济南路面工程施工家好

　　为了准确确定旧路沥青层厚度、基层材料和基层厚度，可以通过现场冷再生技术对旧路结构材料进行破碎取样，掌握结构强度。为了确定添加剂的类型和数量，必须详细分析旧道路结构材料的土壤质量。

　　In order to accurately determine the thickness of asphalt layer, base material and base layer of the old road, it is possible to break and sample the old road structural materials through the cold recycling technology on site to master the structural strength. In order to determine the type and quantity of additives, the soil quality of old road structural materials must be analyzed in detail.

路面改造工程冷再生施工技术

　　3 cold regeneration construction technology of pavement reconstruction project

　　(1)试验段施工。通过试验段的施工，可以验证施工数据，确定合理的配合比。选定的试验路段路面被压碎并取样后，进行施工。施工过程中，人员记录各种参数和存在的问题。在试验段施工过程中，通过多次试验确定了更佳参数。试验段施工完成后，对施工中出现的问题进行分析研究，并探索相应的解决方法，以避免正式施工中出现类似问题。

　　(1) Test section construction. Through the construction of the test section, the construction data can be verified and the reasonable mix proportion can be determined. After the pavement of the selected test section is crushed and sampled, the construction shall be carried out. In the process of construction, professionals record various parameters and existing problems. In the construction process of the test section, the best parameters are determined through many tests. After the completion of the construction of the test section, analyze and study the problems in the construction, and explore the corresponding solutions to avoid similar problems in the formal construction.

　　(2)摊铺作业。首先是粗骨料的摊铺作业。根据相关标准和试验段提供的数据，合理确定粗骨料的用量，确保70%的旧路面覆盖均匀。其次，采用正方形网格法铺水泥。在此过程中，水泥用量保持在5%范围内，实际水泥用量根据再生层厚度确定。为摊铺的均匀性，避免出现网格空白或水泥堆积的现象。在水泥摊铺过程中，人工摊铺与冷再生机保持一定的距离，并根据冷再生机的运行速度合理调整摊铺进度，避免水泥初凝摊铺时间过长，不仅延误施工进度，而且影响现场冷再生技术的施工质量。

　　(2) Paving operation. The first is the spreading of coarse aggregate. According to the relevant standards and the data provided by the test section, the amount of coarse aggregate shall be reasonably determined to ensure that 70% of the old pavement is covered evenly. Secondly, the square grid method is used to pave cement. In this process, the cement consumption is kept within 5%, and the actual cement consumption is determined according to the thickness of regeneration layer. In order to ensure the uniformity of paving and avoid the phenomenon of blank grid or cement accumulation. In the process of cement paving, keep a certain distance between manual paving and cold recycling, and reasonably adjust the paving progress according to the operation speed of cold recycling machine to avoid the long time of cement initial setting paving, which not only delays the construction progress, but also affects the construction quality of cold recycling technology on site.
