PROBLEM TO BE SOLVED: To inspect a place of a crack and a degree of the crack even in the nighttime at which a road surface is dark by mounting a device having a vibration measurement instrument and a traveling speed measurement instrument on a vehicle, making the vehicle travel on a paved surface, and obtaining a measurement result by the device, to inexpensively manufacture an apparatus for use in the inspection, to dispense with the preparation of training data, to determine the inspection of the crack even if a traveling speed is changed, to easily install the vibration measurement instrument without worrying about an installation posture of the vibration measurement instrument, and to easily change the vibration measurement instrument and the vehicle for use.SOLUTION: In the paved-surface crack inspection method, a measurement device having a vibration measurement instrument, a traveling speed measurement instrument, and a vibration information correction instrument on a vehicle, the vehicle is made to travel on a paved surface being an inspection object, a measurement result by the measurement device is obtained, and a place of the crack and a degree of the crack are inspected even if the traveling speed is changed.SELECTED DRAWING: Figure 3
【課題】車両に、振動計測器と走行速度計測器を具備した装置を搭載し、検査対象の舗装面を走行し前記装置による計測結果を得ることで、道路面が暗い夜間においてもひび割れの場所とひび割れの程度を検査すること、検査に使用する機器を安価にできること、訓練データを用意する必要がないこと、走行速度が変わってもひび割れ検査の判定ができること、振動計測器の設置姿勢を気にせず簡便に設置できるようにすること、使用する振動計測器や車両の変更を容易にする。【解決手段】本発明の舗装面ひび割れ検査方法は、車両に、振動計測器と走行速度計測器と走行速度に応じ振動情報を補正する振動情報補正器を具備した計測装置を搭載し、検査対象の舗装面を走行し前記計測装置による計測結果を得て、走行速度が変動しても、ひび割れの場所とひび割れの程度を検査する。【選択図】図３
