冷再生機(jī)租賃的核心價(jià)值，在于以更低成本獲得適配工況的專(zhuān)業(yè)設(shè)備與技術(shù)支持。但要真正實(shí)現(xiàn)“省本增效”，選對(duì)設(shè)備只是第一步，施工配合才是關(guān)鍵。

The core value of leasing cold recycling machines lies in obtaining professional equipment and technical support that are suitable for operating conditions at a lower cost. But to truly achieve "cost saving and efficiency increasing", selecting the right equipment is only the first step, and construction coordination is the key.

冷再生施工不是“單機(jī)作戰(zhàn)”。 冷再生技術(shù)施工是由一系列機(jī)械組合而成的機(jī)組來(lái)完成的，機(jī)組中非常重要的就是再生機(jī)械的選擇。全套機(jī)組通常包括：冷再生機(jī)（核心）、水泥撒布車(chē)（添加膠凝材料）、水罐車(chē)（調(diào)節(jié)含水量）、壓路機(jī)（初壓和終壓）、平地機(jī)（整平）等。一臺(tái)水泥撒布車(chē)甚至可以同時(shí)供應(yīng)2至4臺(tái)冷再生路拌機(jī)施工。

Cold recycling construction is not a 'single machine operation'. The construction of cold recycling technology is completed by a series of mechanical units, and the most important thing in the units is the selection of recycling machinery. The complete set of equipment usually includes: cold regeneration machine (core), cement spreading truck (adding cementitious materials), water tank truck (adjusting water content), roller (initial and final pressure), grader (leveling), etc. A cement spreader can even supply 2 to 4 cold recycling road mixers for construction at the same time.

施工前的準(zhǔn)備工作決定成敗。 施工前應(yīng)確定不均勻材料區(qū)域或路面厚度，明確沒(méi)有足夠厚度或路基強(qiáng)度支撐再生車(chē)組重力的區(qū)域。這些強(qiáng)度不足的區(qū)域建議在再生前糾正，否則冷再生機(jī)有可能穿透路面，造成施工延誤和費(fèi)用增加。對(duì)于技術(shù)工人，要通過(guò)學(xué)習(xí)技術(shù)規(guī)范和操作規(guī)程，提高施工操作水平。

The preparation work before construction determines success or failure. Before construction, the uneven material area or pavement thickness should be determined, and the areas where there is insufficient thickness or roadbed strength to support the gravity of the recycled vehicle group should be identified. It is recommended to correct these areas with insufficient strength before regeneration, otherwise the cold regeneration machine may penetrate the road surface, causing construction delays and increased costs. For technical workers, it is necessary to improve their construction operation level by learning technical specifications and operating procedures.

全深式就地冷再生的工藝優(yōu)勢(shì)。 全深式就地冷再生施工工藝主要采用冷再生設(shè)備對(duì)破損瀝青路面進(jìn)行冷銑刨、破碎、篩選，按比例加入新集料、再生結(jié)合料、水泥、石灰、水等，常溫?cái)嚢韬箐佋O(shè)路面，再經(jīng)突出成型。這一工藝有一整套工序在現(xiàn)場(chǎng)有序完成。不需要租賃使用材料搬運(yùn)運(yùn)輸車(chē)，因?yàn)樵偕牧鲜蔷偷厝〉玫?，可以直接攤鋪，避免了運(yùn)輸過(guò)程中可能出現(xiàn)的離析現(xiàn)象，同時(shí)節(jié)省了大量資金和人力。

The process advantage of fully deep on-site cold regeneration. The full depth on-site cold recycling construction technology mainly uses cold recycling equipment to cold mill, crush, and screen damaged asphalt pavement. New aggregates, recycled binders, cement, lime, water, etc. are added in proportion, and the pavement is laid after mixing at room temperature and then rolled into shape. This process involves a complete set of procedures that are completed in an orderly manner on site. There is no need to rent material handling and transportation vehicles, as recycled materials are obtained on-site and can be directly spread, avoiding possible segregation during transportation and saving a lot of money and manpower.

山區(qū)公路施工的非常提醒。 山區(qū)公路工況復(fù)雜，對(duì)冷再生機(jī)的靈活性和適應(yīng)性要求更高。維特根W 380 CR在貴州G354公路改造項(xiàng)目中的實(shí)踐證明，選對(duì)設(shè)備能巧妙適配山區(qū)復(fù)雜工況。山區(qū)施工要非常注意設(shè)備的爬坡能力、轉(zhuǎn)彎半徑和作業(yè)穩(wěn)定性。

Special Reminder for Highway Construction in Mountainous Areas. The working conditions of mountainous roads are complex, and higher requirements are placed on the flexibility and adaptability of cold recycling machines. The practice of the Weitgen W 380 CR in the Guizhou G354 highway renovation project has proven that selecting the right equipment can cleverly adapt to complex working conditions in mountainous areas. Special attention should be paid to the climbing ability, turning radius, and operational stability of equipment during construction in mountainous areas.
