由于受到水的作用和影响,沥青混合料马歇尔试件在冻融劈裂试验前后包括空隙大小、分布等在内的内部微观结构发生了变化,文章利用CT技术对试件进行了扫描,从CT图像方面分析了试件的初始结构和冻融劈裂试验后的结构。
Due to the effect of water, the internal microstructure of asphalt mixture Marshall specimens before and after the freeze-thaw splitting test including the size and distribution of voids changed. The CT scanning technique was used to scan the specimens. Image analysis of the initial structure of the specimen and freeze-thaw splitting after the test structure.
