沥青混合料微观力学分析综述

Review on asphalt mixture micromechanics analysis

胡霞光 

摘 要:针对当前沥青混合料研究方法的局限性,分析了国内外该领域的研究现状与存在问题.介绍了沥青混合料数字化方法及常用的力学分析方法.给出了运用微观力学方法研究沥青混合料的基本思路,即以二维和三维混合料数字图像为基础,数字重构沥青混合料微观结构,研究基于微观力学的沥青混合料集料接触模型,建立基于离散元的混合料微观空间结构的力学模型,应用离散元方法和微观力学理论分析该模型在劲度模量试验中的力学行为,进行沥青混合料劲度模量的虚拟试验.通过试验检验与校准,得出具有高可靠性、高精确度的劲度模量力学预估方法.
