Abstract In order to improve the self-healing performacne of asphalt mortar, the asphalt regenerant was used as the core material. Isophorone diisocyanate (IPDI) and distilled water were used as the reaction monomers of the oil and water phases, respectively. Micro-scale damage self-healing microcapsule for asphalt regeneration agent coated with polyurea wall material was prepared by interfacial polymerization. The technical properties of microcapsules for road were evaluated from the aspects of microscopic morphology, particle size, wall thickness, chemical structure and thermal stability by scanning electron microscopy (SEM), infrared spectroscopy (FTIR), laser particle size analyzer and thermal gravimetric analyzer (TGA). Based on the beam bending healing test, the effects of microcapsule content, healing time, healing temperature and powder-binder ratio on the self-healing performance of micro encapsulated asphalt mortar were systematically studied. The results show that the prepared microcapsules for road have smooth and flat surface, uniform particle size distribution, intact capsule wall, stable chemical structure and good thermal stability. The self-healing performance of microencapsulated asphalt mortar firstly increases and then decreases with the increase of microcapsule content,firstly increases and then tends to be stable with the extension of healing time, firstly increases and then tends to be stable with the increase of healing temperature, and decreases with the increase of powder-binder ratio.
