城镇水泥混凝土路面施工技术规程
1 总则
为适应城镇道路建设快速发展的需要,提高我省城镇水泥混凝土路面施工技术水平,保证其施工质量,制定本规程。
本规程适用于我省城镇行政区域内新建、改建、扩建的城镇道路水泥混凝土路面工程。大、中型维修的城镇道路水泥混凝土路面工程,工业园区、生活小区、园林等内部道路水泥混凝土路面工程也可参照本规程执行。
水泥混凝土路面的施工应根据合同及设计文件、施工现场所处的气候、水文、地形等环境条件,选择满足质量指标要求、性能稳定的原材料,确定配合比、设备种类和施工工艺,进行详细的施工组织设计,建立完备的施工质量保障体系。混凝土配合比设计应由具有相应试验资质的单位进行。
水泥混凝土路面施工应并积极推广采用经主管部门批准的新技术、新工艺、新材料、新设备。
水泥混凝土路面施工必须文明施工、安全生产,施工人员应有良好的劳动保护。
混凝土路面铺筑期间,应收集月、旬、日天气预报资料,遇有影响混凝土路面施工质量的天气时,应暂停施工或采取必要的防范措施,制定特殊气候的施工方案。
原材料、半成品或成品的质量标准,凡本规程有规定者,应遵照执行;无规定者,应按现行的有关标准执行。
水泥混凝土路面施工除应符合本规程外,尚应符合国家现行有关标准的规定。
2 术语
路基 subgrade
按照路型位置和一定技术要求修筑的带状构筑物。为路面的基础,承受由路面传递下来的行车荷载。
基层 base course
设在面层以下的结构层。主要承受由面层传递的车辆荷载,并将荷载分布到垫层或土基上,当基层分为多层时,其最下面的一层称底基层。
面层 surface course
直接承
