行業(yè)資訊
冷再生機(jī)主要適用于以下類型的路面:
The cold recycling machine is mainly suitable for the following types of road surfaces:
1. 瀝青面層材料:冷再生技術(shù)可以用于重復(fù)使用原有的瀝青面層材料,作為路面的基層或底基層,也可作低等級公路面層。
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. 無機(jī)結(jié)合料穩(wěn)定的基層材料:冷再生技術(shù)不僅限于瀝青面層材料,也可以用于無機(jī)結(jié)合料穩(wěn)定的基層材料。
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.
冷再生機(jī)在實(shí)際應(yīng)用中,可以實(shí)現(xiàn)就地再生,提高施工效率。例如,徐工XLZ3805R瀝青面層冷再生機(jī)就是針對瀝青面層的冷再生作業(yè)。此外,冷再生技術(shù)已經(jīng)在一些高速公路的改擴(kuò)建和維修工程中得到應(yīng)用,如江蘇省的滬寧高速改擴(kuò)建工程和江西昌九高速維修工程。
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.
綜上所述,冷再生機(jī)在瀝青路面的養(yǎng)護(hù)維修、基層處理以及低等級公路建設(shè)等方面具有廣泛的應(yīng)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.
、哪些路面類型,冷再生機(jī)無法發(fā)揮作用?
Which types of road surfaces do cold recycling machines fail to function?
冷再生機(jī)在不同路面層次和類型中的適用性有所不同,以下是冷再生機(jī)最不適合的路面類型:
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. 路面表面層:廠拌冷再生技術(shù)一般不適用于路面的表面層。這是因?yàn)楸砻鎸有枰惺茌^大的壓力和摩擦力,要求材料具有較高的強(qiáng)度、耐磨性和抗滑性。而廠拌冷再生技術(shù)所生產(chǎn)的混合料在這些高性能方面存在不足,且水穩(wěn)定性相對較差,易受水分侵蝕。
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. 特殊類型的灰土材料:冷再生路拌機(jī)在處理某些特殊類型的灰土材料時(shí)可能存在困難,需要針對具體材料類型進(jìn)行設(shè)備調(diào)整或優(yōu)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.
綜上所述,冷再生機(jī)最不適合用于路面表面層以及某些特殊類型的灰土材料。在選擇冷再生技術(shù)時(shí),應(yīng)根據(jù)路面層次和材料特性進(jìn)行合理選擇,以確保路面的整體使用效果和安全性。
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.
