifier has better effects than single emulsifier．Some composite emulsifier has been made out after a great deal of experiments，and the best．composite proportion of the composite emulsifiers was confirmed．Composite emulsified asphalt can meet the requirements of site application．Its breaking speed earl be adjusted，then solves the trouble of breaking too quickly of emulsified asphalt mixture in construction．At the same time，the characteristics of emulsified asphalt have been studied． Because of its own special advantages in patch of asphalt pavement，the article analyzes the composition structure and strength mechanism of emulsified asphalt mixture．It was supplemented and corrected to the current corrected Marshall experiment method．It proposed re—corrected Marshall experiment method for cement—emulsified asphalt mixture，and it proposed evaluation methods and evaluation guideline and standard on the initial strength、Workability、Formed strength and Water stability through a lot of experiments．At last，it proposed the comprehensive mix design of emulsified asphalt mixture and cement—emulsified asphalt mixture and proposed technical standard ofemulsified asphalt mixture． n also analyzed the economical and social results ofemulsified asphalt mixture Key words：Emulsified asphalt Composite emulsifier Emulsification mechanism Emulsified asphalt mixture Cement—emulsified asphalt，mixture Economical and social
