| 摘 要： | 为寻找一种既能对级配离析又能对温度离析进行评价的离析评价方法，采用一种网格法将沥青路面分成正常区和加密区2个不同的区域，并对其渗水系数进行分析，提出一个以渗水系数作为离析评价指标的综合离析评价方法。依据2个不同区域测定的渗水系数，确定4类离析程度的判断标准。

| Abstract: | In order to look for an segregation evaluation method to evaluate both grading segregation and temperature segregation, this paper adopts grid-based method to divide asphalt pavement into 2 different areas, i.e. normal area and encrypted area and analyzes its water permeability coefficient, and further proposes an integrated segregation evaluation method with water permea.bility coefficient as segregation evaluation index. On the basis of water permeability coefficients measured in 2 different areas, the paper determines judgment standards for 4 segregation degrees. |
