公路養(yǎng)護(hù)降本關(guān)鍵，冷再生機(jī)租賃憑這3點(diǎn)，省30%成本還環(huán)保

　　The key to cost reduction in highway maintenance lies in the leasing of cold recycling machines, which can save 30% of costs and promote environmental protection

　　隨著我國公路里程持續(xù)增加，大批老舊公路進(jìn)入大修養(yǎng)護(hù)階段，瀝青路面翻漿、龜裂、坑槽、車轍等病害頻發(fā)，若養(yǎng)護(hù)不及時(shí)，將嚴(yán)重影響通行安全與公路使用壽命。據(jù)行業(yè)數(shù)據(jù)顯示，我國每年公路養(yǎng)護(hù)工程量超12萬公里，傳統(tǒng)養(yǎng)護(hù)工藝不僅施工周期長、環(huán)境污染大，且成本居高不下，而冷再生技術(shù)憑借成本低、效率高、環(huán)保性強(qiáng)的優(yōu)勢，已成為公路養(yǎng)護(hù)的主流選擇。對施工單位而言，冷再生機(jī)租賃無需承擔(dān)設(shè)備購置的巨額成本，適配各類公路養(yǎng)護(hù)場景，成為降本增效的核心抓手。今天，結(jié)合河北3.9km公路養(yǎng)護(hù)工程實(shí)例，詳解冷再生機(jī)租賃的核心優(yōu)勢、適配場景及施工工藝要點(diǎn)，為公路施工單位提供實(shí)用參考。

　　With the continuous increase in the mileage of our country's highways, a large number of old roads have entered the stage of major repairs and maintenance. Asphalt pavement diseases such as overturning, cracking, potholes, and ruts occur frequently. If maintenance is not carried out in a timely manner, it will seriously affect traffic safety and the service life of highways. According to industry data, the annual amount of highway maintenance projects in China exceeds 120000 kilometers. Traditional maintenance techniques not only have long construction periods and high environmental pollution, but also have high costs. Cold recycling technology, with its advantages of low cost, high efficiency, and strong environmental protection, has become the mainstream choice for highway maintenance. For construction units, leasing cold recycling machines does not require bearing the huge cost of equipment procurement, and is suitable for various highway maintenance scenarios, becoming the core lever for cost reduction and efficiency improvement. Today, based on the example of the 3.9km highway maintenance project in Hebei, we will explain in detail the core advantages, adaptation scenarios, and construction process points of cold recycling machine leasing, providing practical reference for highway construction units.

　　河北某公路工程，路線全長3.9km，因車流量激增，路面破損嚴(yán)重，出現(xiàn)多種典型病害，經(jīng)鉆芯取樣分析，路面與路基破壞嚴(yán)重，小修無法達(dá)到預(yù)期效果。在方案比選中，施工單位放棄傳統(tǒng)攤鋪、熱再生兩種方案，非常終選擇冷再生技術(shù)，通過冷再生機(jī)租賃模式，完成瀝青面層（6.5cm）與水泥穩(wěn)定砂礫基層（15cm）的銑刨、破碎、拌和等全流程施工，非常終實(shí)現(xiàn)施工周期縮短40%、養(yǎng)護(hù)成本降低35%的良好效果，充分印證了冷再生機(jī)租賃的經(jīng)濟(jì)性與實(shí)用性。

　　A highway project in Hebei Province has a total length of 3.9km. Due to a significant increase in traffic volume, the road surface has suffered severe damage and various typical diseases have appeared. After core sampling analysis, it was found that the road surface and subgrade have been severely damaged, and minor repairs cannot achieve the expected results. In the scheme comparison, the construction unit abandoned the traditional paving and hot recycling schemes and ultimately chose cold recycling technology. Through the leasing mode of cold recycling machines, the entire process of milling, crushing, and mixing of asphalt surface layer (6.5cm) and cement stabilized gravel base layer (15cm) was completed, achieving a good effect of shortening the construction period by 40% and reducing maintenance costs by 35%. This fully confirms the economy and practicality of cold recycling machine leasing.

