摘要
对沥青混合料马歇尔试件进行冻融劈裂试验,获取试件初始和冻融劈裂后内部结构的CT图像,分析冻融劈裂前后试件内部结构特性的变化,研究其对沥青混合料微观结构的影响。
The freeze - thaw clavage test is carried out for Marchall sample of asphalt mixture, and CT image of internal structure at the begining of sample and after its freeze - thaw is gained. The paper analyzes the sample change in internal structure before and after freeze- thaw clavage,and examites its influence on microscopic structure of asphalt inixture.
