12、。标段路线长度为3.1KM。老路路基标准横断面宽24.5M,本次扩建后路基标准宽度为41.0 ,即由四车道扩建为八车道。2、 区内地质本工程地处珠江三角洲腹地,地势平坦,鱼塘遍布,全线大部分为柔弱的淤泥、淤泥质土上填方路基,局部路基地段存在膨涨土。3、 软土地基设计原则对于一般的膨涨土路段,采用超挖80cm,换填泥灰结碎石80cm处理。本标段换填泥灰结碎石工程量为5896立方米。4、 技术参数根据水泥混凝土路面施工及验收规范(GBJ97-870)要求,泥灰结碎石严格控制泥灰含量。石、灰的总含量不大于总混合料的20,本次试验路段根据规范要求选定配合比为:石灰、碎石、土分别占混合料总重的2、18、
13、80。土的塑性指数宜为1027的粘性土,粗碎石的粒径宜小于或等于40mm。每层摊铺厚度为2025 cm。试验段位置选在K20+765K21+040段左侧,试验路段全长为275M。5、 泥灰结碎石施工方法5.1、试验路段施工目的本次试验路段是根据拟定的施工配比及工艺技术要求进行,试验路段施工目的:按拟定好的施工方案进行施工填筑,检查拟定的施工配比及工艺技术要求是否满足设计及规范要求。5.2、施工工艺泥灰结碎石施工工艺见下图:泥灰结碎石施工工艺框图施工准备整平地面测量放样划方格线泥灰结碎石摊铺机械碾压路面整平最终碾压土的塑性指数检验泥灰结碎石制备运输配合比设计 说明: 1、每层摊铺厚度为2025c
