Intelligent pavement material and preparation method thereof
The invention relates to an intelligent pavement material and a preparation method thereof.The intelligent pavement material is prepared from, by mass, 100 parts of mineral aggregate, 5-6 parts of asphalt, 2.5-5 parts of self-healing microcapsules and 0.5-2 parts of heat-conducting phase-change particles; wherein a shell layer of the self-healing microcapsule comprises calcium ion cross-linked sodium alginate; the heat-conducting phase-change particles internally contain a phase-change agent, and the surface layers of the heat-conducting phase-change particles are grafted with high-heat-conductivity graphene oxide. According to the invention, the self-healing microcapsules and the heat-conducting phase-change particles are added into the asphalt mixture; the self-healing microcapsules can release the repairing agent at the micro-cracks due to the pressure effect, the repairing agent has the repairing effect, and the micro-cracks are repaired so that the micro-cracks can be self-healed; and in the heat-conducting phase-change particles, the heat-conducting surface layer can conduct heat, compared with an agent, heat is stored, the temperature of the surface layer is automatically reduced, and by adding the components, the pavement has the intelligent effects of self-healing and self-cooling.
本申请涉及一种智能路面材料及其制备方法，按照质量份数比，包括以下组分：矿物集料100份、沥青5~6份、自愈微胶囊2.5~5份、导热相变颗粒0.5~2份；其中：自愈微胶囊的壳层包括有钙离子交联的海藻酸钠；导热相变颗粒的内部包含有相变剂，表层接枝有高导热氧化石墨烯。本申请中通过在沥青混合料中加入了自愈微胶囊和导热相变颗粒；自愈微胶囊在微裂缝处会因为压力作用释放出修复剂，修复剂发生修复作用，修复微裂缝使其自愈；而导热相变颗粒中，导热表层会将热量进行传导，相比剂相比储热，使得表层温度自动降低，通过组分的添加，是路面具有自愈和自降温的智能效果。
