一、冷再生機的工作過程可以簡單理解為 “破碎 - 混合 - 新生” 三步：

1、 The working process of a cold regeneration machine can be simply understood as three steps: crushing, mixing, and regeneration

破碎舊路：機械力重塑骨料

Broken old roads: mechanical force reshapes aggregates

設備前端的銑刨鼓高速旋轉，刀片如同 “鋼鐵牙齒”，將舊路面按設定深度（通常 10-30 厘米）銑刨成均勻碎塊。這個過程無需高溫加熱，依靠機械力將老化的瀝青混凝土破碎，保留其中仍有強度的骨料，為后續再生奠定基礎。

The milling drum at the front end of the equipment rotates at high speed, and the blades are like "steel teeth", milling the old road surface into uniform fragments at a set depth (usually 10-30 centimeters). This process does not require high temperature heating and relies on mechanical force to crush the aged asphalt concrete, retaining the aggregates that still have strength, laying the foundation for subsequent regeneration.

均勻混合：再生劑激活舊料

Uniform mixing: Regeneration agent activates old materials

破碎后的舊料與再生劑（如乳化瀝青、水泥、水）在設備內部的攪拌倉充分混合。再生劑就像 “激活劑”，重新賦予舊骨料粘結力，同時根據新路面的性能需求，可能添加少量新砂石調整級配。整個攪拌過程由設備自動控制比例，確保再生混合料的強度和耐久性達標。

The crushed old materials are thoroughly mixed with rejuvenators (such as emulsified asphalt, cement, water) in the mixing bin inside the equipment. Recycled agents are like "activators" that reabsorb the bonding strength of old aggregates, while adjusting the gradation by adding a small amount of new sand and gravel according to the performance requirements of the new pavement. The entire mixing process is automatically controlled by the equipment to ensure that the strength and durability of the recycled mixture meet the standards.

攤鋪壓實：新路面快速成型

Laying and compaction: rapid formation of new road surface

攪拌均勻的混合料通過設備尾部的攤鋪裝置，直接鋪設在原路面上，形成平整的基層或面層。隨后，壓路機跟進壓實，讓再生后的路面迅速具備承載能力。從舊路銑刨到新路面成型，整個流程可在同一天內完成，實現 “即修即通” 的高效施工。

The evenly mixed material is directly laid on the original road surface through the paving device at the tail of the equipment, forming a smooth base or surface layer. Subsequently, the road roller followed up with compaction, allowing the regenerated road surface to quickly have bearing capacity. The entire process from milling and planing the old road to shaping the new road surface can be completed in the same day, achieving efficient construction with "instant repair and completion".

二、哪些場景適合選擇冷再生機租賃？

2、 Which scenarios are suitable for choosing cold recycling machine rental?

1. 中小規模翻新項目

1. Small and medium-sized renovation projects

無論是城市支路的裂縫修補，還是鄉鎮公路的車轍處理，冷再生機租賃都能靈活應對。例如，某縣城的商業街路面因長期碾壓出現松散，租賃小型冷再生機（銑刨寬度 1.5 米），僅用 3 天就完成了 5000 平方米的翻新，成本比全挖重建降低 40%，且施工期間周邊商鋪正常營業，實現了效率與影響的平衡。

Whether it is crack repair on urban branches or rutting treatment on township roads, cold recycling machine leasing can flexibly respond. For example, the road surface of a commercial street in a certain county town became loose due to long-term compaction. A small cold recycling machine (milling width of 1.5 meters) was rented to complete the renovation of 5000 square meters in just 3 days, reducing costs by 40% compared to full excavation reconstruction. During the construction period, surrounding shops were operating normally, achieving a balance between efficiency and impact.

2. 臨時應急搶修

2. Temporary emergency repair

暴雨后的道路塌陷、冬季凍融導致的大面積破損，需要快速恢復通行。冷再生機租賃的即時性優勢在此凸顯：設備可迅速進場，無需等待新材料運輸，直接利用舊料再生，24 小時內就能完成應急搶修，最大限度減少交通中斷時間。

Road collapse after rainstorm and large-scale damage caused by freezing and thawing in winter require rapid recovery of traffic. The immediate advantage of renting a cold recycling machine is highlighted here: the equipment can be quickly brought in without waiting for new material transportation, and old materials can be directly recycled. Emergency repairs can be completed within 24 hours, minimizing traffic interruption time.

3. 環保要求高的工程

3. Projects with high environmental protection requirements

在生態保護區、水源地周邊修路，傳統廢料處理方式容易造成污染，而冷再生機租賃通過舊料循環利用，減少了開挖和運輸環節的環境影響。例如，某景區道路翻新時，租賃冷再生機處理舊路面，避免了砂石開采對周邊植被的破壞，再生后的路面與自然景觀更協調，實現了工程與環保的雙贏。

Building roads around ecological protection areas and water sources can easily cause pollution through traditional waste disposal methods, while leasing cold recycling machines reduces the environmental impact of excavation and transportation by recycling old materials. For example, when renovating a road in a certain scenic area, renting a cold recycling machine to treat the old road surface avoids the damage of sand and gravel mining to surrounding vegetation, and the regenerated road surface is more coordinated with the natural landscape, achieving a win-win situation for engineering and environmental protection.

4. 預算有限的基層加固

4. Grassroots reinforcement with limited budget

當道路基層強度不足但面層尚可利用時，冷再生機可將舊基層與部分面層銑刨，加入固化劑（如石灰、粉煤灰）重新攪拌，形成新的半剛性基層。這種 “靶向加固” 的方式，比整體更換基層節省 60% 的材料費用，租賃設備的成本僅為傳統工藝的 1/3，性價比突出。

When the strength of the road base is insufficient but the surface layer is still usable, the cold recycling machine can mill the old base layer and part of the surface layer, add curing agents (such as lime and fly ash) and mix again to form a new semi-rigid base layer. This "targeted reinforcement" method saves 60% of material costs compared to replacing the base layer as a whole, and the cost of renting equipment is only one-third of traditional processes, making it cost-effective.
