行業(yè)資訊
冷再生機作為路面修復(fù)的專用設(shè)備,通過現(xiàn)場對舊路面材料的破碎、拌和與再生利用,重塑路面結(jié)構(gòu)層,在公路養(yǎng)護、市政道路翻新等工程中發(fā)揮著不可替代的作用。其作業(yè)過程無需將舊路面材料搬運離場,既能減少資源浪費,又能縮短施工周期,改變了傳統(tǒng) “開挖 - 清運 - 重建” 的路面修復(fù)模式,成為綠色養(yǎng)護技術(shù)的重要代表。
As a specialized equipment for road surface repair, the cold recycling machine plays an irreplaceable role in highway maintenance, municipal road renovation and other projects by crushing, mixing and recycling old road materials on site, reshaping the road structure layer. The operation process does not require the removal of old pavement materials, which can reduce resource waste and shorten the construction period, changing the traditional "excavation clearing reconstruction" pavement repair mode and becoming an important representative of green maintenance technology.
冷再生機的核心作用在于實現(xiàn)舊路面材料的循環(huán)利用,大幅降低資源消耗與環(huán)境污染。傳統(tǒng)路面修復(fù)需將破損的瀝青或水泥路面破碎后運至填埋場,不僅占用土地資源,還會產(chǎn)生粉塵與運輸尾氣污染。冷再生機則能在現(xiàn)場將舊路面材料(包括瀝青混合料、水泥穩(wěn)定碎石、砂石等)破碎后,與新添加的再生劑(如乳化瀝青、水泥)充分拌和,重新形成符合強度要求的基層或底基層材料,舊料利用率可達(dá) 90% 以上。這種 “就地取材” 的方式,減少了新石料的開采量,也降低了廢棄物運輸量,尤其在石料資源匱乏或運輸成本高的地區(qū),經(jīng)濟效益與環(huán)保效益更為顯著。
The core function of a cold recycling machine is to achieve the recycling of old road materials, significantly reducing resource consumption and environmental pollution. Traditional road surface repair requires crushing damaged asphalt or cement pavement and transporting it to landfills, which not only occupies land resources but also generates dust and transportation exhaust pollution. The cold recycling machine can crush the old pavement materials (including asphalt mixture, cement stabilized crushed stone, sand and gravel, etc.) on site, fully mix them with newly added recycling agents (such as emulsified asphalt, cement), and re form base or sub base materials that meet the strength requirements. The utilization rate of old materials can reach over 90%. This "local material" method reduces the mining output of new stone and the transportation of waste. Especially in areas where stone resources are scarce or transportation costs are high, economic and environmental benefits are more significant.
在施工效率提升方面,冷再生機通過一體化作業(yè)流程縮短路面修復(fù)工期。傳統(tǒng)路面修復(fù)需經(jīng)歷開挖、清運、攤鋪、碾壓等多個環(huán)節(jié),各環(huán)節(jié)需不同設(shè)備配合,工序銜接耗時較長。冷再生機可一次性完成舊路面破碎、材料拌和、攤鋪整型等工序,作業(yè)效率大幅提升,修復(fù)相同長度的公路所需時間明顯縮短。對于交通流量大的路段(如城市主干道),這種高效作業(yè)能減少交通中斷時間,降低因施工造成的交通擁堵影響,通過半幅施工、半幅通行的方式,可實現(xiàn) “邊施工邊通車”,最大限度減少對市民出行的干擾。
In terms of improving construction efficiency, the cold recycling machine shortens the road repair period through an integrated operation process. Traditional road surface repair involves multiple stages such as excavation, transportation, paving, and compaction, which require different equipment to cooperate and take a long time to connect the processes. The cold recycling machine can complete the processes of old road surface crushing, material mixing, paving and shaping in one go, greatly improving operational efficiency and significantly reducing the time required to repair roads of the same length. For road sections with high traffic flow (such as urban main roads), this efficient operation can reduce traffic interruption time and minimize the impact of traffic congestion caused by construction. Through the method of half construction and half traffic, it is possible to achieve "simultaneous construction and traffic opening", minimizing interference with citizens' travel.
