The mechanical, mesodamage, and the microproperties of cement-emulsified asphalt concrete have been investigated by\ncomputed tomography (CT), scanning electron microscopy (SEM), X-ray diffraction (XRD), and thermogravimetric analysis\n(TG) in this work. Emulsified asphalt delayed the hydration of cement, making the early compressive strength of concrete develop\nslowly. However, the concrete compressive strength increased rapidly with the demulsification of emulsified asphalt. The damage\nstages of condense, expansion of volume, rapid crack propagation, and damage by real-time scanning have been observed. The CT\nmean value of the place near the lower end face suffered a larger decline but a smaller decline to the upper part of the sample. The\nevolution of concrete suffering damage to failure is a gradual development process, and no sharp expansion of brittle failure. The\nunhydrated cement, incorporation asphalt, fibrous Cââ?¬â??Sââ?¬â??H gel, CH, needle-shaped ettringite, and other hydration products were\ninterwoven to constitute emulsified asphalt-cement paste, forming a spatial structure.
