Permeability Model of Porous Asphalt Mixture

  • 摘要: 利用cosmos图像分析软件对大空隙沥青混合料试件切片进行图像分析,获取空隙半径、空隙间距等空隙参数用以确定大空隙沥青混合料渗透模型网格的划分及初始数值的输入,采用蒙特卡罗(Monte Carlo)方法建立渗透模型,根据Hagen-Poiseuille原理及松弛迭代法建立数学模型.结果表明,数值模拟渗透结果与室内渗透试验结果具有一致性,该模型可以模拟不同水头高度下任意最大骨料粒径、任意开级配的大空隙沥青混合料的渗透系数,为大空隙沥青混合料设计提供了有效方法.
    Abstract: The void parameters such as void radius and void space are achieved by image analysis of porous asphalt mixture sample slice through cosmos image analyzing software,so as to set up the grid sizing of the permeability model of the porous asphalt mixture and the input of original value. The method of Monte Carlo is used to set up the permeability model. The mathematics model abstracted is based on the Hagen-Poiseuille theory and the flab iterative method. The result shows that the numerical simulation permeability outcome is consistent with the indoor permeability test outcome. The model can simulate any maximum congregate diameter at different water surface levels and the permeability coefficient of any open-graded porous asphalt mixture. The model offers an effective method for designing of the porous asphalt mixture.
