Abstract: This paper presents ground-coupled ground penetrating radar (GPR) data-processing procedures for concrete bridge deck evaluation. GPR signals are analyzed in the depth range from the concrete surface to top reinforcement ...

Abstract: In this paper, air-coupled impact-echo is successfully applied for nondestructive evaluation of concrete. The air-coupled sensor is a small (

Abstract: The effect of steel reinforcement on the distribution of alkali-silica reaction (ASR) damage in concrete blocks is studied by leveraging acoustic emission sensing with a data-driven approach. The innovation lies in deriving ...
