冷再生機(jī)租賃：高效筑牢路面基層，解鎖綠色施工新優(yōu)勢(shì)

　　Cold Recycling Machine Rental: Efficiently Building Road Base and Unlocking New Advantages of Green Construction

　　在路面改造工程中，基層的穩(wěn)定性直接決定道路使用壽命，而冷再生機(jī)憑借獨(dú)特的工作原理與核心優(yōu)勢(shì)，既能高效完成路面基層修復(fù)且保持完好無(wú)缺，又能兼顧環(huán)保、節(jié)能等多重需求，成為基建領(lǐng)域的關(guān)鍵設(shè)備。其通過(guò)一體化作業(yè)模式與科學(xué)技術(shù)應(yīng)用，徹底革新了路面基層施工邏輯，彰顯出顯著的工程價(jià)值。

　　In road surface renovation projects, the stability of the base layer directly determines the service life of the road, and the cold recycling machine, with its unique working principle and core advantages, can efficiently complete the repair of the road surface base layer and maintain its integrity, while also meeting multiple needs such as environmental protection and energy conservation, becoming a key equipment in the infrastructure field. Through integrated operation mode and scientific and technological application, it has completely innovated the construction logic of pavement base layer, demonstrating significant engineering value.

　　冷再生機(jī)之所以能高效保障路面基層完好，核心在于其一體化的工作原理與精準(zhǔn)的技術(shù)把控。作為瀝青路面再生機(jī)械的重要類(lèi)型，就地冷再生機(jī)無(wú)需拆分舊路面結(jié)構(gòu)，而是直接利用現(xiàn)有舊鋪層材料，必要時(shí)添加部分新集料與添加劑，在自然溫度下連續(xù)完成銑刨、破碎、添加、拌和、攤鋪及壓實(shí)成型全過(guò)程。針對(duì)不同施工需求，它分為瀝青層就地冷再生與全深式就地冷再生兩種模式：瀝青層就地冷再生多采用多機(jī)式組合，通過(guò)后出料式銑刨機(jī)精準(zhǔn)銑刨50-150mm厚度的瀝青層，經(jīng)破碎篩分后與水、乳化瀝青等材料攪拌，再由攤鋪機(jī)攤鋪、壓路機(jī)壓實(shí)，形成均勻穩(wěn)定的基層；全深式就地冷再生則依托大型路拌機(jī)升級(jí)而來(lái)，銑刨轉(zhuǎn)子深入一定深度的路面材料，同步噴灑泡沫瀝青、水泥稀漿等添加劑，充分拌和后直接攤鋪壓實(shí)，強(qiáng)化基層強(qiáng)度。以維特根系列設(shè)備為例，水泥撒布車(chē)、灑水車(chē)與冷再生機(jī)協(xié)同作業(yè)，通過(guò)推桿連接實(shí)現(xiàn)同步推進(jìn)，銑刨、拌和、輸送、攤鋪一體化完成，避免了工序脫節(jié)導(dǎo)致的基層松散、厚度不均等問(wèn)題，確保基層結(jié)構(gòu)完好、性能穩(wěn)定。

　　The reason why Cold Rejuvenation can efficiently ensure the integrity of the pavement base layer lies in its integrated working principle and precise technical control. As an important type of asphalt pavement recycling machinery, on-site cold recycling machines do not require dismantling the old pavement structure, but directly utilize existing old pavement materials, and add some new aggregates and additives if necessary. They continuously complete the entire process of milling, crushing, adding, mixing, paving, and compacting at natural temperature. For different construction needs, it can be divided into two modes: on-site cold recycling of asphalt layer and full depth on-site cold recycling. The on-site cold recycling of asphalt layer often adopts a multi machine combination, and the asphalt layer with a thickness of 50-150mm is accurately milled by a post discharge milling machine. After crushing and screening, it is mixed with water, emulsified asphalt and other materials, and then spread by a paver and compacted by a roller to form a uniform and stable base layer; Full depth in place cold recycling is upgraded by relying on large road mixers. The rotor is milled into a certain depth of pavement materials, and foam asphalt, cement slurry and other additives are sprayed synchronously. After full mixing, it is directly paved and compacted to strengthen the strength of the base course. Taking the Wittgen series equipment as an example, the cement spreading truck, sprinkler truck, and cold regeneration machine work together through a push rod connection to achieve synchronous propulsion. Milling, mixing, conveying, and paving are integrated to avoid the problems of loose base and uneven thickness caused by process disconnection, ensuring the integrity and stability of the base structure.

