（1）根据原道路再生深度内的平均密度，计算每平米新料的添加量。

(1) Calculate the amount of new material added per square meter based on the average density within the regeneration depth of the original road.

（2）根据每车料的质量或体积，计算每车料的堆放距离。

(2) Calculate the stacking distance of each vehicle based on its mass or volume.

（3）采用人工摆放和摊铺水泥，应根据水泥用量3.9%,计算每水泥稳定层需要的水泥用量17.4kg,确定水泥摆放的纵横间距。

(3) Using manual placement and paving of cement, the cement dosage required for each square meter of cement stable layer should be calculated based on 3.9% of the cement dosage, and the vertical and horizontal spacing of cement placement should be determined.

冷再生机行进速度应根据路面损坏状况和冷再生深度进行调整，一般为5m/min~7m/min,使得铣刨后料的级配波动范围不大。应根据道路两侧设置的水平控制桩，定期核查再生深度是否正确，如冷再生深度超过设计深度±1cm,应查明原因后再继续施工。冷再生机后应有专人进行质量控制，随时检查再生深度、水泥含量和含水量，并配合再生机操作员进行调整。

The travel speed of the cold recycling machine should be adjusted based on the damage condition of the road surface and the depth of cold recycling, generally ranging from 5m/min to 7m/min, so that the fluctuation range of the material grading after milling is not large. Regular verification of the correct regeneration depth should be carried out based on the horizontal control piles set on both sides of the road. If the cold regeneration depth exceeds the design depth by ± 1cm, the cause should be identified before continuing construction. After the cold regeneration machine, there should be a dedicated person for quality control, who should check the regeneration depth, cement content, and water content at any time, and cooperate with the regeneration machine operator to make adjustments.

冷再生机租赁厂家再来讲讲试验段施工：

Let's talk about the construction of the experimental section again from the rental manufacturer of the cold regeneration machine:

（1）根据经验和所用冷再生机械的特点，按6m/min再生机行进速度和转子速度的组合方案对旧路进行铣刨，取铣刨后具有代表性的材料送往试验室进行筛分，级配已接近理想级配。

(1) Based on experience and the characteristics of the cold recycling machinery used, the old road was milled using a combination plan of 6m/min recycling machine travel speed and rotor speed. After milling, representative materials were sent to the laboratory for screening, and the grading was close to the ideal grading.

（2）按照室内试验结果，在旧路上摊铺新加料或填料，但不添加稳定剂，按（1）确定的方案进行铣刨，取铣刨后具有代表性的材料样品送往实验室进行筛分，如果筛分后的级配与室内设计级配超过允许波动范围，应调整再生机速度和转子速度，使铣刨后的级配与室内设计级配相比波动在允许范围内。

(2) According to the indoor test results, pave new materials or fillers on the old road without adding stabilizers, and carry out milling according to the scheme determined in (1). Take representative material samples after milling and send them to the laboratory for screening. If the grading after screening exceeds the allowable fluctuation range compared to the indoor design grading, adjust the speed of the regeneration machine and rotor to ensure that the grading after milling fluctuates within the allowable range compared to the indoor design grading.

（3）根据稳定剂类型，采用1~3种压实方案进行施工（包括压路机吨位、碾压顺序、遍数等），以确定为合理的碾压方案。

(3) According to the type of stabilizer, 1-3 compaction schemes are used for construction (including roller tonnage, compaction sequence, number of passes, etc.) to determine the reasonable compaction scheme.

（4）取冷再生机经铣刨、拌和后的混合料，送往试验室，对以水泥作为稳定剂的冷再生，测定冷再生混合料的含水量、水泥量，并按公路工程无机结合料稳定材料试验规程要求成型试件，测定其7d无侧限抗压强度。

(4) Take the mixture from the cold recycling machine after milling and mixing, and send it to the laboratory. For the cold recycling mixture with cement as the stabilizer, measure the water content and cement content of the cold recycling mixture, and shape the test piece according to the requirements of the test code for inorganic binder stabilized materials in highway engineering, and measure its 7-day unconfined compressive strength.

（5）对试验段的弯沉、压实度、平整度、厚度、宽度等指标进行检测。

(5) Inspect the deflection, compaction, flatness, thickness, width and other indicators of the experimental section.

根据试验段的结果确定冷再生混合料的级配、施工时采用的再生机行进速度、转子速度及再生结构压实工艺。更多相关事项就来我们网站咨询了解！
