沥青路面的就地冷再生通常在常温下进行，通过现场铣刨、破碎并添加再生结合料，形成新的道路基层。

The on-site cold recycling of asphalt pavement is usually carried out at room temperature, through on-site milling, crushing, and adding recycled binders to form a new road base.

施工前准备与病害处理：对旧路结构状况进行调查并铺筑试验路。将旧路面清扫干净，对明显的沉陷、坑槽、翻浆等病害进行填平处理。

Preparation and disease treatment before construction: Investigate the structural condition of the old road and pave a test road. Clean up the old road surface and fill in obvious defects such as subsidence, potholes, and frost heave.

添加新料与结合料：根据设计要求，人工或机械摊铺新集料（如碎石）、水泥或石灰等添加剂。随后，冷再生机推动稀浆车或水车行进，在铣刨破碎的同时，精准添加水及再生剂（如乳化沥青、泡沫沥青等）。

Add new materials and binders: According to design requirements, manually or mechanically spread new aggregates (such as crushed stone), cement or lime additives. Then, the cold recycling machine drives the slurry truck or water truck, and accurately adds water and recycling agents (such as emulsified asphalt, foam asphalt, etc.) while milling and crushing.

就地铣刨与拌和：冷再生机对旧路面进行切削、破碎，并将旧料、新集料、结合料及水在现场进行充分拌和。作业时需严格控制再生深度、行进速度（一般为4~12m/min）及含水量。

On site milling and mixing: The cold recycling machine cuts and crushes the old road surface, and thoroughly mixes the old materials, new aggregates, binders, and water on site. Strictly control the regeneration depth, travel speed (usually 4-12m/min), and moisture content during homework.

摊铺与找平：拌和后的混合料可由冷再生机直接传输至摊铺机料斗进行同步摊铺，或使用推土机初找平后，使用平地机刮平至设计高程与线形。

Paving and Leveling: The mixed material can be directly transported to the hopper of the paver by a cold recycling machine for synchronous paving, or after initial leveling with a bulldozer, it can be leveled with a grader to the design elevation and line shape.

碾压与压实：检测混合料含水量，必要时补水。使用大吨位压路机（如单钢轮、双钢轮及胶轮压路机）按照“初压、复压、终压”的顺序进行碾压，确保压实度达标。

Rolling and compaction: Check the moisture content of the mixture and add water if necessary. Use large tonnage rollers (such as single steel wheel, double steel wheel, and rubber wheel rollers) to compact in the order of "initial compaction, secondary compaction, and final compaction" to ensure that the compaction degree meets the standard.

养生与面层铺筑：碾压完成后进行保湿养生（通常不少于7天），期间封闭交通。养生期满且强度达标后，方可铺筑新的沥青面层。

Health preservation and surface layer paving: After compaction is completed, moisturizing and health preservation should be carried out (usually not less than 7 days), and traffic should be closed during this period. After the health preservation period has expired and the strength meets the standard, a new asphalt surface layer can be laid.
