In daily life, we often see road construction and maintenance. When repairing a road, the road is sealed first, followed by retaining wall masonry, lime powder filling, drainage ditch construction, concrete cold recycling, water stable pavement construction, asphalt cold recycling, road asphalt pavement construction, slope greening repair, and later road markings painting. After a distance, it is successful. During the road construction process, some advanced scientific and technological production processes will be used, mainly including concrete cold recycling and asphalt cold recycling. What are the main differences between concrete cold recycling and asphalt cold recycling? Cold recycling rental manufacturers will introduce to you:

水泥冷再生

Cement cold regeneration

混凝土冷再生灵活运用废弃原材料，并按占比添加一定量的添加剂在自然环境溫度下就地持续地完成原材料的铣刨、粉碎、拌和、路面施工及夯实成形，进而修建出具备需要特性品质的新基层。

Cold recycling of concrete flexibly utilizes waste raw materials, and adds a certain amount of additives in proportion to continuously complete the milling, crushing, mixing, road construction, and compaction of raw materials on-site at natural environmental temperatures, thereby building a new base layer with the required characteristics and qualities.

与传统式工程施工方式对比，混凝土冷再生低成本、率、性价比高，可降低环境污染。

Compared with traditional engineering construction methods, cold recycling of concrete has the advantages of low cost, high efficiency, and high cost-effectiveness, which can reduce environmental pollution.

沥青道路冷再生将旧路铣刨、脱离所得的回收沥青道路原材料，经粉碎筛分，抽提测量油石比、矿料级配构成及回收沥清的性能参数后，按新的沥清再造混和料配合比设计，适度添加一部分新骨料、水、乳化沥青等，在常温下标准下（不加热）拌和新的沥青道路原材料。冷再生技术性能够降低成本10-20%左右，且生产率高。

Cold recycling of asphalt roads involves milling and separating the old roads to obtain recycled asphalt road raw materials. After crushing and screening, the asphalt to stone ratio, mineral aggregate gradation composition, and performance parameters of recycled asphalt are extracted and measured. The mixture is designed according to the new asphalt recycling mixture ratio, with a moderate addition of new bone materials, water, emulsified asphalt, etc., and the new asphalt road raw materials are mixed at room temperature (without heating). Cold regeneration technology can reduce costs by about 10-20% and has high productivity.

沥清冷再生技术性推动了工业生产废弃物的开发利用与再生能源的综合利用，同时推动了原材料再造和能源取代等新技术应用、新技术新工艺的开发设计与科学研究。

The technology of asphalt cold recycling has promoted the development and utilization of industrial production waste and the comprehensive utilization of renewable energy, while also promoting the application of new technologies such as raw material recycling and energy substitution, as well as the development, design, and scientific research of new technologies and processes.

沥青道路冷再生技术性的运用对维护绿色生态、绿色可持续性发展趋势的环境效益更显，对改进道路生态具备关键作用。

The application of cold recycling technology in asphalt roads has more significant environmental benefits for maintaining green ecology and sustainable development trends, and plays a key role in improving road ecological and environmental protection.
