在道路養護領域，冷再生機如同擁有 “妙手回春” 能力的 “路面醫生”，無需大規模開挖重建，就能讓老舊路面重獲新生。通過租賃冷再生機，施工方能夠以更經濟的方式處理多種路面病害，而其適用范圍之廣，堪稱路面修復的 “全能選手”。

　　In the field of road maintenance, cold recycling machines are like "road doctors" with the ability to "rejuvenate" old roads without the need for large-scale excavation and reconstruction. By leasing a cold recycling machine, the construction party can deal with various road surface diseases in a more economical and environmentally friendly way, and its wide range of applications makes it a "versatile player" in road surface repair.

　　一、瀝青路面的 “深度修復術”

　　1、 Deep repair technique for asphalt pavement

　　冷再生機對瀝青路面的修復堪稱 “教科書級操作”。針對因長期碾壓產生的車轍、龜裂等中等病害，冷再生機可通過銑刨、破碎舊路面，將老化的瀝青混合料與新添加的再生劑、水等均勻拌合，重新攤鋪壓實，形成新的路面結構。這種工藝無需將舊料運輸離場，直接現場再生利用，能節省 30% 以上的材料成本。而對于輕微破損的瀝青路面（如輕度網裂、麻面），冷再生機可采用淺層冷再生工藝，銑刨深度控制在 2-5 厘米，通過添加適量新料與粘結劑，恢復路面平整度與抗滑性能，尤其適合城市主干道、高速公路的預防性養護。

　　The repair of asphalt pavement by cold recycling machine can be called a "textbook level operation". For moderate diseases such as ruts and cracks caused by long-term rolling, the cold recycling machine can mill and crush the old road surface, evenly mix the aged asphalt mixture with newly added rejuvenators, water, etc., and re pave and compact to form a new road structure. This process does not require the transportation of old materials out of the site, and can be directly recycled on site, saving more than 30% of material costs. For slightly damaged asphalt pavement (such as mild mesh cracking and rough surface), the cold recycling machine can use shallow cold recycling technology, with milling depth controlled at 2-5 centimeters. By adding appropriate amounts of new materials and binders, the pavement smoothness and anti-skid performance can be restored, especially suitable for preventive maintenance of urban main roads and highways.

　　二、水泥路面的 “柔性改造法”

　　2、 Flexible Renovation Method for Cement Pavement

　　傳統水泥路面出現斷板、錯臺等病害時，通常需要破除重建，但冷再生機為其提供了更靈活的解決方案。通過冷再生機的強力破碎功能，可將老舊水泥路面破碎成粒徑均勻的顆粒，與瀝青乳液、水等拌合后，作為基層或底基層使用，上方再鋪設新的瀝青面層，形成 “白改黑” 復合路面。這種工藝既能解決水泥路面的反射裂縫問題，又能提升行車舒適性，常用于城市舊城區道路改造、工業園區路面升級等場景。此外，冷再生機處理后的水泥破碎料無需外運，可直接作為路基填料，減少建筑垃圾排放。

　　When traditional cement pavement suffers from defects such as broken boards and staggered platforms, it usually needs to be dismantled and rebuilt, but cold recycling machines provide a more flexible solution. Through the powerful crushing function of the cold recycling machine, the old cement pavement can be broken into particles with uniform particle size. After mixing with asphalt lotion, water, etc., it can be used as the base or subbase. A new asphalt surface layer will be paved above it to form a "white to black" composite pavement. This process can not only solve the problem of reflection cracks on cement pavement, but also improve driving comfort, and is commonly used in scenarios such as road renovation in urban old urban areas and road upgrading in industrial parks. In addition, the cement crushed material processed by the cold recycling machine does not need to be transported outside and can be directly used as roadbed filling, reducing construction waste emissions.

