摘要
对沥青路面心样开展饱水疲劳实验,通过CT扫描技术,采用数字图像处理技术,分析沥青路面水破坏过程中试件内部结构的变化趋势。结果表明:在饱水疲劳试验中,随着加载次数的增加,心样的孔隙和集料面积逐渐增加,而沥青胶浆面积逐渐减少,形象地反映了试件水破坏的机理,即沥青混凝土的粘附性损坏过程。
Based on CT （Computerized Tomograph） technology, the water damage process of asphalt concrete was studied through fatigue experiment. According to CT image processing result, the change tendency of interior structure was analyzed in the process of saturation water fatigue experiment of asphalt concrete. The result indicates that, in the saturation water fatigue experiment, with the loading times increase, the void and the aggregate area increases gradually, and the mastic asphalt area reduces gradually, which reflects water damage mechanism of the asphalt samples, namely the asphalt concrete cohesion damage.
