摘　　要：沥青材料在拌和、运输以及摊铺阶段会释放大量的固体颗粒物与有害气体,统称为沥青烟气。为缓解沥青烟气的不良影响,推动绿色交通快速发展,国内外学者主要从沥青烟气的室内外检测方法、释放特性以及抑制措施等方面展开了广泛研究。由于不同学者采用烟气检测方法和评价指标的差异,导致检测数据和评价结果的相关性较低;同时,在沥青烟气生成机理以及烟气抑制机制方面缺乏系统性研究,使得抑烟沥青在抑制效果与路用性能方面存在不足。本文综述了沥青烟气的国内外研究现状,总结归纳了现有的沥青烟气检测方法,并对比了各检测方法的优缺点及适用范围,从沥青种类、温度与加热时间三个方面阐述了沥青烟气的释放特性,对比分析了各类抑制措施的烟气抑制效果及抑制机理,最后提出了未来沥青抑烟技术应从开发高效规范的烟气检测技术、探究烟气中各物质的演变机制与转化关系、研发新型复合多孔抑制材料以及环境效益与健康风险评估等方面开展研究,为实现沥青烟气高效减排奠定基础。Asphalt materials will release a large amount of solid particles and harmful gases during the mixing,transportation and paving stages,collectively known as asphalt fumes.In order to alleviate the adverse effects of asphalt fumes and promote the rapid development of green transportation,domestic and foreign scholars have carried out extensive research on the indoor and outdoor detection methods,release characteristics and suppression measures of asphalt fumes.Due to the differences in fumes detection methods and evaluation indicators adopted by different scholars,the correlation between detection data and evaluation results is low.Additionally,there is a lack of systematic research on the formation mechanism of asphalt fumes and the mechanism of fumes suppression,which makes the fumes suppression asphalt insufficient in terms of inhibition effect and road performance.This paper reviewed the research status of asphalt fumes at home and abroad,summarized the existing asphalt fumes detection methods,and compared the advantages and disadvantages of each detection method and the scope of application.The release characteristics of asphalt fumes were described from three aspects:asphalt type,temperature and heating time.The fumes suppression effect and suppression mechanism of various suppression measures were compared and analyzed.Finally,it was proposed that the future asphalt fumes suppression technology should be studied from the aspects of developing efficient and standardized fumes detection technology,exploring the evolution mechanism and transformation relationship of various substances in fumes,developing new composite porous suppression materials,and environmental benefits and health risk assessment,which laid a foundation for achieving efficient emission reduction of asphalt fumes.
