The non-destructive evaluation (NDE) of civil infrastructure has been an active area of
research in recent decades. The traditional inspection of civil infrastructure mostly relies on …

Delamanintions and reinforcement corrosion are two common problems in concrete bridge
decks. No single nondestructive testing method (NDT) is able to provide comprehensive …

In this large‐scale field study we use a prototype impact‐echo scanner to detect
delaminations on a concrete bridge deck surveying in total over 17,000 m2. Delaminated …

Cement-based repair materials are extensively used to rehabilitate damaged structures and
extend their service life. However, these materials experience bond deterioration and …

The objective of this work was to develop an automated air-coupled impact-echo testing
device for mapping the occurrence of delamination in a concrete bridge deck from a …

Abstract Evaluation of deteriorating highway bridges requires new, rapid inspection methods
to effectively guide repair in an era of limited fiscal resources. Of all the components of a …

The potential of concrete bridge delamination detection using infrared thermography (IRT)
has grown with technological advancements. However, most current studies require an …

Bridge damage detection has attracted much attention recently. Most studies on damage
detection of the high-speed railway (HSR) bridge neglect the effect of the interlayer …

In the field of non-destructive testing (NDT) for concrete structures, the traditional air-coupled
impact-echo technology often has the problems of complex operation and low efficiency. In …

In this study, an automated acoustic scanning system was developed for rapid delamination
detection on concrete bridge decks. A new ball-chain impact source was designed by …
