| description | The invention belongs to the technical field of highway construction, and particularly relates to a self-healing pavement structure and a preparation method thereof, and the self-healing pavement structure comprises a microcapsule semi-rigid and semi-soft base layer, a second-order epoxy waterproof bonding layer and a low-dosage epoxy microcapsule OGFC-13 surface layer from bottom to top from the top surface of a cushion layer. The microcapsule semi-rigid and semi-flexible base layer is a semi-rigid and semi-flexible composite base layer formed by pouring emulsified asphalt doped with microcapsules into a framework gap type base layer with the void ratio of 15-23%, and the low-dosage epoxy microcapsule OGFC-13 pavement is a composite pavement formed by pouring permeable resin doped with microcapsules into low-dosage epoxy OGFC-13 with the void ratio of 18-25%. According to the self-healing pavement provided by the invention, when micro-cracks appear on the base layer and the surface layer, stress at the tips |
