冷再生與銑刨是兩種不同的路面維修工藝，它們在工作原理、使用場景和作用效果上存在顯著差異。以下是它們的主要區(qū)別：

　　Cold recycling and milling are two different road maintenance processes, which have significant differences in their working principles, usage scenarios, and effects. Here are their main differences:

　　1. 工作原理：冷再生拌和機通過將路面破碎并經過篩分、混和等環(huán)節(jié)進行再生處理，能夠將質量較差的舊路面轉化為具有一定強度和合適粒徑的新料，這些新料可用于新的路面結構層。而銑刨機通過設置的刀具將瀝青路面刨下來，可選用硬質合金刀頭和鋸齒刀頭進行不同程度的切削，主要目的是去除路面病變層，同時將路面表面加工成為一定粗度，以便噴涂新瀝青混合料。

　　1. Working principle: The cold recycling mixer can transform poor quality old road surfaces into new materials with certain strength and suitable particle size by crushing the road surface and performing recycling treatment through screening, mixing and other processes. These new materials can be used for new road structure layers. The milling machine grinds off the asphalt pavement through the set cutting tools, which can use hard alloy cutting heads and serrated cutting heads for different degrees of cutting. The main purpose is to remove the pavement lesion layer and process the pavement surface into a certain roughness for spraying new asphalt mixture.

　　2. 使用場景：冷再生拌和機適用于對舊路面進行再生加工。再生后的瀝青混合料質量與新瀝青混合料相當，可與新料一起使用，廣泛應用于現(xiàn)代高速公路的建設中。而銑刨機多用于舊路面的切削去除，例如清理路面漏洞、瀝青路面表面的陳舊斑塊等缺陷。它屬于粗加工設備，在公路、城鎮(zhèn)道路、機場、貨場等瀝青混凝土面層的開挖翻新中有廣泛應用。

　　2. Usage scenario: The cold recycling mixer is suitable for recycling old road surfaces. The quality of the regenerated asphalt mixture is equivalent to that of the new asphalt mixture, and it can be used together with the new material, which is widely used in the construction of modern highways. However, milling machines are often used for cutting and removing old road surfaces, such as cleaning up road holes, old patches on asphalt road surfaces, and other defects. It belongs to rough processing equipment and is widely used in the excavation and renovation of asphalt concrete surfaces such as highways, urban roads, airports, and freight yards.

　　3. 施工組織：銑刨施工現(xiàn)場機械一般為銑刨機、自卸車(接受銑刨舊瀝青料用)和灑水車，人員用量也比較少。施工組織比較簡單。而泡沫瀝青冷再生的施工組織需要人工數(shù)量較多。整個施工要求必須采用流水作業(yè)法，各工序緊密銜接，各材料用量及組織嚴密程度對施工質量影響很大。整個施工組織要求較高。

　　3. Construction organization: The machinery used for milling and planing construction sites is generally milling machines, dump trucks (used to accept milling and planing old asphalt materials), and sprinkler trucks, with relatively low personnel usage. The construction organization is relatively simple. However, the construction organization of foam asphalt cold recycling needs more manpower. The entire construction requires the use of assembly line operation method, with each process closely connected. The amount of materials used and the degree of organization have a significant impact on the construction quality. The overall construction organization requires high standards.

　　4. 施工效果：銑刨可以清除路面的擁包、油浪、網紋、車轍等。為新舊面的更好結合良好起拉毛作用。由于對瀝青路面下面層有擾動因素，其強度會產生影響，不能改善基礎狀況。而泡沫瀝青冷再生混合料增加了粒料的剪切強度，降低了水敏感性。原路面材料全部重復利用，不產生新的建筑垃圾，節(jié)省運輸費用，減少因開采料場和開挖土基所造成的粉塵污染，有利于環(huán)境保護。

　　4. Construction effect: Milling can remove road bumps, oil waves, mesh patterns, ruts, etc. To achieve a better combination of old and new surfaces, it has a good pulling effect. Due to disturbance factors on the lower layer of asphalt pavement, its strength will be affected and cannot improve the foundation condition. However, foam asphalt cold recycled mixture increases the shear strength of granular materials and reduces the water sensitivity. All raw road materials are reused, without generating new construction waste, saving transportation costs, reducing dust pollution caused by mining material yards and excavating soil foundations, and benefiting environmental protection.
