摘要
在现有乳化沥青冷再生沥青混合料配合比设计方法的基础上,介绍了乳化沥青混合料强度形成过程,结合某养护改善工程的实际情况,对规范中要求的二次成型的设计方法与一次成型方法进行了论证分析,提出了二次成型设计方法的差异性与不足,并通过施工过程中现场机械的碾压成型方案进一步论证,在此基础上推荐采用旋转压实仪进行设计,乳化沥青再生混合料一次碾压(乳化沥青破乳完成前压实)成型的施工工艺。
On the basis of the present cold recycling mixture design method, this paper introduced the emulsion cold recy- cling mixture strength development mechanism. Based on the practice of an actual emulsion cold recycling project, it ana- lyzed the lab specimen compaction method in once and twice compaction, which found the mixture performance differential. According to the field data that carried on by two types of compaction method, it confirmed the lab study. Furthermore, it proposed the lab gyratory compactor design method, and once compaction technique.
