Condition Evaluation of Concrete Bridge Decks with Asphalt Layer

레이더를 이용한 아스팔트 포장이 있는 콘크리트 교량 바닥판 상태평가

In this study, the usefulness of Radar method by means of assessing deck data-layer properties-was tested on the highway bridge. The obtained GPR data were compared with values measured from drilled cores and damage mapping by the visual survey. It is shown that GPR can provide the highly accurate measurements of layer properties of concrete decks and can map areas of deterioration in bridge by dielectric constants.
