通过介绍沥青混合料离析的产生、机理以及评价方法,探讨了以目测法、最大理论密度、空隙率和图像分析技术判别混合料离析的可能性,并提出了判别沥青混合料离析的新方法。实践表明,该方法对路面施工具有一定的指导作用。 By introducing the generation, mechanism and evaluation method of segregation of asphalt mixture, the possibility of distinguishing the segregation of mixture by visual inspection, maximum theoretical density, porosity and image analysis is discussed. A new method of distinguishing asphalt mixture is proposed. Practice shows that this method has some guidance to pavement construction.
