<p>PROBLEM TO BE SOLVED: To provide a road surface inspection device that can perform a road surface measurement without trouble at a central area of a road lane as well as at a position off from the road lane center such as a wheel track.SOLUTION: A road surface inspection device comprises a measurement hole provided on a floor part of a vehicle, an impact load applying mechanism 40 for applying an impact load on a road surface through the measurement hole, a load cell 50 for measuring the impact load, a deflection measurement sensor 51 for detecting a deflection of the road surface due to the impact load, and a width-direction drive mechanism for moving the impact load applying mechanism 40 in the width direction of the floor part. The width-direction drive mechanism can change a width-direction position of the impact load applying mechanism 40 on the vehicle floor part.</p> |
