| 摘 要： | 为了解决目前国内缺乏离析评价方法与评价指标的问题。在大量调查国内外资料基础上，分析运用构造深度来评价沥青混合料离析的可能性。在各种构造深度测试方法中，以激光断面仪最为有效快速。采用离析区域构造深度与均匀区域构造深度比值作为离析评价指标．得出了不同程度离析的砰价标准。针对均匀区域构造深度难以测定的问题，提出了几种均匀区域构造深度的预测模型。研究表明，应用构造深度评价沥青混合料离析是可行的。

| Abstract: | On the conditions the evaluation method and evaluation index of segregation are lacked in China, trial of texture depth is made to evaluate segregation. Several methods for measuring the texture depth are compared, Laser Surface Texture Measurement is the most useful and rapid . The texture ratio between segregated area and non-segregated area is used as the evaluation index of segregation, the evaluation criteria of different level segregation is obtained. Several prediction models of non-segregated texture depth are analyzed. The results of research show that it is feasible to apply texture depth to evaluate segregation. |
