一般来说，长期经受重型交通的路面会出现路基损坏的情况。为了这种损坏，需要对整个路面进行结构性维修。路面冷再生机将铣刨料全部进行重新利用，加之其经济的处理方式，使得采用泡沫沥青进行冷再生施工成为一种开创性方案，达到而经济的作用。

Generally speaking, road surfaces that have been subjected to heavy traffic for a long time may experience roadbed damage. To eliminate this damage, it is necessary to carry out structural repairs on the entire road surface. The pavement cold recycling machine recycles all the milling materials, and its economical treatment method makes cold recycling construction with foam asphalt a pioneering solution, achieving environmental protection and economic effect.

组成：路面冷再生机是沥青路面冷再生施工中的主要设备，一般由动力系统、传动系统、工作装置、喷洒系统和操纵控制系统组成。

Composition: The road surface cold regeneration machine is the main equipment in the construction of asphalt road surface cold regeneration, generally composed of a power system, transmission system, working device, spraying system, and control system.

工作原理：路面冷再生机向前行进时，转子向上旋转铣刨原路面材料，同时，水通过软管从路面冷再生机连接的水车中输送过来，并在路面冷再生机的拌和仓中喷洒。水的输送量通过微处理器控制的泵送系统精确控制，以达到需要的含水量。铣刨转子将水与铣刨料充分拌和。

Working principle: When the road surface cold regeneration machine moves forward, the rotor rotates upwards to mill and plane the raw road surface materials. At the same time, water is transported from the water truck connected to the road surface cold regeneration machine through a hose and sprayed in the mixing bin of the road surface cold regeneration machine. The water delivery rate is precisely controlled by a microprocessor controlled pumping system to achieve the required water content. The milling rotor thoroughly mixes water with the milling material.

液体稳定剂，例如热沥青(冷再生机自带泡沫沥青发泡装置，可将热沥青加热到160-180°C，与少量水混合发泡)可通过专门设计的喷洒嘴被喷洒到拌和腔；粉状稳定剂如水泥需按设计添加量事先洒布在路面冷再生机前的路面上，路面冷再生机将粉状稳定剂与再生料和水一次性拌和。如遇再生层原级配不良的情况，可在再生前将所缺少的部分集料洒布在路面上，通过与旧料拌和来改善原路面材料的级配。

Liquid stabilizers, such as hot asphalt (the cold recycling machine has its own foam asphalt foaming device, which can heat the hot asphalt to 160-180 ° C and mix it with a small amount of water for foaming) can be sprayed to the mixing chamber through specially designed spray nozzles; Powdered stabilizers such as cement need to be sprinkled on the road surface in front of the road surface cold regeneration machine according to the designed dosage. The road surface cold regeneration machine mixes the powdered stabilizers with recycled materials and water in one go. If the original gradation of the recycled layer is poor, the missing part of the aggregate can be sprinkled on the road surface before regeneration, and the gradation of the original road surface material can be improved by mixing with the old material.
