冷再生机对原路面进行旧路材料和水泥充分加水拌和，有关试验人员应立即现场检测含水量，使冷再生的含水量比佳含水量高出1%～2%，以满足水泥水化作用的需要，同时弥补碾压过程中含水量的损失。下面冷再生机租赁厂家就来讲讲冷再生机对原路面进行哪些施工操作。

The cold recycling machine shall fully add water to mix the old road materials and cement on the original pavement. The relevant test personnel shall immediately detect the water content on the site to make the water content of the cold recycling machine 1%~2% higher than the good one, so as to meet the needs of cement hydration, and make up for the loss of water content during rolling. The following is about the construction operation of the cold recycling machine on the original pavement.

拌和时冷再生机行走速度控制在6m/min。水车在冷再生机前面用水带与之相连并同步进行，为冷再生机加水。水车与冷再生机连接拆卸与安装选在每一施工段起点进行。

The traveling speed of the intercooling regenerator shall be controlled at 6m/min. The waterwheel is connected to and synchronized with the water belt in front of the cold regeneration machine to add water to the cold regeneration machine. The connection, removal and installation of the waterwheel and the cold regenerator shall be carried out at the starting point of each construction section.

冷再生混合料拌和均匀后，用压路机排压一遍，速度控制在3km/h。排压过程中若发现含水量不均匀或不平处，应将补料连同其下层混合料一起翻松10em，刮平后再压实，经过排压之后，用平地机按设计高程整平符合设计标准。

After the cold recycled mixture is evenly mixed, it shall be discharged and compacted once with a roller, and the speed shall be controlled at 3km/h. If uneven or uneven water content is found in the process of pressure relief, the supplementary material and its lower layer mixture shall be scarified for 10em, and then compacted after scraping. After pressure relief, the land leveler shall be used to level according to the design elevation to meet the design standard.

（1）碾压组合：碾压遵循先轻后重，先慢后快的原则，先用YZ14振动压路机稳压一遍，压路机压四到五遍，三轮压路机静压两遍，20t胎压路机压两遍。碾压时注意错轴宽度，并由路边向路中心依次碾压，终压之后；冷再生层应平整光滑，表面有水浆渗出，注意终压完成时间不能超过水泥终凝时间。碾压完成后灌砂法测定压实度，保证密实度满足设计要求。

(1) Rolling combination: the principle of "light first, heavy second, slow first, fast second" shall be followed for rolling. First, YZ14 vibratory roller shall be used to stabilize the pressure once, the roller shall be used for four to five times, the three wheel roller shall be used for static pressure twice, and the 20t tire roller shall be used for rolling twice. When rolling, pay attention to the width of the staggered axis, and roll from the roadside to the road center in turn, after the final rolling; The cold regeneration layer shall be flat and smooth, with water oozing from the surface. It shall be noted that the completion time of final compaction shall not exceed the final setting time of cement. After compaction, measure the compactness by sand filling method to ensure that the compactness meets the design requirements.

（2）施工时间控制：试验段施工过程中冷再生机平均速变为6m/min。施工过程中应尽量减少无故停机时间和刮平时间，确保总体上每一段落施工时间在4.5小时以内。

(2) Construction time control: the average speed of the cold regenerator is changed to 6m/min during the construction of the test section. During the construction process, it is necessary to minimize the time of unscheduled shutdown and leveling, and ensure that the construction time of each section is within 4.5 hours in general.

（3）养生：碾压成形四小时后（视气温情况），可以用潮湿的帆布和其他合适的潮湿材料覆盖。在整个养生期间，都应保持覆盖材料处于潮湿状态。也可用水车在冷再生层上直接淋水养护。在七天内禁止放行交通，始终保持表面湿润。

(3) Curing: Four hours after rolling forming (depending on the temperature), wet canvas and other suitable wet materials can be used for covering. During the whole curing period, the covering materials shall be kept in a damp state. Water truck can also be used to directly spray water on the cold regeneration layer for curing. It is prohibited to release traffic within seven days, and the surface shall always be kept wet.
