我们平常所看到的路面改造、路面冷再生都是运用冷再生机的再造技术，在旧沥青道路的基础上，添加一定量的混凝土和粉料，应用再生机对其进行粉碎、加水、搅拌并整形、辗压和维护，促使旧道路可以再次交付使用，由于其能够直接使用原料直接施工，不需要在运送新材料，减少了成本费用缩短施工期因此在路面更新改造方面备受工程项目团队的青睐，下面冷再生机租赁小编带大家一起来看下冷再生机的工程施工前的检测准备工作。

The road surface renovation and cold recycling that we usually see are all using the recycling technology of cold revitalization. On the basis of the old asphalt road, a certain amount of concrete and powder is added, and a recycling machine is used to crush, water, mix and shape, roll and maintain it, so that the old road can be delivered for use again. Due to its ability to directly use raw materials for construction, there is no need to transport new materials, Reduced costs and shortened construction period, therefore, it is highly favored by the engineering project team in the field of road surface renewal and renovation. Below, let's take a look at the pre construction inspection preparation work of the cold recycling machine rental team.

1、旧沥青道路弯沉测试

1. Deflection Testing of Old Asphalt Roads

工程施工前要开展旧路面弯沉检验，不仅为了判定旧路地基承载能力，还为了对再造工程施工后的功效与原道路开展对比分析。

The deflection inspection of the old pavement should be carried out before the construction of the project, not only to determine the bearing capacity of the old road foundation, but also to carry out a comparative analysis of the effect of the reengineering after construction and the original road.

2、检验明确配合比

2. Clear mix proportion inspection

当场铣刨搅拌几段未添加集料和混凝土的旧道路，实验室分别平衡取料开展筛分实验。实验结果应达到：粒径不能超出40mm，粒径为4.75mm的通过率不低于40%，粒径为0.6mm的通过率不低于10%，粒径为0.075mm的通过率宜在3%~20%之间。要是旧料级配不可以满足上述标准时，应添加一定规格、数目的新沥青混合料开展配制。

On the spot, milling and mixing several sections of old roads without adding aggregates and concrete were carried out, and the laboratory balanced the materials for screening experiments. The experimental results should achieve: the particle size should not exceed 40mm, the pass rate should not be less than 40% for particles with a particle size of 4.75mm, the pass rate should not be less than 10% for particles with a particle size of 0.6mm, and the pass rate for particles with a particle size of 0.075mm should be between 3% and 20%. If the grading of the old material cannot meet the above standards, a certain specification and quantity of new asphalt mixture should be added for preparation.

3、试验段工程施工

3. Construction of experimental section engineering

配合比完成后，即可开展试验段工程施工；检验道路长度宜为100m~200m。试验段工程施工应包含以下几点：

After the mix proportion is completed, the construction of the experimental section can be carried out; The length of the inspection road should be between 100m and 200m. The construction of the experimental section project should include the following points:

1）测算每平米混凝土使用量，并明确混凝土放置的纵、横向间隔；

1) Calculate the amount of concrete used per square meter and clarify the vertical and horizontal spacing of concrete placement;

2）冷再生机的工作主要参数：铣刨、粉碎的深度；行驶的速度；刀具的转速等；

2) The main working parameters of the cold regeneration machine include the depth of milling and crushing; The speed of travel; The speed of the cutting tool, etc;

3）再生机每行驶1米的需水量及供水车的总数；

3) The water demand for every 1 meter of operation of the regeneration machine and the total number of water supply vehicles;

4）压实工艺主要参数：机械设备组成；压路机的规格型号、辗压遍数、辗压速度；辗压时水分含量的容许误差；

4) Main parameters of compaction process: composition of mechanical equipment; The specifications and models of the roller, the number of rolling passes, and the rolling speed; The allowable error of moisture content during rolling;

5）优化方案后的施工组织方案及工艺等。

5) The optimized construction organization plan and process, etc.

以上就是关于冷再生机在对旧道路改造前的准备检车工作，只有事前将路段的检测和试验段施工工作做到位，才能对需要施工路面有一个数据的了解，从而在施工的时候对症下药，有针对性的实施冷再生改造施工，才能使得改造后的沥青道路的质量和品质得到保障。更多相关事项就来我们网站http://www.tclqgc.com咨询！

The above is about the preparation and inspection work of the cold recycling machine before the renovation of the old road. Only by doing a thorough inspection of the road section and the construction of the test section in advance can we have a data understanding of the road surface that needs to be constructed, so that the targeted implementation of cold recycling renovation construction can ensure the quality and quality of the modified asphalt road.
