摘要
为了揭示级配对级配碎石渗透系数的影响规律,采用沥青路面渗水系数的测试设备,分析最大粒径、空隙率对渗透系数的影响,对确定云南高海拔地区合理的级配碎石具有重要的参考价值。
The impact of maximum grain size and porosity on permeability coefficient are analyzed using asphalt pavement seepage coefficient test equipment in order to reveal the influence law of gradation on graded gravel permeability coefficient,which have important reference value for the determination of reasonable graded broken stone in Yunnan high-altitude areas.
