一般來(lái)說(shuō)，長(zhǎng)期經(jīng)受重型交通的路面會(huì)出現(xiàn)路基損壞的情況。為了解決這種損壞，需要對(duì)整個(gè)路面進(jìn)行結(jié)構(gòu)性維修。路面冷再生機(jī)將銑刨料全部進(jìn)行重新利用，加之其經(jīng)濟(jì)的處理方式，使得采用泡沫瀝青進(jìn)行冷再生施工成為一種開(kāi)創(chuàng)性解決方案，達(dá)到而經(jīng)濟(jì)的作用。

Generally speaking, the pavement subject to heavy traffic for a long time will have subgrade damage. In order to solve this damage, the whole pavement needs to be structurally repaired. Pavement cold recycling machine will reuse all the milling materials, and its economic processing mode, making the cold recycling construction of foam asphalt become a pioneering solution to achieve the environmental protection and economic role.

路面冷再生機(jī)的組成和工作原理

Composition and working principle of pavement cold regenerator

組成：路面冷再生機(jī)是瀝青路面冷再生施工中的主要設(shè)備，一般由動(dòng)力系統(tǒng)、傳動(dòng)系統(tǒng)、工作裝置、噴灑系統(tǒng)和操縱控制系統(tǒng)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(jī)向前行進(jìn)時(shí)，轉(zhuǎn)子向上旋轉(zhuǎn)銑刨原路面材料，同時(shí)，水通過(guò)軟管從路面冷再生機(jī)連接的水車中輸送過(guò)來(lái)，并在路面冷再生機(jī)的拌和倉(cāng)中噴灑。水的輸送量通過(guò)微處理器控制的泵送系統(tǒng)控制，以達(dá)到需要的含水量。銑刨轉(zhuǎn)子將水與銑刨料充分拌和。液體穩(wěn)定劑，例如熱瀝青(冷再生機(jī)自帶泡沫瀝青發(fā)泡裝置，可將熱瀝青加熱到160-180°C，與少量水混合發(fā)泡)可通過(guò)專門設(shè)計(jì)的噴灑嘴被噴灑到拌和腔；粉狀穩(wěn)定劑如水泥需按設(shè)計(jì)添加量事先灑布在路面冷再生機(jī)前的路面上，路面冷再生機(jī)將粉狀穩(wěn)定劑與再生料和水一次性拌和。如遇再生層原級(jí)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(guò)與舊料拌和來(lái)改良原路面材料的級(jí)配。

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 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 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. The pavement cold regenerator will mix the powdery stabilizer with recycled materials and water at one time. If the original gradation of the recycled layer is poor, the missing part of the aggregate can be sprinkled on the pavement before regeneration, and the gradation of the original pavement material can be improved by mixing with the old material.
