PROBLEM TO BE SOLVED: To provide a pavement crack analyzer, a pavement crack analysis method and a pavement crack analysis program allowing for reduction of labor required for calculation of a cracking ratio.SOLUTION: The pavement crack analyzer of an embodiment includes a pavement crack detection part and a cracking ratio calculation part. The crack detection part automatically detects a crack on a road surface on the basis of a taken image obtained by photographing the road surface. The cracking ratio calculation part sets a frame with a predetermined area between starting and terminal points set on the basis of the taken image, and calculates a cracking ratio indicating a ratio of an occupied crack area in the predetermined area, on the basis of the set frame and the crack.SELECTED DRAWING: Figure 1
