摘要
交通基础设施建设属于高能耗、高排放行业,为努力实现碳达峰与碳中和目标,温拌沥青技术受到广泛关注。该技术可有效降低沥青混合料的拌和与摊铺温度,从而达到降低能耗、减少有害气体排放的目的,符合绿色发展理念。本文对国内外有关温拌沥青技术的研究现状进行了较为全面的阐述,内容涉及温拌沥青技术种类和作用机制,并从高低温性能、水稳定性能、抗疲劳性能和抗老化性能等方面进行论述,对比分析了不同类型温拌剂对沥青混合料路用性能的影响规律。最后总结了温拌技术应用现状,并对今后的发展方向进行了展望。
The construction of transportation infrastructure is a high-energy consumption and high-emission in-dustry.To strive for the goals of carbon peak and carbon neutrality,warm mix asphalt technology has garnered significant attention.This technology effectively reduces the mixing and paving temperatures of asphalt mix-tures,thereby lowering energy consumption and harmful gas emissions,aligning with the concept of green de-velopment.This article provides a comprehensive overview of the current state of research on warm mix asphalt technology both domestically and internationally,covering the types and mechanisms of warm mix asphalt tech-nology.It discusses high and low-temperature performance,water stability,fatigue resistance,and aging resis-tance,and compares the effects of different types of warm mix additives on the performance of asphalt mixtures.Finally,it summarizes the current application status of warm mix technology and outlines future development directions.
