公路養(yǎng)護中冷再生機租賃如何去做？
來源：http://m.hlbeyb.com/ 日期：2021-06-09 發(fā)布人：
冷再生是一種與熱再生相對應的瀝青混合料再生施工方法。冷再生法是利用大功率路面銑刨機在原路面上對路面混合料進行碾磨、挖除、破碎，同時加入穩(wěn)定劑、水泥、水（或乳化瀝青）和骨料進行現(xiàn)場拌合，用路面攪拌機現(xiàn)場拌合，碾壓成型。冷再生施工主要用于低等級路面的修復。
Cold recycling is a kind of asphalt mixture recycling construction method corresponding to hot recycling. The cold recycling method is to use the high-power pavement milling machine to grind, excavate and crush the pavement mixture on the original pavement. At the same time, the stabilizer, cement, water (or emulsified asphalt) and aggregate are added for on-site mixing. The pavement mixer is used for on-site mixing and rolling forming. Cold recycling construction is mainly used for the repair of low-grade pavement.
在對道路進行養(yǎng)護工作時，我們需要對原先的道路進行清查，以確保在冷再生機租賃之后進行道路養(yǎng)護工作中可以順利進行。
In the road maintenance work, we need to check the original road to ensure that the road maintenance work can be carried out smoothly after the rental of cold recycling machine.
冷再生機在公路養(yǎng)護中的應用主要有：
The application of cold recycling machine in highway maintenance mainly includes:
一、舊路清查
1、 Old road inventory
冷再生技術(shù)適用于大部分瀝青混凝土舊路大修與改建工程。先需要對舊路進行詳細的調(diào)查，主要包括以下內(nèi)容：
Cold recycling technology is suitable for most old asphalt concrete road repair and reconstruction projects. First, we need to conduct a detailed investigation on the old road, mainly including the following contents:
1、對舊路結(jié)構(gòu)和歷年修補改造情況進行調(diào)查，了解路面病害情況，包括變形、裂縫、邊緣破壞等。
1. To investigate the old road structure and the repair and reconstruction over the years, to understand the pavement diseases, including deformation, cracks, edge damage, etc.
2、為了分析舊路的破壞和承載能力，有必要對舊路基層進行冷再生利用。
2. In order to analyze the damage and bearing capacity of old road, it is necessary to carry out cold recycling of old road base.
3、對舊路結(jié)構(gòu)進行了鉆芯試驗，以確定舊路結(jié)構(gòu)的厚度和各材料層的技術(shù)特性。
3. In order to determine the thickness of the old road structure and the technical characteristics of each material layer, core drilling test was carried out on the old road structure.
二、材料骨料組成
2、 Material aggregate composition
冷循環(huán)涂層的性能與混合料的級配有著顯著而密切的關(guān)系，如果舊骨料中總粒徑大于等于4.75mm的骨料含量過低，則加入新的分級骨料；如果舊材料中總含量超過4.75mm，則會導致細材料（尤其是小于0.6mm的骨料）對空腔的填充不足。
The performance of the cold cycle coating is significantly and closely related to the gradation of the mixture. If the content of the aggregate with the total particle size of 4.75mm or more in the old aggregate is too low, the new graded aggregate will be added; If the total content of the old material exceeds 4.75mm, it will lead to the insufficient filling of the cavity by the fine material (especially the aggregate less than 0.6mm).
由于混合料的強度較低，因此有必要在冷凍再生混合料中添加一種稍有級配的細骨料，以形成分選良好、密實的骨架結(jié)構(gòu)，提高混合料的強度。但這樣無疑會增加冷再生結(jié)構(gòu)層的成本，需要在與新結(jié)構(gòu)層進行經(jīng)濟比較后實施。
Due to the low strength of the mixture, it is necessary to add a slightly graded fine aggregate to the frozen recycled mixture to form a well sorted and dense skeleton structure and improve the strength of the mixture. But this will undoubtedly increase the cost of the cold regeneration structure layer, which needs to be implemented after the economic comparison with the new structure layer.
冷再生技術(shù)可以充分利用舊路資源，對舊路面層及基層進行再生利用形成新的路面基層。操作簡潔，經(jīng)濟效益顯著。
The cold recycling technology can make full use of the old road resources, regenerate the old pavement layer and base, and form a new pavement base. The operation is simple and the economic benefit is remarkable.
