水泥稳定碎石底基层、基层技术交底记录.doc

交底内容：
1、路槽验收
    路槽整理成形后，对压实度、高程、平整度、宽度、横坡度等要经监理工程师验收合格后方可进行下步工序施工。
 2、施工放样
   采用拓普康全站仪放出控制点，用经纬仪加密，每隔10米打出中心桩和边桩，在设定桩位处钉设钢钎，测定高程，挂好施工线。
3、水泥碎石拌和
混合料的拌和采用集中拌和，在正式拌和前，先调试所用的厂拌设备，从表盘、水箱、水泥灌、各下料仓、皮带输送机、空压机、出料仓到各部位线路均调到最佳状态，然后按试验配合比进行试拌，确定施工配合比。
4、运输和摊铺
（1）、运输：混合料的运输一律采用箱板密封良好的10T以上的自卸汽车，其车箱底始终保持洁净。
（2）、摊铺：
5、碾压遍数：先用振动压路机稳压2遍，再振压4遍，再静压2遍。
6、养生
水泥碎石碾压完成后，立即覆盖草席洒水养护。养生期
