冷再生機租賃：舊路變新路的“黑科技”，省百萬成本還減廢料

　　Leasing of cold recycling machines: the "black technology" of transforming old roads into new ones, saving millions of costs and reducing waste

　　在道路養(yǎng)護與改造中，舊水泥路面的處理曾是一大難題——傳統(tǒng)方式需將破損路面全部拆除、清運，不僅產(chǎn)生大量建筑垃圾，還得采購新集料，成本動輒上百萬，工期也冗長。而冷再生機憑借一套高效的就地冷再生水穩(wěn)下基層工藝，把“拆舊建新”變成“舊料重生”，既讓老路變回平整堅固的新路，又省下巨額成本、減少廢料污染，堪稱基建領域的“綠色黑科技”。

　　In road maintenance and renovation, the treatment of old cement pavement was once a major challenge - traditional methods required the complete demolition and removal of damaged pavement, which not only generated a large amount of construction waste, but also required the purchase of new aggregates, with costs often exceeding millions and construction periods being lengthy. The cold regeneration machine, relying on an efficient on-site cold regeneration water stabilizing grassroots process, transforms "demolishing old and building new" into "regenerating old materials". It not only turns old roads back into flat and sturdy new roads, but also saves huge costs and reduces waste pollution, making it a "green black technology" in the field of infrastructure.

　　冷再生機的核心魔力，藏在一套環(huán)環(huán)相扣的就地施工流程里，每一步都圍繞“舊料全利用、強度有保障”展開。改造的第一步，是對舊水泥路面進行碎石化處理——冷再生相關設備會將破損的水泥板破碎成大小均勻的集料，這些原本要被當作廢料運走的舊料，此刻成了再生基層的“主角”。碎石化完成后，進入深度破碎及碾壓環(huán)節(jié)，通過設備進一步細化集料顆粒，同時用壓路機初步壓實，讓集料形成穩(wěn)定的基礎骨架，避免后續(xù)施工中出現(xiàn)沉降。

　　The core magic of the cold recycling machine is hidden in a set of interlocking on-site construction processes, with each step revolving around "fully utilizing old materials and ensuring strength". The first step in the renovation is to crush the old cement pavement - cold recycling equipment will crush the damaged cement boards into uniformly sized aggregates. These old materials, which were originally intended to be transported as waste, have now become the "protagonists" of the recycled base layer. After the crushing process is completed, it enters the deep crushing and rolling stage, where the aggregate particles are further refined by equipment. At the same time, a roller is used for initial compaction to form a stable foundation skeleton of the aggregate, avoiding settlement during subsequent construction.

　　緊接著是二度破碎與調級配，這一步是為了讓集料級配更符合水穩(wěn)基層的強度要求——設備會根據(jù)設計標準，調整不同粒徑集料的比例，確保再生料能緊密咬合，提升基層的承載能力。隨后，水泥智能定量灑布車登場，這是冷再生技術精準控料的關鍵：通過智能系統(tǒng)實時調節(jié)撒布量，即便設備行進速度變化，也能保證水泥均勻覆蓋在破碎后的路面上，既不會因水泥過多導致基層開裂，也不會因過少影響粘結強度，為再生料的穩(wěn)定提供核心“粘合劑”。

　　The next step is secondary crushing and grading, which is to make the aggregate grading more in line with the strength requirements of the water stable base layer. The equipment will adjust the proportion of different particle sizes of aggregates according to the design standards to ensure that the recycled materials can be tightly interlocked and improve the bearing capacity of the base layer. Subsequently, the intelligent quantitative spraying truck for cement was introduced, which is the key to precise material control in cold recycling technology: by adjusting the spraying amount in real time through the intelligent system, even if the equipment's travel speed changes, it can ensure that the cement is evenly covered on the broken road surface. It will not cause cracking of the base layer due to excessive cement, nor will it affect the bonding strength due to insufficient cement, providing the core "adhesive" for the stability of recycled materials.

