| 摘 要： | 对沥青混合料离析评价方法的研究现状进行了回顾，并基于数字图像处理技术，对沥青混合料中集料的分布状态进行了直接研究，借此评价离析程度。研究结果表明：通过比较截面上一定区域内集料面积累计之和的差异，可以定量地评价沥青混合料的离析程度。

| Abstract: | The present methods for evaluating segregation in hot-mix asphalt were reviewed, and on the basis of digital image processing, the aggregate distribution in hot-mix asphalt, by which to assess the level of segregation, was studied directly in this paper. The research results indicate that if the differences between cumulative aggregate area values across proper regions on a section are considered, it is feasible to assess quantitatively the level of segregation in hot-mix asphalt. |