　　冷再生機(jī)的核心特點(diǎn)，進(jìn)一步助力其高效完成基層施工并凸顯綜合優(yōu)勢(shì)。舊料全部就地利用是其最突出的環(huán)保優(yōu)勢(shì)，無(wú)需將舊料運(yùn)輸丟棄，既減少了資源浪費(fèi)與環(huán)境污染，又降低了新材料開(kāi)采成本，從源頭踐行綠色施工理念；施工效率大幅提升，一體化作業(yè)模式讓工期縮短一半以上，相比傳統(tǒng)施工省去了舊料清運(yùn)、新料運(yùn)輸攪拌等繁瑣環(huán)節(jié)，且受天氣條件影響小，雨天暫停后晴天即可快速恢復(fù)施工，保障工程進(jìn)度；施工費(fèi)用降低三分之一以上，舊料再利用與工序簡(jiǎn)化減少了材料采購(gòu)、運(yùn)輸及設(shè)備租賃等成本，同時(shí)施工速度快，可強(qiáng)化原有基層、提升道路等級(jí)，延長(zhǎng)道路使用壽命；對(duì)公共交通影響顯著減少，采用半幅施工模式時(shí)，另半幅可照常開(kāi)通，避免了傳統(tǒng)施工導(dǎo)致的長(zhǎng)時(shí)間交通擁堵，兼顧工程推進(jìn)與民生需求。

　　The core characteristics of the cold recycling machine further help it efficiently complete grassroots construction and highlight its comprehensive advantages. The most prominent environmental advantage of using all old materials on site is that there is no need to transport and discard them, which reduces resource waste and environmental pollution, as well as lowers the cost of new material mining, and practices the concept of green construction from the source; The construction efficiency has been greatly improved, and the integrated operation mode has shortened the construction period by more than half. Compared with traditional construction, it eliminates the tedious links of old material removal, new material transportation and mixing, and is less affected by weather conditions. After a rainy day, construction can be quickly resumed on a sunny day, ensuring the progress of the project; The construction cost has been reduced by more than one-third, and the reuse of old materials and simplification of processes have reduced the costs of material procurement, transportation, and equipment leasing. At the same time, the construction speed is fast, which can strengthen the original base, improve road grades, and extend the service life of roads; The impact on public transportation has been significantly reduced. When adopting the half width construction mode, the other half can be opened as usual, avoiding long-term traffic congestion caused by traditional construction and balancing project progress with people's livelihood needs.

　　When using a cold recycling machine for road base construction, the appropriate model should be selected according to the road type and construction requirements. For light traffic roads, on-site cold recycling of asphalt layers can be used, while for heavy traffic roads, it is recommended to use full depth on-site cold recycling to ensure that the base strength meets the standard; Before construction, it is necessary to accurately design the material mix ratio, clarify the utilization rate of old materials, the amount of new aggregate added, and the proportion of additives, and optimize the operation plan based on the technical parameters of high-quality equipment such as Wittgen; During the construction process, it is necessary to ensure the coordination and cooperation of equipment, to ensure that the speed of the spreading truck, sprinkler truck, and cold regeneration machine is consistent, the additives are sprayed evenly, and the mixed material is spread and compacted in a timely manner to avoid affecting the quality of the base layer due to improper process connection; Operators need to be familiar with the multifunctionality of the equipment. Some cold recycling machines can also serve as milling machines and can be flexibly switched according to the construction stage to improve equipment utilization.
