　　瀝青路面養(yǎng)護(hù)中，傳統(tǒng)銑刨、轉(zhuǎn)運(yùn)、廠拌、攤鋪的流程，不僅工期長、能耗高，還會造成大量舊路面材料浪費(fèi)，讓施工單位陷入“成本高、效率低、環(huán)保壓力大”的困境。而冷再生機(jī)的投入使用，有效顛覆了傳統(tǒng)養(yǎng)護(hù)模式，實現(xiàn)“舊路就地再生、廢料循環(huán)利用”，成為公路養(yǎng)護(hù)行業(yè)的綠色升級新選擇。今天，結(jié)合瀝青路面就地冷再生現(xiàn)場施工實景，詳細(xì)拆解冷再生機(jī)施工全流程，解析其核心優(yōu)勢與應(yīng)用價值，用真實施工細(xì)節(jié)展現(xiàn)冷再生機(jī)的實用性，助力行業(yè)從業(yè)者多維度了解冷再生技術(shù)，適配百度收錄需求。

　　In the maintenance of asphalt pavement, the traditional process of milling, transportation, factory mixing, and paving not only has a long construction period and high energy consumption, but also causes a large amount of waste of old pavement materials, putting construction units in a dilemma of "high cost, low efficiency, and high environmental pressure". The use of cold recycling machines has completely overturned the traditional maintenance mode, achieving "on-site regeneration of old roads and recycling of waste materials", becoming a new choice for green upgrading in the highway maintenance industry. Today, based on the on-site construction of asphalt pavement cold recycling, the entire process of cold recycling machine construction is dismantled in detail, and its core advantages and application value are analyzed. The practicality of the cold recycling machine is demonstrated with real construction details, helping industry practitioners to comprehensively understand cold recycling technology and adapt to the needs of Baidu indexing.

　　走進(jìn)瀝青路面就地冷再生施工工地，一臺德通路面就地冷再生機(jī)正出色運(yùn)轉(zhuǎn)，整個施工流程連貫有序，從前期準(zhǔn)備到成型交付，全程無需轉(zhuǎn)運(yùn)舊料、無需場外拌合，真正實現(xiàn)“就地取材、就地施工”。據(jù)行業(yè)實測數(shù)據(jù)顯示，采用冷再生機(jī)施工，較傳統(tǒng)養(yǎng)護(hù)工藝可縮短50%以上工期，減少80%以上碳排放，舊路面材料利用率可達(dá)100%，每萬噸舊料再生可減少砂石開采1.2萬噸，綜合施工成本降低20%-50%，經(jīng)濟(jì)效益與環(huán)保效益顯著。

　　Entering the on-site cold recycling construction site for asphalt pavement, a Detong pavement on-site cold recycling machine is operating efficiently. The entire construction process is coherent and orderly, from early preparation to delivery, without the need to transport old materials or mix outside the site, truly achieving "on-site materials and construction". According to industry test data, using a cold recycling machine for construction can shorten the construction period by more than 50% and reduce carbon emissions by more than 80% compared to traditional maintenance processes. The utilization rate of old road materials can reach 100%, and for every 10000 tons of old materials recycled, 12000 tons of sand and gravel mining can be reduced. The comprehensive construction cost can be reduced by 20% -50%, and the economic and environmental benefits are significant.

　　冷再生機(jī)施工并非簡單的“就地拌合”，而是一套標(biāo)準(zhǔn)化、精細(xì)化的流程，前期準(zhǔn)備工作直接決定施工質(zhì)量。施工前期，首先采用洗爆機(jī)對舊瀝青路面進(jìn)行洗爆處理，將舊路面表層雜質(zhì)、破損部分清理干凈，隨后由山貓設(shè)備進(jìn)行精細(xì)化清掃，確保路面面層無雜物、無浮塵，為后續(xù)冷再生施工筑牢基礎(chǔ)。同時，現(xiàn)場配備水車隨時待命，因就地冷再生施工需用到水資源，水車可根據(jù)施工需求合理補(bǔ)水，保障拌合料濕度達(dá)標(biāo)，避免出現(xiàn)開裂、起砂等質(zhì)量隱患。

　　The construction of cold recycling machines is not simply "on-site mixing", but a standardized and refined process, and the preliminary preparation work directly determines the construction quality. In the early stage of construction, the old asphalt pavement is first washed and blasted using a washing and blasting machine to clean up impurities and damaged parts on the surface of the old pavement. Then, the Bobcat equipment is used for fine cleaning to ensure that the pavement layer is free of debris and floating dust, laying a solid foundation for subsequent cold recycling construction. At the same time, on-site water trucks are on standby at any time. As on-site cold recycling construction requires water resources, water trucks can accurately replenish water according to construction needs, ensuring that the humidity of the mixture meets the standard and avoiding quality hazards such as cracking and sanding.

　　前期準(zhǔn)備就緒后，冷再生機(jī)正式投入作業(yè)，這也是整個施工流程的核心環(huán)節(jié)?，F(xiàn)場可見，舊路面材料被集中堆放于道路中間，之所以選擇居中堆放，核心原因是冷再生機(jī)的攤鋪裝置為居中設(shè)計，居中送料可確保材料均勻分布，保障攤鋪平整度。非常前方的上料行走設(shè)備，將洗爆、清掃后的舊路面材料合理收集，通過傳送帶勻速輸送至現(xiàn)場攪拌列車，實現(xiàn)舊料的出色轉(zhuǎn)運(yùn)與利用。

　　After the preliminary preparations are ready, the cold recycling machine is officially put into operation, which is also the core link of the entire construction process. On site, it can be seen that the old pavement materials are concentrated in the middle of the road. The core reason for choosing to stack them in the center is that the paving device of the cold recycling machine is designed in the center, and the feeding in the center can ensure the uniform distribution of materials and ensure the smoothness of the paving. The front-end feeding and walking equipment accurately collects the washed and cleaned old road materials, and transports them to the on-site mixing train at a constant speed through a conveyor belt, achieving efficient transportation and utilization of the old materials.

