对于公路项目施工而言，采用水泥稳定碎石技术，其主要原理为根据一定比例混合碎石、凝胶与灰浆等材料，采用嵌挤与压实相结合的原理进行压实，对出现的孔隙采用足量的灰浆与细集料填充。那么公路施工中应用水泥稳定碎石的相关准备工作怎么样呢？
For the construction of highway projects, the cement stabilized macadam technology is adopted. Its main principle is to mix macadam, gel and mortar in a certain proportion, and use the principle of combination of embedment and compaction to compact. The pores that appear are filled with sufficient mortar and fine aggregate. How about the preparation work related to the application of cement stabilized macadam in highway construction?
在公路施工项目应用水泥稳定碎石前，要认真检查项目基层施工质量是否达标，一旦施工质量不符合标准，直接影响到项目整体施工质量。项目基层施工质量检测主要包含：检查其宽度、平整度、坡度、压实状况及外观等，必须要符合要求规定，以此提高基层施工质量。
Before applying cement stabilized macadam in highway construction projects, it is necessary to carefully check whether the construction quality of the project base meets the standard. Once the construction quality does not meet the standard, it will directly affect the overall construction quality of the project. The quality inspection of project base construction mainly includes: checking its width, flatness, slope, compaction condition and appearance, which must meet the requirements, so as to improve the quality of base construction.
在公路工程施工中，施工前期准备与放样同等重要，采用全站仪设备测定路面中线，分别在直线段/20m与曲线段/10m处设置木桩，在距路边缘外侧半米位置设置指示桩，便于项目进行水平策略，同时选用红漆进行标注，并在红漆涂刷位置增加钢丝绳，根据施工现场实际环境与路面设计方案，准确设计路面边线。
In the construction of highway engineering, the preparation in the early stage of construction is as important as setting out. The total station equipment is used to measure the center line of the pavement. Wooden piles are set at the straight section /20m and curve section /10m respectively, and indicator piles are set at the position half a meter away from the outside of the road edge to facilitate the horizontal strategy of the project. At the same time, red paint is selected for marking, and steel wire rope is added at the position where red paint is painted. According to the actual environment of the construction site and the pavement design scheme, Accurately design the pavement sideline.
水泥稳定碎石被应用于实际施工中前，要确保其配置的合理性，通常采用稳定土厂拌合设备与方法相结合，严格依照实验配比选用配料配置水泥稳定碎石。由于这一过程中水分会损失，因此在方案设计中，含水量要高出佳量0.5~1%，但水泥剂量不能改变。
Before the cement stabilized macadam is applied in the actual construction, it is necessary to ensure the rationality of its configuration. Usually, the mixing equipment and method of the stabilized soil plant are combined, and the ingredients are selected and configured in strict accordance with the experimental proportion. Due to the loss of water in this process, in the scheme design, the water content should be 0.5~1% higher than the optimal amount, but the cement dosage cannot be changed.

采用拌合机调配这些混合原材料，保证配置标准，达到无花面、花团及灰条。待这些混合物材料拌合完成后，要及时去除其中含有的粗细颗粒物，如果情况不理想，则要进行二次拌合，直到达到标准后方可及时将其运输至施工现场，并进行摊铺与压实施工工艺。
The mixing machine is used to mix these mixed raw materials, so as to ensure the configuration standard and achieve no flower surface, flower ball and ash strip. After the mixing of these mixture materials is completed, the coarse and fine particles contained in them should be removed in time. If the situation is not ideal, the second mixing should be carried out, and they can be transported to the construction site in time until they meet the standard, and the paving and compaction construction process should be carried out.
济南水泥稳定碎石厂家提醒大家，必须要注意的是，在拌合物运输中要均匀装载，根据实际情况合理选择运输车辆。一般，水泥稳定碎石从拌合-摊铺-压实，整个过程不超过3h，特别是要低于拌合物终凝固实践，因此自卸运输车为合适，此外在运输中要在混合物上覆盖塑料薄膜，以防水分蒸发。
Jinan cement stabilized macadam manufacturer reminds everyone that it must be noted that the mixture should be evenly loaded during transportation, and the transportation vehicles should be reasonably selected according to the actual situation. Generally, the whole process of mixing paving compaction of cement stabilized macadam shall not exceed 3h, especially lower than the final setting practice of the mixture. Therefore, dump trucks are suitable. In addition, plastic films shall be covered on the mixture during transportation to prevent evaporation.
