废旧沥青混合料分离再生应用技术

Technology of Waste Asphalt Mixture Separate Recycling

结合传统再生技术的优缺点,提出了废旧沥青混合料新的再生技术———分离式再生。分析了再生沥青混合料的高温稳定性、低温性能和水稳定性等路用性能。研究结果表明:废旧沥青混合料分离式再生集料满足使用要求,分离式再生集料拌制的再生沥青混合料具有良好的路用性能。

Combined with the advantages and disadvantages of traditional recycling technologies, a new recycling technology for old asphalt mixture, separate recycling, was put forward. The high temperature performance, low-temperature performance and water stability of recycled asphalt mixture were analyzed. The results show that the separate recycled aggregates can meet application requirements, and the asphalt mixture has good road performance.
