While doing a good job in road maintenance, we should also maintain the road construction machines, which can prolong the service life of the machines. What are the maintenance methods for the cold regenerator?

合理的使用沥青设备，使其潜力限度地发挥，是公路机械化施工企业之所求，而保养和维修是程度发挥机械效益的必要前提。近年来，我单位在公路机械化施工中，按照“使用和保养并重”的原则进行管理，改变了以前施工中只注重机械使用，不注重机械保养，很多易于发现的问题被忽略，结果使有些设备的小问题变成大故障，有些甚提前报废。这不仅大大增加了机械维修成本，而且延误了施工，有的甚造成工程质量问题。针对这跟着城市发展速度的加快，各地都在大规模的拆迁和修理路面，路面修理就要用到路面冷再生机，大家一起来了解一下吧！

Rational use of asphalt equipment to give full play to its potential is the requirement of highway mechanized construction enterprises, and maintenance and repair are the necessary premise to give full play to mechanical benefits. In recent years, our company has managed in accordance with the principle of "paying equal attention to use and maintenance" in highway mechanized construction, which has changed the previous construction that only paid attention to the use of machinery and did not pay attention to the maintenance of machinery, and many easily found problems have been ignored. As a result, some small problems of equipment have become major faults, and some even scrapped in advance. This not only greatly increases the cost of mechanical maintenance, but also delays the construction, and some even cause engineering quality problems. In view of this, with the acceleration of urban development, large-scale demolition and pavement repair are being carried out all over the country. Pavement cold recycling machine is required for pavement repair. Let's have a look!

一般来说，路面长时间经受重型交通，会导致路基损坏。为了这种损坏，需要对整个路面进行结构性修理。路面冷再生机将铣刨料全部进行从头使用，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解决方案，到达而经济的效果。

Generally speaking, the pavement will be damaged by heavy traffic for a long time. In order to eliminate this damage, the whole pavement needs to be structurally repaired. The road cold recycling machine has used all kinds of milling materials from scratch. Combined with its economic processing mode, the cold recycling construction of foamed asphalt has become a pioneering solution to achieve environmental protection and economic effect.

路面冷再生机的组成和作业原理

Composition and working principle of pavement cold regenerator

组成：路面冷再生机是沥青路面冷再生施工中的首要设备，一般由动力体系、传动体系、作业设备、喷洒体系和操作操控体系组成。

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

作业原理：路面冷再生机向前行进时，转子向上旋转铣刨原路面资料，同时，水经过软管从路面冷再生机衔接的水车中输送过来，并在路面冷再生机的搅拌仓中喷洒。水的输送量经过微处理器操控的泵送体系操控，以到达需要的含水量。铣刨转子将水与铣刨料充沛搅拌。液体稳定剂，例如热沥青可经过专门规划的喷洒嘴被喷洒到搅拌腔；粉状稳定剂如水泥需按规划增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搅拌。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，经过与旧料搅拌来改善原路面资料的级配。

Operation principle: when the road surface cold regenerator moves forward, the rotor rotates upward to mill the original road surface data. At the same time, the water is transported from the water truck connected with the road surface cold regenerator through the hose and sprayed in the mixing bin of the road surface cold regenerator. The delivery volume of water is controlled by the pumping system controlled by microprocessor to reach the required water content. The milling rotor will fully mix the water with the milling material. Liquid stabilizers, such as hot asphalt, can be sprayed into the mixing chamber through specially planned spray nozzles; Powdery stabilizer such as cement shall be sprinkled on the pavement in front of the pavement cold regenerator according to the planned increase. 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 data can be improved by mixing with the old material.

路面冷再生机的施工办法在全球范围内已得到遍及认可，它在沥青路面的修理方面受到了路途建设部门和修建公司越来越多的关注。种情况，我们在机械管理上制订并确定了每班保养内容，并督促实施。每月的月底进行沥青设备强制保养2-3天，使很多故障在未出现前就被排除了。

The construction method of pavement cold recycling machine has been widely recognized all over the world. It has attracted more and more attention from road construction departments and construction companies in the repair of asphalt pavement. In this case, we formulated and determined the maintenance contents of each shift in mechanical management, and supervised the implementation. Mandatory maintenance of asphalt equipment is carried out at the end of each month for 2-3 days, so that many faults are eliminated before they appear.
