The invention discloses a silicon carbide microwave self-healing asphalt mixture as well as a preparation method and a self-healing method thereof, and aims to solve the problems of low microwave absorption efficiency and the like caused by poor wave absorption performance of aggregate in the existing microwave heating-based asphalt pavement self-healing technology. The silicon carbide microwave self-healing asphalt mixture is prepared from rock mineral aggregate and asphalt in parts by mass, wherein the rock mineral aggregate comprises the following components in parts by mass: 40-70 parts of basalt coarse aggregate, 0-50 parts of limestone fine aggregate, 1.6-4.2 parts of limestone mineral powder and silicon carbide powder, and the volume ratio of the limestone mineral powder to the silicon carbide powder is 7: 3-5: 5. According to the invention, the silicon carbide powder is adopted to replace limestone mineral powder in equal volume to fill the asphalt mixture, and the silicon carbide powder has excellent wave-absorbing performance, so that the microwave heating self-healing performance is improved, and the self-healing of the asphalt mixture is enhanced. And the silicon carbide powder wave-absorbing agent can be uniformly distributed in the mixture and is adhered to the asphalt, so that the uniformity of microwave heating is better.
碳化硅微波自愈合沥青混合料及其制备方法和自愈合方法,本发明为了解决现有基于微波加热沥青路面自愈合技术中由于集料的吸波性能较差,导致微波吸收效能低等问题。本发明碳化硅微波自愈合沥青混合料按照质量份数由岩石矿料和沥青组成;其中的岩石矿料以质量份数计,包括40~70份的玄武岩粗集料、0~50份的石灰岩细集料、1.6~4.2份的石灰岩矿粉和碳化硅粉,石灰岩矿粉与碳化硅粉的体积比在7:3~5:5之间。本发明采用碳化硅粉等体积替换石灰岩矿粉填充沥青混合料,碳化硅粉具有优异的吸波性能,使微波加热自愈合性能提升,增强沥青混合料的自愈合。碳化硅粉吸波剂在混合料中能均匀分布并与沥青胶粘,微波加热的均匀性更好。
