The construction process of cold regenerator has no regional restrictions, and this process can be used for asphalt pavement all over the country. It is estimated that if it is popularized, a prefecture level city should be equipped with 3-5 sets. As a mature model in developed regions in Europe and America, the domestic ownership is so low for many reasons, and 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(zhuǎn)子。機器在舊路面上沿工作面行駛，轉(zhuǎn)子下降到設定深度，高速旋轉(zhuǎn)，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(tǒng)根據(jù)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(nèi)自動噴灑定量的水。

The working device of the cold regenerator is a milling mixing rotor equipped with a large number of special milling cutters. The machine runs along the working face on the old road, the rotor drops to the set depth, rotates at high speed, milling and crushing the raw road materials (including surface course and base course). At the same time, the water spraying system draws water from the accompanying water truck according to the driving speed and milling depth, and automatically sprays a certain amount of water into the cover of the working device.

水的輸送量通過微處理器控制的泵送系統(tǒng)精 確控制。銑刨轉(zhuǎn)子將水與銑刨料充分拌和均勻。液體穩(wěn)定劑，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(nèi)；粉狀穩(wěn)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(wěn)定劑與路面和水一次性破碎并拌和均勻。

The delivery of water is accurately controlled by the microprocessor-controlled pumping system. The milling rotor shall fully mix the water and milling materials evenly. Liquid stabilizer, the cold regenerator can be equipped with emulsified asphalt spraying device, and the emulsified asphalt can be sprayed into the housing of the working device through a specially designed nozzle; Powdery stabilizer, such as cement, can be distributed on the working face of the regenerator according to the designed addition amount. The regenerator will crush and mix the powdery stabilizer with the pavement and water at one time.

就地冷再生技術(shù)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(xiāng)間公路的維修與改造。此技術(shù)在上世紀五十年代開始在歐美等得到應用，目前已是發(fā)達已獲得較為普遍的應用，并常常作為路面維修的選擇方案。近幾年來，就地冷再生技術(shù)在我國受到了業(yè)內(nèi)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(qū)已經(jīng)應用相當普遍，并且取得了良好的社會及經(jīng)濟效果。

In situ cold regeneration technology is not only suitable for the maintenance and reconstruction of high-grade roads, but also for the maintenance and reconstruction of general roads and rural roads. This technology has been applied in Europe, America and other countries since the 1950s. At present, it has been widely used in developed countries, and is often used as an option for pavement maintenance. In recent years, in-situ cold regeneration technology has been widely concerned and recognized by people in the industry in China, and its popularization speed is very fast. For example, it has been widely used in Liaoning, Jilin and Hebei, and has achieved good social and economic results.
