在當(dāng)下基礎(chǔ)設(shè)施建設(shè)與道路養(yǎng)護(hù)需求持續(xù)增長(zhǎng)的背景下，冷再生機(jī)租賃業(yè)務(wù)展現(xiàn)出極為廣闊的前景。冷再生機(jī)作為一種、多功能的施工機(jī)械，主要應(yīng)用于瀝青混凝土路面的銑刨，以及添加瀝青、水等材料后對(duì)舊瀝青路面進(jìn)行再生處理，同時(shí)也適用于公路、城鄉(xiāng)道路、機(jī)場(chǎng)、碼頭、停車場(chǎng)等工程的基層、底層穩(wěn)定土現(xiàn)場(chǎng)就地拌和作業(yè)。

　　Against the backdrop of sustained growth in infrastructure construction and road maintenance demand, the leasing business of cold recycling machines shows extremely broad prospects. Cold recycling machine, as an efficient and multifunctional construction machinery, is mainly used for milling and planing asphalt concrete pavement, as well as regenerating old asphalt pavement after adding asphalt, water and other materials. It is also suitable for on-site mixing of stabilized soil at the grassroots and bottom layers of highways, urban and rural roads, airports, docks, parking lots and other projects.

　　從市場(chǎng)需求層面來看，隨著社會(huì)經(jīng)濟(jì)發(fā)展，交通流量日益增大，對(duì)道路質(zhì)量與承載能力提出了更高要求。大量早期修建的道路逐漸出現(xiàn)病害，急需翻新與修復(fù)。傳統(tǒng)道路維修改造方法成本高昂，而冷再生技術(shù)憑借其獨(dú)特優(yōu)勢(shì)脫穎而出。據(jù)相關(guān)資料顯示，與在舊鋪層上加鋪新料的方法相比，就地冷再生可降低成本 20% - 46%，這一顯著的成本優(yōu)勢(shì)使得冷再生機(jī)在道路維修工程中的需求大增。尤其在一些低等級(jí)公路改造項(xiàng)目中，通過冷再生施工提高基層承載力，從根本上實(shí)現(xiàn)道路等級(jí)提升，其應(yīng)用價(jià)值更為凸顯。例如在兵團(tuán)公路養(yǎng)護(hù)項(xiàng)目中，自 2017 年引入就地冷再生設(shè)備開展租賃業(yè)務(wù)以來，已累計(jì)助力 13 個(gè)師市完成大量公路養(yǎng)護(hù)工作，不僅節(jié)約工程成本，還大幅縮短工期，取得了良好的經(jīng)濟(jì)效益與社會(huì)效益。

　　From the perspective of market demand, with the development of social economy and the increasing traffic flow, higher requirements have been put forward for road quality and carrying capacity. A large number of early built roads are gradually showing signs of disease and urgently require renovation and repair. Traditional road maintenance and renovation methods are costly, while cold recycling technology stands out with its unique advantages. According to relevant data, compared with the method of adding new materials on the old pavement layer, on-site cold recycling can reduce costs by 20% to 46%. This significant cost advantage has greatly increased the demand for cold recycling machines in road maintenance projects. Especially in some low-grade highway renovation projects, the application value of using cold recycling construction to improve the bearing capacity of the grassroots and fundamentally achieve road grade improvement is more prominent. For example, in the highway maintenance project of the Xinjiang Production and Construction Corps, since the introduction of on-site cold recycling equipment for leasing business in 2017, a total of 13 cities have been assisted in completing a large amount of highway maintenance work, which not only saves engineering costs but also significantly shortens the construction period, achieving good economic and social benefits.

　　在理念深入人心的當(dāng)下，冷再生機(jī)租賃業(yè)務(wù)也契合了綠色發(fā)展趨勢(shì)。冷再生施工可使所有舊鋪層材料全部就地利用，極大減少了新材料的開采量，同時(shí)避免了舊料運(yùn)輸與堆放問題，從源頭上滿足了環(huán)境保護(hù)需求。以青海省在三江源地區(qū)推廣應(yīng)用冷再生機(jī)為例，通過 “四新” 技術(shù)的實(shí)施，有效解決了農(nóng)村公路養(yǎng)護(hù)中的技術(shù)難題，不僅提高了道路通行能力，還實(shí)現(xiàn)了養(yǎng)護(hù)降本增效，充分體現(xiàn)了冷再生技術(shù)在生態(tài)保護(hù)與工程建設(shè)中的雙重優(yōu)勢(shì)。

　　In the current era where environmental protection concepts are deeply rooted in people's hearts, the leasing business of cold recycling machines also conforms to the trend of green development. Cold recycling construction can make all the old paving materials used in place, greatly reducing the mining output of new materials, avoiding the problem of old material transportation and stacking, and meeting the environmental protection needs from the source. Taking the promotion and application of cold recycling machines in the Sanjiangyuan area of Qinghai Province as an example, the implementation of "four new" technologies has effectively solved the technical problems in rural road maintenance. It not only improves road capacity, but also achieves cost reduction and efficiency improvement in maintenance, fully reflecting the dual advantages of cold recycling technology in ecological protection and engineering construction.

　　技術(shù)的不斷革新也為冷再生機(jī)租賃市場(chǎng)注入新活力。如今的冷再生機(jī)在智能化、自動(dòng)化方面取得顯著進(jìn)展，如部分機(jī)型配備智能控制系統(tǒng)，可根據(jù)行走速度、銑拌深度及銑拌寬度自動(dòng)調(diào)節(jié)噴灑量，實(shí)現(xiàn)精確計(jì)量控制，提高施工質(zhì)量與效率。一些冷再生機(jī)還具備多種轉(zhuǎn)向方式，擁有良好的機(jī)動(dòng)性能，能適應(yīng)復(fù)雜多變的施工環(huán)境。隨著科技持續(xù)進(jìn)步，冷再生機(jī)性能將不斷優(yōu)化，進(jìn)一步拓展其應(yīng)用范圍與市場(chǎng)需求。

　　The continuous innovation of technology has also injected new vitality into the cold recycling machine rental market. The current cold recycling industry has made significant progress in intelligence and automation. For example, some models are equipped with intelligent control systems that can automatically adjust the spraying amount based on walking speed, milling depth, and milling width, achieving precise measurement control and improving construction quality and efficiency. Some cold recycling machines also have multiple steering modes, good maneuverability, and can adapt to complex and changing construction environments. With the continuous advancement of technology, the performance of cold recycling machines will be continuously optimized, further expanding their application scope and market demand.
