在道路建設(shè)與養(yǎng)護(hù)的龐大領(lǐng)域中，施工技術(shù)與設(shè)備的不斷演進(jìn)推動著行業(yè)邁向新高度。冷再生機(jī)作為一種融合了先進(jìn)技術(shù)與創(chuàng)新理念的道路施工設(shè)備，近年來在市場上嶄露頭角，吸引了眾多道路工程從業(yè)者的目光。對于眾多道路施工單位而言，冷再生機(jī)租賃正逐漸成為一種極具吸引力的選擇，它在成本控制、施工效率以及環(huán)保效益等方面展現(xiàn)出諸多優(yōu)勢。?

In the vast field of road construction and maintenance, the continuous evolution of construction technology and equipment is driving the industry to new heights. Cold recycling machine, as a road construction equipment that integrates advanced technology and innovative concepts, has emerged in the market in recent years and attracted the attention of many road engineering practitioners. For many road construction units, leasing cold recycling machines is gradually becoming an attractive choice, demonstrating many advantages in cost control, construction efficiency, and environmental benefits. ?

冷再生機(jī)的工作原理與突出優(yōu)勢?

Working principle and outstanding advantages of cold regeneration machine

冷再生機(jī)主要用于對舊路面材料進(jìn)行再生處理，其工作過程巧妙地結(jié)合了物理破碎與材料混合技術(shù)。設(shè)備前端配備的銑刨裝置，如同一位技藝精湛的工匠，精準(zhǔn)地將舊瀝青路面或水泥路面材料就地打碎，把原本堅(jiān)實(shí)的路面結(jié)構(gòu)分解為大小適宜的顆粒。在這個過程中，冷再生機(jī)嚴(yán)格依照施工要求，通過精確的計(jì)量系統(tǒng)，按比例添加適量的水泥、石灰等結(jié)合料以及水。隨后，強(qiáng)力的攪拌裝置開始運(yùn)作，將這些材料充分?jǐn)嚢杈鶆?，使新加入的結(jié)合料與舊路面材料完美融合，形成具有良好性能的再生混合料。最后，經(jīng)過后續(xù)的攤鋪和壓實(shí)工序，這些再生混合料便被轉(zhuǎn)化為具有所需性能質(zhì)量的新底面層或新基層，為道路的再次使用奠定堅(jiān)實(shí)基礎(chǔ)。?

The cold recycling machine is mainly used for recycling old pavement materials, and its working process cleverly combines physical crushing and material mixing technology. The milling device equipped at the front end of the equipment is like a skilled craftsman, accurately crushing the old asphalt or cement pavement materials on site, and decomposing the originally solid pavement structure into particles of appropriate size. In this process, the cold recycling machine strictly follows the construction requirements and adds appropriate amounts of cement, lime and other binders as well as water in proportion through a precise metering system. Subsequently, the powerful mixing device began to operate, thoroughly mixing these materials evenly, allowing the newly added binder to blend perfectly with the old pavement material, forming a recycled mixture with good performance. Finally, after the subsequent paving and compaction processes, these recycled mixtures are transformed into new bottom layers or base layers with the required performance quality, laying a solid foundation for the reuse of the road. ?

冷再生機(jī)的優(yōu)勢極為顯著，首先體現(xiàn)在成本節(jié)約方面。與傳統(tǒng)的道路施工方法相比，冷再生機(jī)租賃展現(xiàn)出令人矚目的成本優(yōu)勢，通常能為施工項(xiàng)目節(jié)約 20% - 46% 的成本。這一成本的大幅降低，主要源于其對舊料的充分利用，避免了大量新材料的采購與遠(yuǎn)距離運(yùn)輸。以某城市主干道的改造工程為例，傳統(tǒng)施工方案需要采購大量新的砂石料和瀝青，且舊路面拆除后的廢料需要運(yùn)輸至指定地點(diǎn)填埋，成本高昂。而采用冷再生機(jī)租賃服務(wù)，舊路面材料得以全部就地利用，僅需添加少量的水泥、石灰等添加劑，便完成了基層的修復(fù)與重建，不僅減少了材料采購費(fèi)用，還節(jié)省了大量的運(yùn)輸成本，有效降低了整個項(xiàng)目的開支。?

The advantages of cold recycling machines are extremely significant, first reflected in cost savings. Compared with traditional road construction methods, leasing cold recycling machines has shown remarkable cost advantages, typically saving construction projects 20% to 46% of costs. The significant reduction in this cost is mainly due to its full utilization of old materials, avoiding the procurement of a large amount of new materials and long-distance transportation. Taking the renovation project of a main road in a certain city as an example, the traditional construction plan requires the purchase of a large amount of new sand and asphalt materials, and the waste materials after the demolition of the old road surface need to be transported to designated locations for landfill, which is costly. By adopting the leasing service of cold recycling machines, all the old pavement materials can be utilized on site, and only a small amount of additives such as cement and lime need to be added to complete the repair and reconstruction of the base layer. This not only reduces material procurement costs, but also saves a lot of transportation costs, effectively reducing the overall project expenses. ?

冷再生機(jī)施工工期短的特點(diǎn)也為其贏得了眾多施工單位的青睞。傳統(tǒng)道路施工方法需要將舊路面材料全部挖除并運(yùn)走，然后再重新采購、運(yùn)輸和鋪設(shè)新的材料，這一系列工序繁瑣且耗時。而冷再生機(jī)可以直接在施工現(xiàn)場對舊路面進(jìn)行處理，減少了中間諸多環(huán)節(jié)，極大地提高了施工效率。?例如，在一條長度為 10 公里的縣道養(yǎng)護(hù)工程中，若采用傳統(tǒng)施工方式，包括舊路面拆除、廢料運(yùn)輸?shù)拳h(huán)節(jié)，預(yù)計(jì)工期需要 3 個月左右。而使用冷再生機(jī)租賃服務(wù)，施工單位僅用了 1 個半月就順利完成了全部施工任務(wù)，大大縮短了道路封閉時間，為當(dāng)?shù)鼐用窈徒煌◣砹藰O大便利。

The short construction period of the cold recycling machine has also won the favor of many construction units. The traditional road construction method requires the complete excavation and transportation of old pavement materials, followed by the procurement, transportation, and laying of new materials, which is a tedious and time-consuming process. The cold recycling machine can directly treat the old road surface on the construction site, reducing many intermediate links and greatly improving construction efficiency. For example, in a 10 kilometer county road maintenance project, if traditional construction methods are used, including old road surface demolition, waste transportation, etc., the estimated construction period is about 3 months. By using the cold recycling machine rental service, the construction unit successfully completed all construction tasks in just one and a half months, greatly reducing the road closure time and bringing great convenience to local residents and transportation.
