An important part of highway maintenance is the reconstruction of old roads. The regeneration mode of old roads can be divided into two types, namely cold and hot recycling, including the following four types: CIR, cold plant mixing regeneration, geothermal regeneration and plant mixing hot regeneration. Among them, the reorganization of the surface structure of the base layer is not expected to occur, and the in-situ cold regeneration technology is applicable, which can realize the local transformation.

不仅可以减少材料的浪费，以及降低运输成本。同时它不会影响正常的流量。不破坏道路绿化带和植被，它是的公路养护施工队伍。但它的缺点是相关设备是昂贵的，并且该材料均匀组合物的设计差异会造成困难。

It can not only reduce the waste of materials, but also reduce the transportation cost. At the same time, it will not affect the normal flow. It is the preferred highway maintenance construction team without damaging the road green belt and vegetation. However, its disadvantage is that the related equipment is expensive, and the design difference of the uniform composition of the material will cause difficulties.

为基座上的公路冷再生租赁搅拌设备，以及一个下层，维护二级公路的表面层。这项技术的优点是过程控制，该技术是成熟的，缺点是，为了实现在覆盖表面的一定厚度所需的技术。

Lease mixing equipment for road cold regeneration on the base and a lower layer to maintain the surface layer of secondary road. The advantage of this technology is process control, which is mature, and the disadvantage is the technology required to achieve a certain thickness on the covered surface.

当地热再生技术适合于预防皮肤再生和保护，并以这种方式的材料，也可以充分利用，运输成本低，但其更高的设备成本，不能的结构的疾病;热拌厂适用于再生密集再生，材料成分设计严格的方式，也有良好的技术支持，但较大的设备及相关物质转化成本，公司主营业务之一是冷再生租赁，有需要的朋友欢迎前来咨询。

When geothermal regeneration technology is suitable for preventing skin regeneration and protection, and materials in this way can also be fully utilized, with low transportation cost, but its higher equipment cost and incurable structural diseases; The hot mix plant is suitable for intensive regeneration, strict material composition design and good technical support, but it has a large conversion cost of equipment and related substances. One of the company's main businesses is cold regeneration leasing. Friends in need are welcome to consult.