　　當水泥撒布完成，就地再生機械便成為流程的核心。它會將粉碎的舊水泥板集料與水泥、適量水分充分攪拌，讓每一粒集料都裹覆水泥漿，形成均勻的再生混合料。攪拌完成后，先用壓路機靜壓1-2遍初步固定形態(tài)，再用平地機根據(jù)設計標高和縱橫坡度仔細整平，確保路面平整度達標。之后換上26噸振動壓路機加壓4-5遍，讓混合料致密成型，最后用膠輪壓路機碾壓1-2遍，進一步提升基層的平整度與密實度，一套“舊料變新基層”的操作就此完成。

　　When the cement spreading is completed, on-site recycling machinery becomes the core of the process. It will thoroughly mix the crushed old cement board aggregate with cement and an appropriate amount of water, so that each aggregate is coated with cement slurry, forming a uniform recycled mixture. After mixing is completed, first use a roller to statically press 1-2 times to preliminarily fix the shape, and then use a grader to carefully level the road surface according to the design elevation and longitudinal and transverse slopes to ensure that the road surface smoothness meets the standard. Afterwards, a 26 ton vibratory roller was used to pressurize the mixture 4-5 times, allowing it to compact and form. Finally, a rubber roller was used to roll the mixture 1-2 times, further improving the flatness and compactness of the base layer. This completed the operation of "old material to new base layer".

　　流程的最后是養(yǎng)生環(huán)節(jié)，這一步直接關系到基層的最終強度。經(jīng)質檢合格后，工作人員會對水泥穩(wěn)定碎石路段噴霧灑水，保持基層濕潤，隨后立即覆蓋塑料薄膜鎖水。養(yǎng)護期內需要封閉道路，避免外力擾動，7天的養(yǎng)護時間能讓水泥充分水化反應，讓再生基層達到設計強度，為后續(xù)路面面層施工筑牢基礎。

　　The final step of the process is the health preservation stage, which directly affects the final strength of the grassroots level. After passing the quality inspection, the staff will spray water on the cement stabilized macadam section to keep the base layer wet, and then immediately cover the plastic film to lock the water. During the maintenance period, the road needs to be closed to avoid external disturbances. A 7-day maintenance period can allow the cement to fully hydrate and react, enabling the recycled base to reach the design strength and laying a solid foundation for subsequent pavement surface construction.

　　Practical suggestions for road construction

　　采用冷再生機進行舊路改造時，需提前勘察舊路面破損程度，根據(jù)集料情況調整碎石化與調級配參數(shù)，確保再生料級配達標；水泥撒布前需校準智能灑布車的計量系統(tǒng)，避免因誤差影響基層質量；整平環(huán)節(jié)要嚴格把控標高與坡度，可通過掛線測量實時調整，確保路面平整度符合規(guī)范；養(yǎng)護期務必做好道路封閉管理，禁止車輛行人進入，同時定期檢查薄膜覆蓋情況，防止水分過快蒸發(fā)影響?zhàn)B生效果。

　　When using a cold recycling machine for old road reconstruction, it is necessary to investigate the degree of damage to the old road surface in advance, adjust the crushing and grading parameters according to the aggregate situation, and ensure that the grading of the recycled materials meets the standard; Before spreading cement, it is necessary to calibrate the measuring system of the intelligent sprinkler truck to avoid affecting the quality of the base layer due to errors; The leveling process should strictly control the elevation and slope, which can be adjusted in real time through hanging line measurement to ensure that the road surface flatness meets the specifications; During the maintenance period, it is necessary to implement road closure management, prohibit vehicles and pedestrians from entering, and regularly check the film coverage to prevent rapid evaporation of moisture from affecting the health effect.

　　冷再生機的價值，遠不止“舊路變新路”這么簡單——它讓每一寸舊水泥路面都得到充分利用，減少了建筑垃圾的產(chǎn)生與清運成本，單此一項就能為項目省下數(shù)十萬甚至上百萬；一體化的就地施工流程，省去了新集料采購、運輸?shù)拳h(huán)節(jié)，工期也比傳統(tǒng)方式縮短近半。這種既經(jīng)濟又環(huán)保的“黑科技”，正在讓更多舊路重獲新生，也為基建行業(yè)的綠色可持續(xù)發(fā)展提供了高效解決方案。若需了解具體項目的冷再生施工方案或設備選型，可咨詢專業(yè)技術團隊獲取定制化建議。

　　The value of a cold recycling machine is far more than simply transforming old roads into new ones - it allows every inch of old cement pavement to be fully utilized, reducing the generation and transportation costs of construction waste. This alone can save hundreds of thousands or even millions of dollars for the project; The integrated on-site construction process eliminates the need for new aggregate procurement and transportation, and shortens the construction period by nearly half compared to traditional methods. This "black technology" that is both economical and environmentally friendly is revitalizing more old roads and providing efficient solutions for the green and sustainable development of the infrastructure industry. If you need to know the specific cold recycling construction plan or equipment selection for a project, you can consult a professional technical team for customized advice.
