冷再生機作為道路養護領域的 “綠色利器”，憑借現場修復、舊料再利用等優勢，大幅降低施工對環境的影響。然而，這并不意味著它能 “隨心所欲” 作業。從場地條件到氣候因素，從周邊生態到施工規范，冷再生機租賃的實際應用，需要與環境達成微妙的 “默契”。

　　As a "green weapon" in the field of road maintenance, the cold recycling machine greatly reduces the impact of construction on the environment by virtue of its advantages such as on-site repair and reuse of old materials. However, this does not mean that it can do homework "as it pleases". From site conditions to climate factors, from surrounding ecology to construction standards, the practical application of cold recycling machine leasing requires a subtle "tacit understanding" with the environment.

　　一、場地基礎：穩定作業的 “先天條件”

　　1、 Site foundation: the "innate condition" for stable operation

　　冷再生機的正常運行對施工場地有著硬性要求。首先，場地需具備足夠的承載能力，尤其是大型履帶式冷再生機，整機重量可達數十噸，松軟、泥濘的地面會導致設備下陷，影響銑刨與拌合精度，甚至造成機械損壞。因此，施工前需對場地進行壓實處理，必要時鋪設碎石或鋼板作為臨時路基。其次，作業空間要充足，冷再生機在銑刨、運輸、攤鋪等環節需要回轉、進退空間，狹窄的街巷或周邊障礙物過多的區域，可能限制設備操作，增加施工難度與安全風險。此外，場地內的水電供應也需穩定，雖然冷再生機自帶動力系統，但拌合環節需要大量用水，且夜間施工可能涉及照明用電，提前規劃好水電接入點至關重要。

　　The normal operation of the cold recycling machine has strict requirements for the construction site. Firstly, the site needs to have sufficient load-bearing capacity, especially for large tracked cold recycling machines, which can weigh tens of tons. Soft and muddy ground can cause equipment to sink, affecting milling and mixing accuracy, and even causing mechanical damage. Therefore, the site needs to be compacted before construction, and if necessary, crushed stones or steel plates should be laid as temporary roadbeds. Secondly, the workspace should be sufficient. The cold recycling machine needs to have space for rotation, advance and retreat during milling, transportation, paving and other processes. Narrow streets or areas with too many obstacles may limit equipment operation, increase construction difficulty and safety risks. In addition, the water and electricity supply within the site also needs to be stable. Although the cold recycling machine has its own power system, the mixing process requires a large amount of water, and nighttime construction may involve lighting electricity. It is crucial to plan the water and electricity access points in advance.

　　二、氣候因素：與天氣的 “時間博弈”

　　2、 Climate factors: the 'time game' with weather

　　冷再生機的施工效果與氣候條件緊密相關。雨天是冷再生作業的 “大敵”，雨水會稀釋再生劑，降低新舊材料的粘結強度，導致再生層壓實度不足，后期易出現松散、坑洼等病害。因此，在租賃冷再生機前，需密切關注天氣預報，避免在降雨前后 48 小時內施工；若遇突發降雨，需立即停止作業，覆蓋未壓實的再生層，防止雨水滲透。低溫環境同樣影響施工質量，當氣溫低于 5℃時，再生劑與瀝青的活性降低，混合料難以壓實成型，此時需采取加熱措施（如預熱舊料、添加溫拌劑），或暫停施工。相比之下，晴朗、微風的天氣最適宜冷再生作業，既能保證材料干燥，又利于減少粉塵擴散。

　　The construction effect of the cold recycling machine is closely related to the climatic conditions. Rainy days are the "enemy" of cold recycling operations. Rainwater dilutes the regeneration agent, reduces the bonding strength between new and old materials, and leads to insufficient compaction of the regeneration layer, which can easily cause diseases such as looseness and potholes in the later stage. Therefore, before renting a cold recycling machine, it is necessary to closely monitor the weather forecast and avoid construction within 48 hours before and after rainfall; In case of sudden rainfall, the operation should be stopped immediately and the uncompacted regeneration layer should be covered to prevent rainwater infiltration. Low temperature environment also affects construction quality. When the temperature is below 5 ℃, the activity of the rejuvenator and asphalt decreases, and the mixture is difficult to compact and form. At this time, heating measures (such as preheating old materials, adding warm mix agents) or suspending construction are needed. In contrast, clear and gentle weather is most suitable for cold recycling operations, which can ensure material dryness and reduce dust dispersion.

