Abstract
Based on CT technology, real-time scanning and observing meso-damage evolution of emulsified asphalt concrete was carried out. With methods of visual analysis, CT number analysis and damage variable analysis, the following conclusions were obtained: during the continuous loading, the change of CT average value was little at the upper part of cross-sections, but that of the lower part of cross-sections was significant and its damage was serious. Concrete specimen experienced four stages of compaction, dilatancy, crack propagation and failure. Plastic characteristics was revealed in failure process, which due to the mechanical properties of emulsified asphalt concrete, that is the lower strength and lower elastic modulus.
