PROBLEM TO BE SOLVED: To mount on a general purpose vehicle a general purpose device equipped with a vertically moving detector, allowing the presence or absence of a defect to be inspected by travelling on the travel road of an inspection object, to reduce an economic burden of possessing the inspection device by utilizing the general purpose vehicle and the general purpose device with the time required for the inspection reduced, and to increase the inspection frequency by allowing the number of possessed inspection devices to be increased, and also to allow the inspection to be made whether the defect exists not only on the road, but also on bridges and the high level roads.SOLUTION: The method for inspecting the presence or absence of a travel road defect uses two kinds or more of vehicles having different weights, and mounts a vertically moving detector on the vehicles. Thereby, a measurement result of travelling on the travel road of an inspection object is obtained to find a difference caused by the weights of the measurement result, and places having a large difference are extracted as places in which a defect exists. |
