| 摘 要： | 从理论上对沥青路面空隙结构进行了分析,提出了均布系数、当量半径、连通率、曲折度等指标,辅以空隙率全面评定空隙结构特征。还分析了影响空隙结构特征的诸多影响因素。以OGFC混合料为例,计算并分析其空隙结构特征。为研究水在沥青路面空隙中的输送过程奠定基础,对沥青路面抗水损坏性能提高具有指导作用。

| Abstract: | This paper theoretically analyzed the void structure of asphalt pavement,and proposed the uni-form distribution coefficient,equivalent radius,connectivity,tortuosity and other indicators,supplemented by the void ratio to assess the void structure characteristics comprehensively.It also analyzed the influence factors of void structure characteristics.Combined with the example of OGFC mixture,it calculated and analyzed the void struc-ture characteristics etc. for reference. |
