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.

冷再生機的工作裝置是安裝有大量專用銑刨刀的銑刨拌和轉子。機器在舊路面上沿工作面行駛，轉子下降到設定深度，高速旋轉，銑刨并破碎拌和原路面材料（包括面層和基層），同時噴水系統根據行駛速度及銑刨深度，從伴隨的水車中抽水，向工作裝置罩殼內自動噴灑定量的水。

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.

水的輸送量通過微處理器控制的泵送系統控制。銑刨轉子將水與銑刨料充分拌和均勻。液體穩定劑，例如熱瀝青可通過專門設計的噴嘴將乳化瀝青噴灑到工作裝置罩殼內；粉狀穩定劑，如水泥，可按設計添加量事先撒布在再生機工作面上，再生機將粉狀穩定劑與路面和水一次性破碎并拌和均勻。

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.

就地冷再生技術不僅適用于高等級公路的維修與改造，也適用于一般道路及鄉間公路的維修與改造。近幾年來，就地冷再生技術在我國受到了業內人士普遍的關注與認同，推廣普及速度很快，例如遼寧、吉林及河北等地區已經應用相當普遍，并且取得了良好的社會及經濟效果。

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.
