Road coring quality detection method

The invention relates to the technical field of detection devices, in particular to a road coring quality detection method, which comprises the following steps of: determining a road section to be subjected to coring according to requirements, acquiring an approximate area of first punching in a regional road section, accurately marking a first punching position, and performing first coring at a marking point; part of the punching position is marked and recorded on the end face of the sample core, so that metal in the sample core can be conveniently positioned in the later period; further, the sample core is detected, whether metal exists in the sample core or not is judged, if the metal exists in the sample core, the position of the metal in the sample core is obtained, the position of the metal in the sample core is compared with a mark recorded on the end face of the sample core and is compared with a part of marks on the ground, and the position of next punching is predicted; and the success probability o