　　三、生態保護：綠色施工的 “底線約束”

　　3、 Ecological Protection: The 'Bottom Line Constraint' of Green Construction

　　冷再生機雖以環保著稱，但施工過程仍需嚴守生態保護紅線。首先是粉塵控制，銑刨舊路面時會產生大量揚塵，若不加以處理，不僅污染空氣，還可能影響周邊居民健康。因此，設備需配備高效的除塵裝置，如霧炮機、吸塵管道，實時抑制粉塵；運輸車輛需封閉嚴密，避免遺撒造成二次揚塵。其次，施工產生的廢水（如清洗設備、拌合剩余的污水）含有瀝青、再生劑等污染物，不可直接排放，需設置沉淀池進行過濾處理，達標后方可排放或循環利用。此外，冷再生機運行時會產生噪音，在居民區、學校周邊施工時，需嚴格遵守當地噪音管控規定，避開居民休息時間，或采取加裝隔音屏障等降噪措施。

　　Although the cold recycling machine is known for its environmental friendliness, the construction process still needs to strictly adhere to the ecological protection red line. Firstly, dust control is important. When milling and planing old road surfaces, a large amount of dust is generated. If not treated properly, it not only pollutes the air but may also affect the health of surrounding residents. Therefore, the equipment needs to be equipped with efficient dust removal devices, such as fog cannons and suction pipes, to suppress dust in real time; Transport vehicles need to be tightly sealed to avoid secondary dust caused by scattering. Secondly, the wastewater generated during construction (such as cleaning equipment and residual mixing wastewater) contains pollutants such as asphalt and rejuvenators, which cannot be directly discharged. A sedimentation tank needs to be set up for filtration treatment, and can only be discharged or recycled after meeting the standards. In addition, the operation of the cold regeneration machine will generate noise. When constructing in residential areas or around schools, it is necessary to strictly comply with local noise control regulations, avoid residents' rest time, or take noise reduction measures such as installing sound barriers.

　　四、周邊環境：與社區的 “和諧共處”

　　4、 Surrounding environment: harmonious coexistence with the community

　　冷再生機施工還需兼顧周邊社區的生產生活需求。在城市主干道、商業區等交通繁忙區域作業時，需合理規劃施工時段與交通疏導方案，避免因長時間封路造成交通擁堵；可采用半幅施工、夜間施工等方式，減少對交通的影響。若周邊有醫院、精密儀器工廠等對振動敏感的場所，需評估冷再生機作業產生的振動是否會造成干擾，必要時調整施工工藝或更換低振動設備。此外，施工前需與周邊居民、商戶充分溝通，公示施工計劃與環保措施，爭取理解與支持，避免因環境問題引發糾紛。

　　The construction of cold recycling machines also needs to take into account the production and living needs of surrounding communities. When working in busy traffic areas such as urban main roads and commercial districts, it is necessary to plan the construction period and traffic diversion plan reasonably to avoid traffic congestion caused by long-term road closures; Half width construction, nighttime construction, and other methods can be used to reduce the impact on traffic. If there are hospitals, precision instrument factories and other places sensitive to vibration in the surrounding area, it is necessary to evaluate whether the vibration generated by the cold regeneration machine operation will cause interference, and adjust the construction process or replace low vibration equipment if necessary. In addition, it is necessary to fully communicate with surrounding residents and merchants before construction, publicize the construction plan and environmental protection measures, strive for understanding and support, and avoid disputes caused by environmental issues.