　　冷再生機(jī)租賃之所以成為公路養(yǎng)護(hù)的優(yōu)選，核心在于其合理適配冷再生技術(shù)的施工需求，同時(shí)解決了施工單位“設(shè)備投入高、閑置率高”的痛點(diǎn)。相較于購置冷再生機(jī)（國產(chǎn)設(shè)備造價(jià)超千萬元，進(jìn)口設(shè)備更高），租賃模式無需一次性投入巨額資金，且可根據(jù)施工工期、工程量靈活調(diào)配設(shè)備，避免設(shè)備閑置造成的資源浪費(fèi)，據(jù)測算，冷再生機(jī)租賃成本僅為購置成本的10%-15%，單公里公路養(yǎng)護(hù)可節(jié)省設(shè)備投入超20萬元。

　　The reason why leasing cold recycling machines has become the preferred choice for highway maintenance lies in its precise adaptation to the construction needs of cold recycling technology, while solving the pain points of high equipment investment and high idle rate for construction units. Compared to purchasing a cold recycling machine (with domestic equipment costing over 10 million yuan and imported equipment costing more), the leasing model does not require a one-time investment of huge funds, and can flexibly allocate equipment according to the construction period and engineering quantity, avoiding resource waste caused by idle equipment. According to estimates, the leasing cost of a cold recycling machine is only 10% -15% of the purchase cost, and single kilometer road maintenance can save equipment investment of over 200000 yuan.

　　結(jié)合工程實(shí)例，冷再生機(jī)租賃的核心優(yōu)勢集中在三點(diǎn)，巧妙契合公路養(yǎng)護(hù)的核心需求。其一，降本效果顯著，冷再生機(jī)可實(shí)現(xiàn)舊路面材料就地再生利用，舊料摻配比例可達(dá)50%以上，避免了新材料采購、運(yùn)輸及舊料清運(yùn)的費(fèi)用，相較于傳統(tǒng)養(yǎng)護(hù)工藝，可降低綜合成本20%-40%，河北該工程憑借冷再生機(jī)租賃，單公里節(jié)省養(yǎng)護(hù)成本近8萬元。其二，施工效率高，冷再生機(jī)可一次性完成舊路面銑刨、破碎、拌和等多道工序，行走速度控制在4-10m/min，搭配租賃的攤鋪機(jī)、突出機(jī)等設(shè)備，單天可完成200-300m公路養(yǎng)護(hù)，較傳統(tǒng)工藝施工效率提升60%，大幅縮短施工周期。

　　Based on engineering examples, the core advantages of leasing cold recycling machines are concentrated in three points, which perfectly meet the core needs of highway maintenance. Firstly, the cost reduction effect is significant. The cold recycling machine can achieve on-site recycling of old road materials, with a mixing ratio of over 50% for old materials, avoiding the cost of purchasing, transporting, and clearing new materials. Compared with traditional maintenance processes, it can reduce comprehensive costs by 20% -40%. With the leasing of the cold recycling machine, this project in Hebei Province has saved nearly 80000 yuan in maintenance costs per kilometer. Secondly, the construction efficiency is high. The cold recycling machine can complete multiple processes such as milling, crushing, and mixing of old road surfaces in one go, with a walking speed controlled at 4-10m/min. Combined with leased pavers, rollers, and other equipment, it can complete 200-300m of road maintenance in a single day, which is 60% more efficient than traditional construction methods and significantly shortens the construction period.

　　其三，環(huán)保合規(guī)，契合綠色施工要求。傳統(tǒng)公路養(yǎng)護(hù)會產(chǎn)生大量路面廢棄物，造成資源浪費(fèi)與環(huán)境污染，而冷再生機(jī)租賃搭配冷再生技術(shù)，可實(shí)現(xiàn)舊路面材料就地再利用，減少廢棄物排放90%以上，同時(shí)避免新材料開采帶來的生態(tài)破壞，符合當(dāng)下公路養(yǎng)護(hù)綠色環(huán)保的發(fā)展趨勢，也能有效規(guī)避環(huán)保處罰風(fēng)險(xiǎn)。

　　Thirdly, environmental compliance and adherence to green construction requirements. Traditional highway maintenance generates a large amount of road waste, resulting in resource waste and environmental pollution. However, the leasing of cold recycling machines combined with cold recycling technology can achieve on-site reuse of old road materials, reduce waste emissions by more than 90%, and avoid ecological damage caused by new material mining. This is in line with the current trend of green and environmental protection in highway maintenance and can effectively avoid environmental penalties.

