▎ 摘　　要

NOVELTY - Material comprises 100 pts. wt. mineral aggregates, 5-6 pts. wt. asphalt, 2.5-5 pts. wt. self-healing microcapsules, and 0.5-2 pts. wt. thermally conductive phase change particles, where the shell layer of self-healing microcapsules includes sodium alginate cross-linked by calcium ions, and the interior of thermally conductive phase change particles includes a phase change agent, and the surface layer is grafted with high thermal conductivity graphene oxide. USE - The material is useful as pavement material for road (claimed). ADVANTAGE - The material: contains self-healing microcapsules, which releases repairing agent due to pressure at micro-crack, and repair micro-crack and makes self-healing; conatins heat-conducting surface layer, which conduct heat; has automatically decreased surface temperature; has intelligent effect of self-healing and self-cooling of road surface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing material.
