冷再生工艺有其适用性，先期需进行路面诊断。该工艺只是对于≯25cm的浅层路面结构的再生利用，对路面结构下层的病害没有修复作用，对于路面基层承载力不足，弯沉值过大等情况需要进行深层处理以恢复路面的使用功能，简单的一层冷再生工艺不能起到彻底强化结构层的作用。下面冷再生机租赁厂家为您讲解下相关工艺信息：
The cold regeneration process has its applicability and requires road surface diagnosis in the early stage. This process is only for the regeneration and utilization of shallow pavement structures with a thickness of not more than 25cm, and has no repair effect on the diseases in the lower layer of the pavement structure. For situations such as insufficient bearing capacity of the pavement base and excessive deflection value, deep treatment is needed to restore the functionality of the pavement. A simple one layer cold regeneration process cannot fully strengthen the structural layer. Below, the manufacturer of the cold regeneration machine rental will explain the relevant process information to you:
（1）原材料试验。施工前，用再生机在原旧路面上铣刨有代表性的样品，了解实际结构层厚度和材料类型，为试验室配合比设计提供样品。选取的铣刨料样品应进行下列试验：级配试验、塑性指数、击实试验、含水量。
(1) Raw material testing. Before construction, use a recycling machine to mill representative samples on the original and old road surface, understand the actual structural layer thickness and material type, and provide samples for the laboratory mix design. The selected milling material samples should undergo the following tests: gradation test, plasticity index, compaction test, and moisture content.
施工段落每5检测路面铣刨料的级配、击实试验、随时检测含水量。根据击实试验所取得的大干密度校核车的水泥撒铺量。冷再生底基层压实度检测采用200mm罐砂桶检测，依据击实所得的干密度控制现场压实度。
During the construction section, the grading and compaction test of the road surface milling material should be tested every 5 kilometers, and the water content should be checked at any time. Check the cement spreading amount of the truck based on the high dry density obtained from the compaction test. The compaction degree of the cold recycled subbase layer is tested using a 200mm sand bucket, and the on-site compaction degree is controlled based on the dry density obtained from compaction.
（2）水泥用量的控制。适宜的水泥剂量不仅可以避免因水泥剂量不足而导致的强度不足，而且可以减少因水泥剂量过大而造成的基层应力收缩裂缝现象，延长道路的寿命。
(2) Control of cement dosage. A suitable cement dosage can not only avoid insufficient strength caused by insufficient cement dosage, but also reduce the phenomenon of stress shrinkage cracks in the base layer caused by excessive cement dosage, and extend the service life of the road.
根据厚度、宽度、水泥剂量计算每撒铺水泥用量：1m×1m×厚度×干密度×0.97×水泥剂量;
Calculate the amount of cement spread per square meter based on thickness, width, and cement dosage: 1m × 1m × thickness × Dry density × zero point nine seven × Cement dosage;
（3）标定粉料撒铺车的撒铺量，确定撒铺车的撒铺系数;
(3) Calibrate the spreading amount of the powder spreading vehicle and determine the spreading coefficient of the spreading vehicle;
（4）每2检测撒铺车每平方的撒铺用量;
(4) Detect the spreading amount per square meter of the spreading vehicle every 2 kilometers;
（5）试验室做标准曲线，滴定法控制水泥剂量。
(5) The laboratory makes standard curves and controls the cement dosage using titration method.
