底基层混合料拌合
Mixing of subbase mixture
根据批复的济南水稳砼底基层配合比确定各种材料的比例，采用拌合机进行拌合。拌合前先检测场内各规格集料的含水率，并计算当天的施工配合比，实际生产配合比的拌和含水率应较佳含水率大于0.5%～1%，以补偿摊铺及碾压过程中的水分损失。
The proportion of various materials shall be determined according to the approved mix proportion of Jinan water stabilized concrete subbase, and the mixer shall be used for mixing. Before mixing, the moisture content of aggregates of various specifications in the site shall be tested first, and the construction mix proportion of the day shall be calculated. The actual production mix proportion shall have a better moisture content of more than 0.5%~1% to compensate for the moisture loss during paving and rolling.
拌和站现场安排两名试验人员随时进行检测。每天开机后当集料输送带上的集料达到正常状态时，立即从集料带上截取一段集料进行级配试验，检查施工级配配合比是否满足要求。
Two test personnel shall be arranged at the mixing plant site to conduct inspection at any time. When the aggregate on the aggregate conveyor belt reaches the normal state after starting every day, immediately cut a section of aggregate from the aggregate belt for grading test to check whether the construction grading mix ratio meets the requirements.
正式生产之后，每1-2小时检查一次拌和情况，检验其配合比、含水率、水泥剂量，发现异常时及时调整或停止生产。
After formal production, check the mixing condition every 1-2 hours, check the mix ratio, water content and cement dosage, and timely adjust or stop production in case of any abnormality.
拌合时水泥实际用量要比设计用量稍有增加，且增加值不超过0.5%，以抵消施工强度离散性比设计强度离散性增大的影响。加水量的计量采用流量计的方式，且流量数值要在中央控制室的控制面板上显示。
The actual cement consumption during mixing is slightly higher than the design consumption, and the increase value is not more than 0.5%, to offset the impact of the increase in the construction strength dispersion than the design strength dispersion. The metering of water addition shall adopt the flow meter, and the flow value shall be displayed on the control panel in the central control room.
在每天施工结束后要清理干净，检查并进行适当维护，尤其要注意避免水泥结块而堵塞水泥下料口，防止生产过程中混合料水泥剂量偏低，影响基层强度。
Clean up, inspect and maintain properly after the construction every day, especially pay attention to avoid cement caking and blocking the cement blanking port, and prevent the low cement dosage of the mixture in the production process from affecting the strength of the base course.
底基层混合料运输
Transportation of subbase mixture
运输采用大吨位自卸汽车，汽车的尾部尺寸符合摊铺机喂料斗的要求，运输能力要与拌合楼产量和现场摊铺能力相匹配。运输车辆在装料时应派专人指挥前后移动，先装前部，再装后部，后再装中间，防止出现混合料离析现象。
The large-tonnage dump truck shall be used for transportation. The tail size of the truck shall meet the requirements of the paver's hopper. The transportation capacity shall match the production of the mixing plant and the on-site paving capacity. When loading, transport vehicles shall be directed to move forward and backward by specially-assigned person. The front part shall be loaded first, then the rear part, and then the middle part to prevent mixture segregation.
混合料运输车装料前应清理干净，车厢不得有杂物。运输时采用苫布全封闭覆盖混合料，以防止水分蒸发及沿途污染。
The mixture transport vehicle shall be cleaned before loading, and the carriage shall be free of sundries. The mixture shall be covered with tarpaulin completely during transportation to prevent water evaporation and pollution along the way.
车辆按规定线路行驶，不得在养生期间的铺筑层行使，车辆行走速度不宜太快，保证运输安全。混合料要尽快运至铺装现场，保证及时、连续和安全。车辆倒车时在摊铺机前30cm处停住，卸料时挂空挡，注意不要撞击摊铺机，不要把料卸在摊铺机外面。
The vehicle shall be driven according to the specified route and shall not be driven on the pavement during curing. The vehicle shall not travel too fast to ensure transportation safety. The mixture shall be transported to the paving site as soon as possible to ensure timely, continuous and safe. When backing up, the vehicle shall stop 30cm in front of the paver. When unloading, the vehicle shall be in neutral gear. Pay attention not to hit the paver, and do not unload the material outside the paver.
在进入施工区域的路基坡道口铺设草帘及土工布，防止运输车辆将泥带入工作区域，同时安排专人随时打扫车轮印记，确保下承层及已铺筑的下基层面干净。还有什么产品事项了解可以随时来我们网站http://www.ycgjglcl.com进行咨询！
The grass curtain and geotextile shall be laid at the roadbed slope crossing entering the construction area to prevent the transport vehicles from bringing mud into the working area. At the same time, special personnel shall be arranged to clean the wheel marks at any time to ensure that the lower bearing layer and the paved lower base surface are clean.
