The invention relates to the field of road engineering, in particular to a snow-melting and defrosting type prefabricated conductive concrete overlay with crimp performance and a preparation method and application thereof. The snow-melting and defrosting type prefabricated conductive concrete overlay with the crimp performance comprises a polyurethane layer. Carbon fiber heating lines are distributed in the polyurethane layer. Gravel is distributed on the upper surface of the polyurethane layer. Aluminum foil is arranged on the lower surface of the polyurethane layer. The prefabricated conductive concrete overlay can serve as a temperature adjusting concrete thin-layer overlay, and the influence of ice and snow damage on the pavement structure and safety can be effectively eliminated.
