冷再生机主要适用于以下类型的路面：

　　The cold recycling machine is mainly suitable for the following types of road surfaces:

　　1. 沥青面层材料：冷再生技术可以用于重复使用原有的沥青面层材料，作为路面的基层或底基层，也可作低等级公路面层。

　　1. Asphalt surface layer material: Cold recycling technology can be used to reuse the original asphalt surface layer material as the base or sub base of the road surface, and can also be used as the surface layer of low-grade highways.

　　2. 无机结合料稳定的基层材料：冷再生技术不仅限于沥青面层材料，也可以用于无机结合料稳定的基层材料。

　　2. Inorganic binder stabilized base material: Cold recycling technology is not limited to asphalt surface materials, but can also be used for inorganic binder stabilized base materials.

　　冷再生机在实际应用中，可以实现就地再生，提高施工效率。例如，徐工XLZ3805R沥青面层冷再生机就是针对沥青面层的冷再生作业。此外，冷再生技术已经在一些高速公路的改扩建和维修工程中得到应用，如江苏省的沪宁高速改扩建工程和江西昌九高速维修工程。

　　In practical applications, cold recycling machines can achieve on-site regeneration and improve construction efficiency. For example, the XCMG XLZ3805R asphalt surface cold recycling machine is designed for cold recycling operations of asphalt surfaces. In addition, cold recycling technology has been applied in the renovation, expansion, and maintenance projects of some highways, such as the Shanghai Nanjing Expressway renovation and expansion project in Jiangsu Province and the Changjiu Expressway maintenance project in Jiangxi Province.

　　综上所述，冷再生机在沥青路面的养护维修、基层处理以及低等级公路建设等方面具有广泛的应用前景。

　　In summary, cold recycling machines have broad application prospects in the maintenance and repair of asphalt pavements, base treatment, and construction of low-grade highways.

　　、哪些路面类型，冷再生机无法发挥作用?

　　Which types of road surfaces do cold recycling machines fail to function?

　　冷再生机在不同路面层次和类型中的适用性有所不同，以下是冷再生机最不适合的路面类型：

　　The applicability of cold recycling machines varies in different road levels and types, and the following are the road types that are least suitable for cold recycling machines:

　　1. 路面表面层：厂拌冷再生技术一般不适用于路面的表面层。这是因为表面层需要承受较大的压力和摩擦力，要求材料具有较高的强度、耐磨性和抗滑性。而厂拌冷再生技术所生产的混合料在这些高性能方面存在不足，且水稳定性相对较差，易受水分侵蚀。

　　1. Surface layer of pavement: Factory mixed cold recycling technology is generally not suitable for the surface layer of pavement. This is because the surface layer needs to withstand significant pressure and friction, requiring the material to have high strength, wear resistance, and skid resistance. However, the mixture produced by the factory mixed cold recycling technology has shortcomings in these high-performance aspects, and its water stability is relatively poor, making it susceptible to moisture erosion.

　　2. 特殊类型的灰土材料：冷再生路拌机在处理某些特殊类型的灰土材料时可能存在困难，需要针对具体材料类型进行设备调整或优化。

　　2. Special types of lime soil materials: Cold recycling road mixers may encounter difficulties in processing certain special types of lime soil materials, and equipment adjustments or optimizations need to be made for specific material types.

　　综上所述，冷再生机最不适合用于路面表面层以及某些特殊类型的灰土材料。在选择冷再生技术时，应根据路面层次和材料特性进行合理选择，以确保路面的整体使用效果和安全性。

　　In summary, cold recycling machines are least suitable for use in road surface layers and certain special types of gray soil materials. When choosing cold recycling technology, reasonable selection should be made based on the pavement layer and material characteristics to ensure the overall effectiveness and safety of the pavement.
