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.

不僅可以減少材料的浪費，以及降低運輸成本。同時它不會影響正常的流量。不破壞道路綠化帶和植被，它是的公路養護施工隊伍。但它的缺點是相關設備是昂貴的，并且該材料均勻組合物的設計差異會造成困難。

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.

為基座上的公路冷再生租賃攪拌設備，以及一個下層，維護二級公路的表面層。這項技術的優點是過程控制，該技術是成熟的，缺點是，為了實現在覆蓋表面的一定厚度所需的技術。

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.

當地熱再生技術適合于預防皮膚再生和保護，并以這種方式的材料，也可以充分利用，運輸成本低，但其更高的設備成本，不能的結構的疾病;熱拌廠適用于再生密集再生，材料成分設計嚴格的方式，也有良好的技術支持，但較大的設備及相關物質轉化成本，公司主營業務之一是冷再生租賃，有需要的朋友歡迎前來咨詢。

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.
