一般來說，長期經受重型交通的路面會出現路基損壞的情況。為了消除這種損壞，需要對整個路面進行結構性維修。路面冷再生機將銑刨料全部進行重新利用，加之其經濟的處理方式，使得采用泡沫瀝青進行冷再生施工成為一種開創性解決方案，達到環保而經濟的作用。

Generally speaking, the roadbed will be damaged on the road surface which has suffered heavy traffic for a long time. In order to eliminate this damage, it is necessary to carry out structural maintenance on the whole pavement. 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.

路面冷再生機的組成和工作原理

Composition and working principle of pavement cold recycling machine
              

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, which is generally composed of power system, transmission system, working device, spraying system and 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控制，以達到需要的含水量。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良的情況，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。

Working principle: when the road cold recycling machine moves forward, the rotor rotates upward to mill the raw road materials. At the same time, the water is transported from the water truck connected with the road cold recycling machine through the hose, and sprayed in the mixing bin of the road cold recycling machine. The water delivery is controlled by the pumping system controlled by microprocessor to achieve the required water content. The milling rotor fully mixes 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. ° C. Mixing with a small amount of water (foaming) can be sprayed to the mixing chamber through a specially designed nozzle; The powder stabilizer such as cement should be sprayed on the pavement in front of the cold recycling machine according to the design amount, and the cold recycling machine will mix the powder stabilizer with recycled materials and water at one time. In case of poor grading of the recycled layer, the missing part of the aggregate can be sprayed on the pavement before recycling, and the gradation of the raw pavement materials can be improved by mixing with the old materials.