　　三、復合路面的 “分層診療方案”

　　3、 Layered diagnosis and treatment plan for composite pavement

　　對于瀝青與水泥復合結構的路面（如橋面鋪裝層、多層結構路面），冷再生機可實現 “精準分層修復”。例如，當橋面瀝青鋪裝層出現推移、脫層時，冷再生機可精確控制銑刨深度，僅去除破損的瀝青層，保留完好的水泥混凝土基層，再重新鋪筑新的瀝青混合料，避免對橋梁主體結構造成影響。在處理市政道路的 “加鋪層” 病害時，冷再生機可將多層不同材質的舊路面同步破碎拌合，通過調整再生劑配比，使再生料滿足新的強度要求，適用于交通量中等、對路面性能要求較高的次干路與支路。

　　For asphalt and cement composite pavement structures (such as bridge deck pavement layers and multi-layer pavement structures), cold recycling machines can achieve "precise layer by layer repair". For example, when the asphalt pavement layer on the bridge deck is displaced or delaminated, the cold recycling machine can accurately control the milling depth, only remove the damaged asphalt layer, retain the intact cement concrete base, and then re lay a new asphalt mixture to avoid affecting the main structure of the bridge. When dealing with the "pavement layer" disease of municipal roads, the cold recycling machine can synchronously crush and mix multiple layers of old road surfaces of different materials. By adjusting the proportion of recycling agents, the recycled materials can meet the new strength requirements, which is suitable for secondary roads and branches with medium traffic volume and high requirements for road performance.

　　四、特殊場景的 “定制化修復”

　　4、 Customized repair for special scenarios

　　冷再生機租賃的靈活性使其能適應多種特殊路面場景。在廠區、停車場等重載區域，當路面出現嚴重車轍或結構損壞時，冷再生機可采用大厚度銑刨（深度可達 15-30 厘米），將舊料破碎后添加高強度粘結劑，重新壓實形成高承載力的再生基層，滿足重型車輛通行需求。而在旅游景區、步行街等對環境要求高的區域，冷再生機施工噪音低、粉塵少的特點尤為適用，其冷拌工藝無需高溫加熱，避免了傳統熱再生的瀝青煙氣污染，同時可通過添加彩色再生劑，鋪筑彩色再生路面，兼顧功能與景觀效果。

　　The flexibility of leasing cold recycling machines enables them to adapt to various special road scenarios. In heavy-duty areas such as factories and parking lots, when severe ruts or structural damage occur on the road surface, the cold recycling machine can use thick milling (up to 15-30 centimeters deep) to crush the old materials, add high-strength binders, and re compact them to form a high bearing capacity recycled base layer, meeting the needs of heavy vehicle traffic. In areas with high environmental requirements such as tourist attractions and pedestrian streets, the cold recycling machine is particularly suitable for its low construction noise and low dust. Its cold mixing process does not require high temperature heating, avoiding the asphalt smoke pollution caused by traditional hot recycling. At the same time, by adding colored recycling agents, colored recycled road surfaces can be paved, balancing functionality and landscape effects.

　　五、與經濟性的 “雙重優勢”

　　5、 Dual advantages of environmental protection and economy

　　冷再生機租賃的核心價值不僅在于處理路面類型的多樣性，更在于其綠色低碳的工藝特性。與傳統銑刨重鋪相比，冷再生工藝可減少 80% 以上的舊料外運，降低運輸能耗與成本；現場冷拌技術無需燃油加熱，每路面再生可減少約 30 噸碳排放，契合 “雙碳” 目標。此外，租賃模式避免了設備購置的巨額投入，施工方按需租用不同型號的冷再生機（如小型車載式、大型履帶式），既能應對市政小面積修復，也能承接高速公路大規模再生工程，實現資源的利用。

　　The core value of leasing cold recycling machines lies not only in handling the diversity of road surface types, but also in their green and low-carbon process characteristics. Compared with traditional milling and repaving, the cold recycling process can reduce the transportation of old materials by more than 80%, lowering transportation energy consumption and costs; On site cold mixing technology does not require fuel heating, and can reduce carbon emissions by about 30 tons per kilometer of road regeneration, which is in line with the "dual carbon" goal. In addition, the leasing model avoids the huge investment in equipment procurement, and the construction party rents different models of cold recycling machines (such as small vehicle mounted and large tracked) as needed, which can not only cope with small-scale municipal repairs, but also undertake large-scale highway recycling projects, achieving efficient utilization of resources.
