Microcapsules loaded with healing agent were successfully prepared in which 2,6-dimethylphenol(DMP) or SBS/DMP as healing agent form core, and urea/formaldehyde resin forms shell of the microcpasule. Microcapsule-contained asphalts showed better mechanical properties than non-contained ones. As time passed the impact strengths of microcapsule-contained asphalts was getting higher than that of its original. As the rest time of 3 and 7 days passed for microcapsule(SBS/DMP)-contained and microcapsule(DMP)-contained asphalt, respectively, their original strength was restored. This tells that microcapsule(DMP or SBS/DMP)-contained asphalts have the excellent self-healing ability. SEM and X-ray photos show that DMP on asphalt fracture surface, which burst out of the microcapsules when cracks occurred on surface of the asphalt, were polymerized to polyphenyleneoxide(PPO) and this PPO filled the crack and healed the damage.
