路面冷再生工程實施中的常見問題及處置對策

再生技術應用現狀
Application status of regeneration technology
瀝青路面冷再生技術是目前養護工程的一項較廣泛的應用性技術，它雖然在我國的應用時間不是很長（二十年左右），但基于該項技術的自身特點及符合我國的戰略要求，近些年來，在我國的公路路面養護大、中修工程中達到了大量的使用。
Asphalt pavement cold recycling technology is a widely used technology in maintenance engineering at present. Although it has not been applied for a long time in China (about 20 years), based on its own characteristics and in line with the national strategic requirements of energy conservation and environmental protection, it has been widely used in large and medium-sized highway pavement maintenance projects in China in recent years.
從目前的工程應用程序來看，總體反映良好。本次我省的兩個地方性規范的出臺，對于冷再生技術的使用將產生良好的促進作用，也有利于進一步提升冷再生的工程質量。
From the current national engineering applications, the overall response is good. The introduction of the two local specifications in our province will not only promote the use of cold regeneration technology, but also further improve the engineering quality of cold regeneration.
由于冷再生工程應用的目的之一是基于舊路面材料的循環利用，且材料的利用率高（利用率在百分之90以上），故在具體的項目實施中受影響的因素較多（主要是原路面的結構及用料情況）?，F徐州恒馳工程機械就路面冷再生機工程實施中的常見問題及處置對策提出一些建議，供大家在實際應用中參考。
As one of the purposes of the application of cold recycling engineering is based on the recycling of old pavement materials, and the utilization rate of materials is high (the utilization rate is more than 90%), there are many factors affected in the implementation of specific projects (mainly the structure and material consumption of the original pavement). At present, Xuzhou hengchi construction machinery puts forward some suggestions on the common problems and Disposal Countermeasures in the implementation of pavement cold recycling machine project for your reference in practical application.
水泥就地冷再生
In situ cold recycling of cement
1、設計方面的建議：
1. Design suggestions:
1）、冷再生層的設計厚度：應綜合考慮舊路面的結構層情況確定水泥就地冷再生的設計厚度，避免產生再生層施工后存在超薄夾層的現象。
1) Design thickness of cold recycling layer: the design thickness of cement in-situ cold recycling should be determined by comprehensively considering the structural layer of the old pavement, so as to avoid the phenomenon of ultra-thin interlayer after the construction of recycling layer.
2）、舊路面瀝青層厚度占再生層厚度的比例：在重交通的情況下，考慮再生層的強度要求等因素，建議舊瀝青層厚度比例不應大于百分之30。如舊路面瀝青層厚度較大，應設計先銑刨舊瀝青層（部分或全部），再進行水泥冷再生施工。銑刨的瀝青材料可作廠拌冷（熱）再生進行利用。
2) The proportion of the thickness of the old asphalt layer in the thickness of the recycled layer: in the case of heavy traffic, considering the strength requirements of the recycled layer and other factors, it is recommended that the thickness proportion of the old asphalt layer should not be greater than 30%. If the thickness of the asphalt layer of the old pavement is large, the old asphalt layer (part or all) shall be milled first, and then the cement cold recycling construction shall be carried out. Recycled materials for cold milling.
2、施工方面的問題：
2. Construction problems:
1）、銑刨拌和的均勻性問題：應以再生混合料拌合均勻及不產生離析為目標，控制調整再生機的工作行駛速度和轉子速度（破碎梁開度）等。
1) Uniformity of milling and mixing: Aiming at uniform mixing and no segregation of recycled mixture, control and adjust the working driving speed and rotor speed (opening of crushing beam) of the regenerator.
2）、影響再生層的強度的主要因素：水泥用量及撒布均勻性，拌合用水量的控制，再生層的壓實及封閉養生等。
2) Main factors affecting the strength of the recycled layer: cement dosage and distribution uniformity, control of mixing water consumption, compaction and sealing curing of the recycled layer, etc.
3）、再生層可能產生縱向裂縫問題：再生機縱向搭接處的用水量控制，每作業段長度選擇的合理性等。
3) Longitudinal cracks may occur in the regeneration layer: water consumption control at the longitudinal lap joint of the regeneration machine, rationality of length selection of each operation section, etc.
