A road surface evaluation apparatus includes a microprocessor configured to perform: acquiring driving information of each of vehicles, including a position and an acceleration of each of the vehicles while traveling, and a map information including road information on a road where the vehicles travel; evaluating a surface roughness of the road based on acquired accelerations of the vehicles; estimates a surface change location where the surface roughness has changed, based on a difference between a first road surface information including the evaluated surface roughness evaluated based on the acceleration of the vehicles acquired within a past predetermined period and a second road surface information including the evaluated surface roughness based on the acceleration of the vehicles acquired later than the past predetermined period; and outputting a road surface change information including the estimation result, in association with the road information.
