▎ 摘  要

NOVELTY - The method involves using dynamic shear rheometer to perform stress scanning graphene to the micro-cap asphalt mortar, taking stress as horizontal coordinate, drawing the dynamic modulus-stress relation curve of the longitudinal coordinate drawing graphene of the microporous asphalt mortar to determine the linear viscoelastic graphene of micropaste mortar. The load determined is used to carry out fatigue test on the micro graphene capsule asphalt mortar after the load is completed intermittently. The fatigue testing is carried out again using the same test conditions. The loading is stopped when the dynamic modulus is reduced to a predetermined value. The test termination modulus terminal is recorded. The difference graphene between the fatigue curve before and after the interval is compared as a healing index. USE - Self-healing test evaluation method for graphene of micro-capsule asphalt mortar under double-mechanism function. Can also be used in graphene of graphene, graphene of carbon and graphene of aluminum. ADVANTAGE - The method accurately evaluates the self-healing effect of the micro graphene capsule asphalt mortar under the action of double mechanism, and has important meaning for the material design and engineering graphene of micro-capsule asphalt mortar. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the self-healing test evaluation method. (Drawing includes non-English language text).
