| 摘 要： | 鉴于水泥存在初凝时间和终凝时间,通过室内延时成型试验方法,分析研究了水泥—乳化沥青混合料适合的成型时间;通过二次击实后,模拟路面实际施工作业,分析二次击实对混合料性能影响及其程度。结果表明:延时成型对水泥—乳化沥青再生混合料性能有一定影响,施工时摊铺与碾压时间在0～3h之间为宜;马歇尔击实方式对水泥—乳化沥青混合料的强度有所破坏;建议实验室马歇尔击实次数应根据集料的情况确定。

| Abstract: | In view of the fact that cement existence prehardening time and final set time, through the time delay formation testing method, analysed the suitable formation time of cement - emulsion asphalt mixture ; Through two time compaction, Simulated actual work of road construction, analysed the influence of two time compaction and the degree. The result indicated： The time delay formation has certain influence to the cement - emulsion asphalt mixture, the spread paving and the roller compaction time between 0 -3h were suitable; Because the Marshall compaction way had destruction to the intensity of cement - emulsion asphalt mixture, Suggested that the number of compaction should be fixed by the situation of the aggregate . |