冷再生機能夠針對性處理不同類型的路面病害,提升修復(fù)后路面的結(jié)構(gòu)強度。對于瀝青路面的龜裂、車轍、沉陷等病害,冷再生機可根據(jù)病害深度調(diào)整破碎拌和深度,將破損層與部分健康基層一并破碎,加入適量乳化瀝青后重新拌和,形成均勻的再生瀝青基層,其抗壓強度與抗變形能力可達(dá)到新建路面的較高比例。對于水泥路面的斷板、裂縫等問題,冷再生機破碎后添加水泥作為穩(wěn)定劑,拌和后形成的水泥穩(wěn)定再生基層,能有效消除原路面的應(yīng)力集中點,減少修復(fù)后路面的反射裂縫。此外,冷再生機可通過精確控制材料配合比,根據(jù)設(shè)計要求調(diào)整再生層的強度等級,滿足不同交通荷載的需求。
The cold recycling machine can target different types of road surface diseases and improve the structural strength of the repaired road surface. For diseases such as cracking, rutting, and sinking on asphalt pavement, the cold recycling machine can adjust the crushing and mixing depth according to the depth of the disease. The damaged layer and some healthy base layer can be crushed together, and an appropriate amount of emulsified asphalt can be added and re mixed to form a uniform recycled asphalt base layer. Its compressive strength and deformation resistance can reach a high proportion of new pavement. For problems such as broken boards and cracks in cement pavement, cement is added as a stabilizer after being crushed by a cold recycling machine. The cement stabilized recycled base formed after mixing can effectively eliminate stress concentration points on the original pavement and reduce reflection cracks on the repaired pavement. In addition, the cold recycling machine can adjust the strength grade of the recycling layer according to design requirements by precisely controlling the material mix ratio, to meet the needs of different traffic loads.
在成本控制方面,冷再生機作業(yè)能顯著降低路面修復(fù)的綜合費用。直接成本上,由于舊料利用率高,新料采購費用可減少 60%-70%;運輸費用降低(減少舊料外運與新料進場的雙向運輸)。間接成本上,施工周期縮短意味著機械租賃費用與人工費用減少;交通管制成本降低(如臨時圍擋、交通疏導(dǎo)人員的投入減少)。據(jù)測算,采用冷再生技術(shù)的路面修復(fù)工程,總成本通常比傳統(tǒng)工藝低 30%-50%,尤其適合預(yù)算有限的養(yǎng)護工程或低等級公路修復(fù)。
In terms of cost control, the operation of cold recycling machines can significantly reduce the overall cost of road surface repair. In terms of direct costs, due to the high utilization rate of old materials, the procurement cost of new materials can be reduced by 60% -70%; Reduced transportation costs (reducing the two-way transportation of old materials and new materials entering the site). In terms of indirect costs, shortening the construction period means a reduction in machinery rental and labor costs; The cost of traffic control has been reduced (such as temporary fences and reduced input of traffic diversion personnel). According to calculations, the total cost of road surface repair projects using cold recycling technology is usually 30% -50% lower than traditional processes, especially suitable for maintenance projects with limited budgets or the repair of low-grade highways.
冷再生機通過材料循環(huán)利用、效率提升、成本降低等多重作用,推動路面修復(fù)技術(shù)向綠色化、集約化方向發(fā)展。其作業(yè)過程不僅解決了舊路面材料的處理難題,還能保證修復(fù)后路面的使用性能,延長道路使用壽命。隨著養(yǎng)護技術(shù)的不斷升級,冷再生機的功能也在拓展(如智能化控制拌和比例、精準(zhǔn)調(diào)節(jié)壓實度),進一步提升了路面修復(fù)的質(zhì)量與可靠性,成為現(xiàn)代道路養(yǎng)護體系中的關(guān)鍵設(shè)備。
The cold recycling machine promotes the development of road surface repair technology towards green and intensive direction through multiple functions such as material recycling, efficiency improvement, and cost reduction. The homework process not only solves the problem of handling old pavement materials, but also ensures the performance of the repaired pavement and extends the service life of the road. With the continuous upgrading of maintenance technology, the functions of cold recycling machines are also expanding (such as intelligent control of mixing ratio, precise adjustment of compaction degree), further improving the quality and reliability of road surface repair, and becoming a key equipment in the modern road maintenance system.
