背景资料
某公路工程项目,路线长36.2km,双向4车道,路幅宽24.5m,设计车速80km/h,路面基层为水泥稳定土基层,根据工程实际情况及施工单位人力、设备条件,施工单位采用了路拌法水泥稳定土基层施工工艺。摊铺水泥日进度1.6km(单向),K6+200~K10+900路段具体施工过程如下:
(1)施工放样,恢复中线;根据施工布料需要在下承层上画布料网络。
(2)对水泥稳定土基层施工所需的土料、集料、水泥等按要求进行备料。
(3)确定松铺系数后,施工单位共用5d时间完成摊铺土任务。某日摊铺土2.5km。
(4)按规定洒水闷料,整平轻压。
(5)按规定摆放水泥,用刮板将水泥均匀摊开。
(6)为保证拌和质量,按规定采用了稳定土拌和机进行拌和。为了避免损坏下承层,拌和深度保持在下承层顶面5~10mm。
(7)拌和料拌和均匀后,立即用平地机初步整形,为保证整形质量,全路段平地机均由两侧路肩向路中心进行刮平。
(8)整形后,当混合料的含水率为最佳含水率(±1%~±2%)时,按规定用轻型压路机配合12t以上的压路机进行碾压。直线和平曲线段,由两侧路肩向路中心碾压,设超高的平曲线段,由外侧路肩向内侧路肩碾压。
由于部分工程量无法准确确定,业主和施工单位采用单价合同签订施工合同,业主委托甲监理公司进行施工监理,工程计量方式为监理工程师与施工单位联合计量。
问题:

本项目路拌法水泥稳定土基层施工准备中少了什么重要环节?并简述这一环节的主要工作。
