Generally speaking, the pavement subject to heavy traffic for a long time will have subgrade damage. In order to eliminate this damage, the whole pavement needs to be structurally repaired. The road cold recycling machine reuses all the milling materials, and its economic treatment mode makes the cold recycling construction of foamed asphalt become a pioneering solution to achieve the environmental protection and economic role.

組成：路面冷再生機是瀝青路面冷再生施工中的主要設備，一般由動力系統、傳動系統、工作裝置、噴灑系統和操縱控制系統組成。

Composition: pavement cold recycling machine is the main equipment in asphalt pavement cold recycling construction. It is generally composed of power system, transmission system, working device, spraying system and operation control system.

工作原理：路面冷再生機向前行進時，轉子向上旋轉銑刨原路面材料，同時，水通過軟管從路面冷再生機連接的水車中輸送過來，并在路面冷再生機的拌和倉中噴灑。水的輸送量通過微處理器控制的泵送系統準確控制，以達到需要的含水量。

Working principle: when the pavement cold regenerator moves forward, the rotor rotates upward to mill the raw pavement materials. At the same time, the water is transported from the water truck connected to the pavement cold regenerator through the hose and sprayed in the mixing bin of the pavement cold regenerator. The delivery volume of water is accurately controlled by the microprocessor-controlled pumping system to achieve the required water content.

銑刨轉子將水與銑刨料充分拌和。液體穩定劑，例如熱瀝青(冷再生機自帶泡沫瀝青發泡裝置，可將熱瀝青加熱到160-180°C，與少量水混合發泡)可通過專門設計的噴灑嘴被噴灑到拌和腔；粉狀穩定劑如水泥需按設計添加量事先灑布在路面冷再生機前的路面上，路面冷再生機將粉狀穩定劑與再生料和水一次性拌和。如遇再生層原級配不好的情況，可在再生前將所缺少的部分集料灑布在路面上，通過與舊料拌和來改善原路面材料的級配。

The milling rotor shall fully mix the water with the milling material. Liquid stabilizer, such as hot asphalt (cold recycling machine with foam asphalt foaming device, can heat asphalt to 160-180 degrees C, mixing with a small amount of water) can be sprayed to the mixing chamber through a specially designed spray nozzle. Powdery stabilizer such as cement shall be sprinkled on the pavement in front of the pavement cold regenerator according to the designed addition amount, and the pavement cold regenerator shall mix the powdery stabilizer with recycled material and water at one time. If the original gradation of the recycled layer is not good, the missing part of the aggregate can be sprinkled on the pavement before regeneration, and the gradation of the original pavement materials can be improved by mixing with the old materials.