　　值得注意的是，冷再生機(jī)租賃需結(jié)合施工工藝合理選型，才能非常大化發(fā)揮設(shè)備效能。以河北該工程為例，租賃的就地冷再生機(jī)，搭配3臺灑水車、1臺攤鋪機(jī)、1臺振動突出機(jī)，嚴(yán)格按照施工流程作業(yè)：先完成配合比調(diào)試（選用2:8新舊料配比）、試驗(yàn)路段鋪設(shè)，再進(jìn)行水泥撒布、舊路面破碎與拌和，非常后完成攤鋪、突出、接縫處理及7天養(yǎng)生，全程貼合冷再生施工工藝要求，確保養(yǎng)護(hù)質(zhì)量達(dá)標(biāo)。

　　It is worth noting that the leasing of cold recycling machines requires precise selection based on construction technology in order to maximize equipment efficiency. Taking the Hebei project as an example, the leased on-site cold recycling machine is equipped with 3 sprinkler trucks, 1 paver, and 1 vibrating roller. The construction process is strictly followed: first, the mix proportion is adjusted (using a 2:8 ratio of new and old materials), the test section is laid, then cement is spread, the old road surface is crushed and mixed, and finally the paving, rolling, joint treatment, and 7-day curing are completed. The entire process meets the requirements of cold recycling construction technology to ensure that the maintenance quality meets the standards.

　　當(dāng)前，我國公路養(yǎng)護(hù)行業(yè)正朝著綠色化、出色化、低成本化方向發(fā)展，冷再生機(jī)租賃的市場需求持續(xù)攀升。據(jù)統(tǒng)計(jì)，2025年國內(nèi)冷再生機(jī)租賃市場規(guī)模突破38億元，年復(fù)合增長率達(dá)13.2%，其中公路養(yǎng)護(hù)領(lǐng)域租賃需求占比超75%。對施工單位而言，選擇正規(guī)冷再生機(jī)租賃商家，可獲得設(shè)備調(diào)試、技術(shù)指導(dǎo)等配套服務(wù)，避免因設(shè)備操作不當(dāng)影響施工質(zhì)量，進(jìn)一步降低施工風(fēng)險(xiǎn)。

　　Currently, China's highway maintenance industry is developing towards green, efficient, and low-cost directions, and the market demand for cold recycling machine leasing continues to rise. According to statistics, the scale of the domestic cold recycling machine rental market will exceed 3.8 billion yuan in 2025, with a compound annual growth rate of 13.2%, of which the demand for leasing in the field of highway maintenance accounts for over 75%. For construction units, choosing a legitimate cold recycling machine rental merchant can provide supporting services such as equipment debugging and technical guidance, avoiding the impact of improper equipment operation on construction quality and further reducing construction risks.

　　綜上，冷再生機(jī)租賃是公路養(yǎng)護(hù)降本增效、綠色施工的關(guān)鍵選擇，尤其適配老舊公路大修、低等級公路養(yǎng)護(hù)等場景。結(jié)合工程實(shí)例來看，其不僅能大幅降低設(shè)備投入與養(yǎng)護(hù)成本，還能提升施工效率、減少環(huán)境污染，完全滿足公路養(yǎng)護(hù)的實(shí)際需求。對施工單位而言，合理選用冷再生機(jī)租賃模式，結(jié)合冷再生施工工藝要點(diǎn)，既能確保養(yǎng)護(hù)質(zhì)量達(dá)到預(yù)期，又能實(shí)現(xiàn)經(jīng)濟(jì)效益與環(huán)保效益的雙重提升，在公路養(yǎng)護(hù)市場中搶占優(yōu)勢。

　　In summary, leasing cold recycling machines is a key choice for reducing costs and increasing efficiency in highway maintenance and green construction, especially suitable for scenarios such as major repairs of old highways and maintenance of low-grade highways. Based on engineering examples, it can not only significantly reduce equipment investment and maintenance costs, but also improve construction efficiency, reduce environmental pollution, and fully meet the actual needs of highway maintenance. For construction units, choosing a reasonable leasing model for cold recycling machines, combined with the key points of cold recycling construction technology, can not only ensure that the maintenance quality meets expectations, but also achieve a dual improvement of economic and environmental benefits, and seize the advantage in the highway maintenance market.
