PROBLEM TO BE SOLVED: To provide a road inspection device which is capable of improving safety of measurement work while improving the accuracy and reliability of measurement.SOLUTION: A road inspection device loaded on a road inspection vehicle 10 includes: a loaded device 30 which applies an impact to a road; flexure sensor devices which measure a degree of flexure of the road due to the impact from the loaded device 30; and a slide device 60 which moves the loaded device 30 to the right and left with respect to a travel direction of the road inspection vehicle 10 on the road. Two flexure sensor devices are installed so as to cope with the case where the loaded device 30 is located on the right and the case where it is located on the left. The road inspection device allows the impact to be applied to right and left portions of a traffic lane where ruts are formed, though the road inspection vehicle 10 is located in the central portion of the traffic lane without deviation. |
