摘　　要：路面材料的渗透系数可作为路面结构内部排水设计以及评价路面施工质量的依据,文章研制了一种测定路面钻芯取样试件渗透系数的新装置,提出了相应的试验方法.通过对云南某高速公路现场钻芯取样试件的渗透试验研究,证明渗透试验装置和方法是可行的,并对测试结果进行了分析.The permeability coefficient of the pavement material is a very important parameter in drainage designing the of pavement structure, which is also used to evaluate the quality of road construction. New equipment is used to measure the permeability coefficient of the pavement drilling core sample and the relevant testing methods are introduced. It is proved to be feasible by testing the drilling core sample from a certain highway of Yunnan province. The test result is also analyzed.
