再生材料的混合均匀性和级配受冷再生机械结构特性的影响。作为两种核心类型的铣刨机和混合机，沥青路面就地冷再生机和冷铣刨机发展同根同源技术与设备的应用有着相同的技术基础，但发展方向不同。
The mixing uniformity and gradation of recycled materials are affected by the structural characteristics of cold recycling machinery. As two core types of milling machines and mixers, asphalt pavement in situ cold recycling machine and cold milling machine have the same technical basis for the development of the same root and the application of the same source technology and equipment, but the development direction is different.
冷再生租赁是机器制造机的再生鼓，冷铣刨机的铣刨工作装置是铣刨鼓。两者都是由转子的旋转驱动，以便切割路面移入-然而，原地冷循环更有可能再生筒上的铣床布置调整了再生沥青混合料的粒径，保证了再生料的完全混合。并假设二次铣削时，滚筒外缘与铣床端部之间所形成的空间的合理性足以保证再生材料的均匀性和终分类。
The cold regeneration lease is the regeneration drum of the machine manufacturing machine, and the milling device of the cold milling machine is the milling drum. Both are driven by the rotation of the rotor, so that the cutting road surface can be moved in - however, the in-situ cold circulation is more likely. The layout of the milling machine on the regeneration cylinder adjusts the particle size of the recycled asphalt mixture, ensuring the complete mixing of the recycled asphalt. It is assumed that the space formed between the outer edge of the drum and the end of the milling machine is reasonable enough to ensure the uniformity and final classification of recycled materials during secondary milling.
冷再生机械沥青坡道的再生利用大致可分为五种类型：厂拌热再生、厂拌冷再生、就地热再生、就地冷再生和全厚式就地冷再生。他们有自己的优势，适合各种职业病合适的全厚度就地冷再生租赁是指连续完成铣磨、研磨、添加新材料、混合、分配、压实新旧材料的综合回收工艺，创建新基础在一般来说，再生处理深度为15-750px，深为30-1250px。
The recycling and utilization of asphalt ramp of cold recycling machinery can be roughly divided into five types: plant mixed hot recycling, plant mixed cold recycling, local geothermal recycling, local cold recycling and full thickness local cold recycling. They have their own advantages. The full thickness on-site cold regeneration lease suitable for various occupational diseases refers to the comprehensive recycling process of continuously milling, grinding, adding new materials, mixing, distributing and compacting new and old materials, creating a new foundation. Generally speaking, the depth of regeneration treatment is 15-750px, and the depth is 30-1250px.
充分利用旧路面砖，降低了道路养护过程中路面材料的开挖、运输、垃圾处理、新材料采购等费用，降低了冷再生机械租赁费用减少。In一般来说，成本可以是20%-40%。厚度越小，可以降低的成本就越多重要的材料：水泥、水、少量新骨料、石灰(早期固体)等等采用水泥作为黏结剂是一种实用、廉价、快速且类似于半刚性基层的成熟技术。
Make full use of old pavement bricks, reduce the costs of excavation, transportation, garbage disposal, new material procurement, etc. of pavement materials in the process of road maintenance, and reduce the rental costs of cold recycling machinery. In general, the cost can be 20%-40%. The smaller the thickness, the more cost can be reduced. For important materials: cement, water, a small amount of new aggregate, lime (early solid), etc., using cement as a binder is a practical, cheap, fast and mature technology similar to semi-rigid base.
