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。水的輸送量通過微處理器控制的泵送系統精 確控制。銑刨轉子將水與銑刨料充分拌和均勻。

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.

液體穩定劑，例如熱瀝青（冷再生機可選配乳化瀝青噴灑裝置）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。

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。此技術在上世紀五十年代開始在歐美等得到應用，目前已是發達已獲得較為普遍的應用，并常常作為路面維修的方案。

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.
