摘　　要：为进一步促进交通领域“碳中和”目标的实现,针对国内外温拌沥青技术的研究现状,总结了温拌沥青技术节能减排的优势及其局限性,研究了常用温拌剂和温拌技术的降温降黏机理及不同温拌技术对其性能的影响,综述了温拌技术在改性沥青混合料、再生沥青混合料及其他沥青混合料中的最新研究进展,分析了温拌技术在改性沥青混合料和再生沥青混合料中应用时降低施工温度带来的节能减排效果,探讨了降温对沥青混合料高温性能、低温性能、水稳定性和疲劳性能等的影响。研究结果表明:温拌技术具有绿色环保、节能减排和便于施工等优点,但仍存在温拌剂成本高和温拌沥青中残留水分对其性能产生不利影响的问题;常用温拌技术多为国外技术专利,在国内经过研究、消化和吸收后在各种沥青混合料中得到广泛应用,充分了解温拌技术作用机理对开发低能耗、低排放和低成本的温拌沥青材料和技术至关重要;温拌技术应用在改性沥青混合料、再生沥青混合料和其他沥青混合料中能降低施工时的黏度和温度,节能减排效果显著,而限制其在工程中推广应用主要是由于前期投入成本较高,混合料低温性能和水稳性能不足;探索温拌技术与其他类型沥青混合料相结合的方案有利于促进绿色公路的创新与发展。总之,温拌沥青技术是全球“碳中和”目标实现的必然发展趋势,也是满足绿色公路发展理念的重要方法之一。To further promote the carbon neutrality in the field of transportation,the advantages and limitations of the warm mixing asphalt technology were summarized in terms of energy conservation and emission reduction according to the research status in China and abroad.The temperature and viscosity reduction mechanisms of common warm mixing agents and warm mixing technologies and the influences of different warm mixing technologies on their properties were studied.The latest research progress of warm mixing technology in the modified asphalt mixture,recycled asphalt mixture,and other asphalt mixtures was reviewed.The effectiveness of energy conservation and emission reduction under reducing the construction temperature was analyzed when the warm mixing technology was applied in the modified asphalt mixture and recycled asphalt mixture.Then,the impacts of temperature reduction on the high-temperature performance,low-temperature performance,water stability,and fatigue performance of asphalt mixture were discussed.Research results show that the warm mixing technology has such advantages as environmental friendliness,energy conservation,emission reduction,and construction facilitation.However,it has also some drawbacks such as the high cost of warm mixing agent and the residual moisture in the warm mixing asphalt which exerts adverse effects on its performance.The commonly used warm mixing technology is mostly patented abroad,and it has been widely used in various asphalt mixtures after research,digestion,and absorption in China.Fully understanding the mechanism of warm mixing technology is crucial to the development of warm mixing asphalt materials and technologies characterized by low energy consumption,low emission,and low cost.The application of warm mixing technology in the modified asphalt mixture,recycled asphalt mixture,and other asphalt mixtures can reduce the viscosity and temperature during the construction,with remarkable effects of saving energy and reducing emission.The limitation factors of its application
