Abstract: A road surface management device 1 includes a deterioration detection unit 2, a deterioration index calculation unit 3, and a display processing unit 4. The deterioration detection unit 2 detects a crack in a road surface on the basis of an image of the road surface acquired from a vehicle. The deterioration index calculation unit 3 calculates, for the detected crack, a crack width and a crack rate on the basis of the image. The display processing unit 4 superimposes the calculated crack width and crack rate on the road surface on a map.
