There is no regional restriction on the construction technology of cold recycling machine, which can be used in asphalt pavement all over the country. According to the calculation, if popularized, a prefecture level city should be equipped with 3-5 sets. There are many reasons for the low domestic ownership. The high price of imported models should be one of the main reasons.

冷再生机的工作装置是安装有大量专用铣刨刀的铣刨拌和转子。机器在旧路面上沿工作面行驶，转子下降到设定深度，高速旋转，铣刨并破碎拌和原路面材料（包括面层和基层），同时喷水系统根据行驶速度及铣刨深度，从伴随的水车中抽水，向工作装置罩壳内自动喷洒定量的水。

The working device of the cold recycling machine is a milling rotor equipped with a large number of special milling cutters. When the machine runs along the working face on the old road, the rotor descends to the set depth, rotates at high speed, Milles and mixes the raw pavement materials (including surface course and base course). At the same time, the water spraying system pumps water from the accompanying water truck according to the driving speed and milling depth, and automatically sprays a certain amount of water into the working device shell.

水的输送量通过微处理器控制的泵送系统控制。铣刨转子将水与铣刨料充分拌和均匀。液体稳定剂，例如热沥青可通过专门设计的喷嘴将乳化沥青喷洒到工作装置罩壳内；粉状稳定剂，如水泥，可按设计添加量事先撒布在再生机工作面上，再生机将粉状稳定剂与路面和水一次性破碎并拌和均匀。

The water delivery is controlled by a microprocessor controlled pumping system. The milling rotor fully mixes the water with the milling material. Liquid stabilizer, such as hot asphalt, can spray emulsified asphalt into the working device shell through specially designed nozzle; The powdery stabilizer, such as cement, can be spread on the working face of the reclaimer according to the design amount. The reclaimer will crush the powdery stabilizer with the road and water at one time and mix them evenly.

就地冷再生技术不仅适用于高等级公路的维修与改造，也适用于一般道路及乡间公路的维修与改造。近几年来，就地冷再生技术在我国受到了业内人士普遍的关注与认同，推广普及速度很快，例如辽宁、吉林及河北等地区已经应用相当普遍，并且取得了良好的社会及经济效果。

In situ cold recycling technology is not only suitable for the maintenance and reconstruction of high-grade highway, but also suitable for the maintenance and reconstruction of general roads and rural roads. In recent years, in situ cold recycling technology has been widely concerned and recognized by the industry in our country, and the popularization speed is very fast. For example, Liaoning, Jilin and Hebei have been widely used, and achieved good social and economic results.