　　攪拌列車作為冷再生機(jī)的核心配套設(shè)備，負(fù)責(zé)將舊路面材料與瀝青、水、粗細(xì)骨料等原材料充分拌合、乳化?，F(xiàn)場搭載瀝青罐的列車已準(zhǔn)備就緒，瀝青作為核心粘結(jié)材料，與舊料、骨料、水按科學(xué)配比混合，經(jīng)充分?jǐn)嚢韬?，形成合格的乳化瀝青混凝土，全程在現(xiàn)場完成制備，無需像傳統(tǒng)工藝那樣將材料轉(zhuǎn)運(yùn)至場外拌合站，大幅節(jié)省轉(zhuǎn)運(yùn)成本與時間。

　　As the core supporting equipment for cold regeneration, the mixing train is responsible for fully mixing and emulsifying old pavement materials with raw materials such as asphalt, water, and coarse and fine aggregates. The train carrying asphalt tanks on site is ready. Asphalt serves as the core bonding material and is mixed with old materials, aggregates, and water in a scientific ratio. After thorough mixing, qualified emulsified asphalt concrete is formed, which is fully prepared on site without the need to transport materials to an off-site mixing station like traditional processes, greatly saving transportation costs and time.

　　乳化瀝青混凝土制備完成后，直接送入瀝青攤鋪設(shè)備，按照常規(guī)攤鋪工藝進(jìn)行攤鋪作業(yè)，隨后經(jīng)突出設(shè)備壓實成型，一套完整的就地冷再生施工流程就此完成。整個過程實現(xiàn)了“洗爆—清掃—送料—拌合—攤鋪—突出”相結(jié)合作業(yè)，將瀝青拌合站“搬”到施工現(xiàn)場，有效解決了傳統(tǒng)養(yǎng)護(hù)工藝中舊料浪費(fèi)、轉(zhuǎn)運(yùn)繁瑣、工期漫長的痛點。

　　After the preparation of emulsified asphalt concrete is completed, it is directly sent to the asphalt paving equipment for paving operations according to the conventional paving process. Then, it is compacted and formed by the rolling equipment, and a complete on-site cold recycling construction process is completed. The entire process has achieved an integrated operation of "washing and blasting cleaning feeding mixing paving rolling", moving the asphalt mixing station to the construction site, completely solving the pain points of waste of old materials, cumbersome transportation, and long construction period in traditional maintenance technology.

　　值得注意的是，冷再生機(jī)施工生產(chǎn)的再生路面，質(zhì)量完全符合行業(yè)規(guī)范要求，其60℃動穩(wěn)定度可達(dá)3000次/mm以上，無側(cè)限抗壓強(qiáng)度滿足基層施工標(biāo)準(zhǔn)，不僅能實現(xiàn)舊路翻新，還能提升路面結(jié)構(gòu)強(qiáng)度，延長道路使用壽命。據(jù)調(diào)研，采用冷再生機(jī)施工的路面，使用壽命可達(dá)8-10年，與傳統(tǒng)工藝鋪設(shè)的路面持平，且后期維修頻率大幅降低。

　　It is worth noting that the quality of the recycled pavement produced by the cold recycling machine construction fully meets the industry standard requirements. Its 60 ℃ dynamic stability can reach more than 3000 times/mm, and the unconfined compressive strength meets the basic construction standards. It can not only achieve the renovation of old roads, but also improve the structural strength of the pavement and extend the service life of the road. According to research, the service life of roads constructed using cold recycling machines can reach 8-10 years, which is on par with traditional road paving techniques, and the frequency of later maintenance is significantly reduced.

　　當(dāng)前，綠色低碳養(yǎng)護(hù)成為行業(yè)發(fā)展趨勢，冷再生機(jī)憑借“舊料100%利用、節(jié)能降碳、出色便捷”的核心優(yōu)勢，廣泛應(yīng)用于各級公路、城市道路的養(yǎng)護(hù)改造工程。它不僅破解了傳統(tǒng)養(yǎng)護(hù)的諸多痛點，還踐行了資源循環(huán)利用的理念，為公路養(yǎng)護(hù)行業(yè)高質(zhì)量發(fā)展提供了有力支撐。掌握冷再生機(jī)施工流程與優(yōu)勢，合理投入使用，既能降低施工成本、提升效率，又能實現(xiàn)環(huán)保合規(guī)，助力行業(yè)實現(xiàn)綠色轉(zhuǎn)型升級。

　　Currently, green and low-carbon maintenance has become a trend in the industry. Cold recycling machines, with their core advantages of "100% utilization of old materials, energy conservation and carbon reduction, and high efficiency and convenience," are widely used in maintenance and renovation projects of highways and urban roads at all levels. It not only solves many pain points of traditional maintenance, but also practices the concept of resource recycling, providing strong support for the high-quality development of the highway maintenance industry. Mastering the construction process and advantages of cold recycling machines, and putting them into reasonable use, can not only reduce construction costs and improve efficiency, but also achieve environmental compliance and help the industry achieve green transformation and upgrading.
