Abstract:To further investigate the self-healing mechanism of microcapsules and exclude the interference of capsule-wall materials, a bi-plate test and a molecular model of asphalt and capsule-core materials were established using dynamic shear rheometer (DSR) and molecular dynamic (MD) simulation. Firstly, the models of asphalt-rejuvenator-asphalt and asphalt-epoxy resin-asphalt were established to simulate the interface of asphalt and capsule-core materials. The cross-linking between poxy resin and curing agent, and … Show more
