某城市主干路道路工程地质条件良好,地下水埋深在12m以下。施工道路部分通过农田,部分位于现况路上。为保证路基稳定,必须置换腐殖土,刨除旧路,采用塑性指数10~18的素土填筑。碾压密实。设计的路面底基层、基层结构是:12%石灰土基底层30cm,石灰粉煤灰砂砾基层40cm.无机结合料稳定材料不允许现场拌合。
问题:
控制石灰粉煤灰砂砾基层施工质量的要点有哪些?
(1)石灰粉煤灰砂砾基层是该路的承重层。根据背景条件,该路的石灰粉煤灰砂砾基层所处的工程条件较理想,重点在该基层自身质量控制。要使材料强度达标,即主干路R7为0.8~1.1MPa.首先一个要点应注意基层原材料,应采用符合质量要求的石灰、粉煤灰、砂砾。
(2)应注意配合比。必须掌握该材料中的石灰、粉煤灰含量及混合料的最佳含水量和最大干密度等质量要素及相互间的关系。
(3)城市道路中的无机结合料稳定材料必须工厂化集中拌合。为保证质量,应注意使用不同原材料均需分开堆放、防雨,严格控制含水量、运输及混合料堆放时间要求。
(4)注意摊铺碾压环节。摊铺时掌握摊铺杜铺系数,碾压时掌握最佳含水量(±1%~±2%)和机型配套、碾压工艺等。
(5)注意养生期控制要求。
(6)注意质量控制全过程的质量检验报告,不要缺项。
