High-inductivity self-healing asphalt concrete based on solid waste aggregate and preparation method of high-inductivity self-healing asphalt concrete
The invention relates to the technical field of intelligent maintenance of asphalt pavements, and provides high-inductivity self-healing asphalt concrete based on solid waste aggregate and a preparation method of the high-inductivity self-healing asphalt concrete. And the high-performance asphalt mixture which has good pavement performance and is rapidly heated under microwave/electromagnetic induction is prepared. The asphalt mixture has high inductivity and high thermal conductivity at the same time, temperature balance can be rapidly achieved while rapid heating is conducted, the molecular diffusion and capillary flow phenomena of asphalt are accelerated, self-healing of early diseases such as cracks and looseness of asphalt pavements is promoted, the durability of the pavements is improved, and therefore rapid and efficient maintenance of the asphalt pavements is achieved. The method can greatly save the maintenance time and the maintenance cost of the asphalt pavement, prolongs the major and medium maintenance time of the expressway, and has remarkable economic and social benefits.
本发明涉及沥青路面智能养护技术领域，提供基于固废集料的高诱导性自愈合沥青混凝土及制备方法，采用含金属矿物的矿渣替代普通集料，添加具有高诱导、吸波特性的纤维与填料，制备路用性能良好、在微波/电磁诱导下快速升温的高性能沥青混合料。该沥青混合料同时具备高诱导性和高导热性，在快速升温的同时可快速实现温度平衡，加快沥青的分子扩散与毛细流动现象，促进沥青路面裂缝、松散等早期病害的自愈合，提高路面的耐久性，从而实现沥青路面的快速高效养护。本发明可大幅节约沥青路面养护时间和养护费用，延长高速公路大中修时间，具有显著的经济和社会效益。
