摘　　要：为实现沥青混合料设计、施工与服役期间的性能一体化,引入沥青混合料工作性能指标,从黏聚性、黏附性、流动性、可压实性和均匀性5个方面分析其对混合料工作性能的影响特征。首先分别阐述了上述5个方面各自的评价方法与指标,总结了现有评价体系的不足与未来研究方向;其次,综合分析了上述5个方面之间的内在联系及其对混合料路用性能的影响规律;最后,基于沥青混合料的工作性能与路用性能,提出合理、便捷且具有代表性的沥青混合料工作性能综合评价方法及指标,并将该综合指标嵌入设计阶段,提出基于工作性能与路用性能的沥青混合料平衡设计法,以此来调整和优化沥青混合料的设计,推动沥青混合料设计方法的完善与升级,促进沥青路面的可持续与高质量发展。To achieve the integrated performance of asphalt mixtures throughout their design,construction,and service-life periods,this study introduces workability indicators and analyzes their effects on the workability of asphalt mixtures from the following five aspects:cohesion,adhesion,flowability,compactability,and homogeneity.First,the evaluation methods and indicators for each of the five aspects are elaborated separately,and the disadvantages of the existing evaluation system and future research directions are summarized.Second,the intrinsic relationship between the abovementioned five aspects and their effect on the pavement performance of asphalt mixtures are comprehensively analyzed.Finally,based on the workability and pavement performance of asphalt mixtures,a rational,convenient,and highly representative comprehensive evaluation method as well as an indicator for the workability of asphalt mixtures are proposed.This comprehensive indicator is incorporated into the design phase,and a balanced mix-design method based on workability and pavement performance is proposed to adjust and optimize the design of asphalt mixtures.This can promote both the improvement and upgrading of asphalt-mixture design methods as well as the sustainable and high-quality development of asphalt pavements.
