摘　　要：为明确沥青混合料拌和和易性的评价方法及研究现状,通过查阅国内外相关研究文献,对比分析各种不同的沥青混合料和易性评价方法、指标及研究结论,系统归纳了不同沥青混合料和易性评价方法的适用性及评价效果,并对拌和和易性的主要影响因素作出对比分析及综合评述。结果表明:沥青混合料拌和和易性的评价方法,大多是通过量化拌和过程中的阻力或能量消耗来构建相应的指标定量评价和易性,也有部分方法是通过压实体积指标或工作效能作为间接验证来评价和易性。混合料中材料组成及拌和条件直接影响沥青混合料的和易性,若提升和易性,不仅能够改善混合料的成型及压实性能,还能显著提升路面工程质量。不断优化和提升沥青混合料和易性评价方法以及相应评价指标,能够使混合料和易性得到更加精确合理的评价,这不仅有助于促进路面工程新技术的推广应用,还可以降低能量消耗、减少污染物与碳排放等。To clarify the evaluation methods and research status of mixing workability of asphalt mixture,by consulting relevant research literature in China and abroad and analyzing different evaluation methods,indexes,and research findings of the workability of asphalt mixture,the applicability and evaluation effects of different workability evaluation methods were systematically summarized,and the comparative analysis and comprehensive review were made on the main influencing factors of the mixing workability.The results show that in most evaluation methods for the mixing workability of asphalt mixture,corresponding indexes are constructed to quantitatively evaluate the workability by quantifying the resistance or energy consumption in the mixing process.Besides,in some other evaluation methods,workability can be evaluated by taking the compaction volume index or work effectiveness as indirect verification.The material composition and mixing conditions in the mixture directly affect the workability of the asphalt mixture.In addition,the improved workability can not only improve the forming and compaction performance of the mixture but also enhance the quality of road engineering.The improvement and enhancement of the evaluation method for the workability of asphalt mixture and the corresponding evaluation indexes can evaluate the workability of asphalt mixture more accurately and reasonably,which can promote the application of new road engineering technology and reduce energy consumption,pollutants,and carbon emissions.
