Outline of Final Research Achievements

In this study, for the purpose of quickly detecting the soundness lowering point of pavement due to the underlying cavity of the road surface generated in the sidewalk, etc., the mobile deflection measuring device using the turret truck was developed, and the demonstration experiment was carried out in the asphalt pavement section in the Tokyo University of Agriculture premises. As a result, it was confirmed that the soundness evaluation result by the mobile deflection measuring device was highly correlated with various test machines used for the under-road cavity exploration.

Academic Significance and Societal Importance of the Research Achievements

本研究で開発した移動式たわみ測定装置では,移動しながら連続的に非破壊検査を行うため,定点に非破壊試験機を設置して調査する既往の方法に比べて局所的な舗装の健全性の変化を精密に捉えることはできない。しかし,広域の調査を目的とする場合には,そのような局所的な変化を評価する必要はなく,舗装の健全性が低下しているエリアが把握できれば良い。そのような用途においては,本装置は効率よく舗装の非健全部を抽出できるものであり,今後の生活道や歩道といった歩行者系道路の維持管理の効率化に寄与できるものと考えられる。
