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 of aircraft models that have been used in developed regions in Europe and America. The high price of imported aircraft 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。水的输送量通过微处理器控制的泵送系统精 确控制。铣刨转子将水与铣刨料充分拌和均匀。

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. The water delivery is precisely controlled by a microprocessor controlled pumping system. The milling rotor fully mixes the water with the milling material.

液体稳定剂，例如热沥青（冷再生机可选配乳化沥青喷洒装置）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。

Liquid stabilizer, such as hot asphalt (cold recycling machine can be equipped with emulsified asphalt spraying device), 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。此技术在上世纪五十年代开始在欧美等得到应用，目前已是发达已获得较为普遍的应用，并常常作为路面维修的方案。

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. This technology began to be applied in Europe and the United States and other countries in the 1950s. At present, it has been widely used in developed countries and is often used as a pavement maintenance scheme.
