The invention relates to a repairing method for a concrete pavement. The repairing method comprises the following steps that damaged pits of the concrete pavement are cleaned up; high-pressure spray cleaning is performed; when no obvious water strain exists in the pits, a surface treating agent is sprayed on the broken concrete surface, wherein the surface treating agent is obtained by mixing phosphoric acid and hydrofluoric acid; after spraying is performed, standing is performed under an environment with the temperature of 15 DEG C-25 DEG C for 3-5 hours; drying is performed with a hot air blower; a bottom layer is painted on the broken concrete surface, a middle layer is sprayed on the surface of the bottom layer in 15 minutes after the bottom layer is painted, upper-layer concrete is poured on the middle layer in 30 minutes after the middle layer is sprayed, and surface-layer concrete is poured on the surface of the upper-layer concrete before initial setting of the upper-layer concrete; after room temperature standing and nursing are performed, repairing of the concrete pavement is completed. According to the repairing method, the defects that in the prior art, time consumption is long, and the repairing effect is poor are overcome.
