Abstract
The speed of vertical electrical impedance testing of a concrete bridge deck using a new rolling probe was demonstrated in this research to be 190â¯m2/h, which is more than six times faster than the speed at which data were collected using the static probe utilized in earlier research. Furthermore, with impedance measurements obtained at a longitudinal spacing of approximately 0.1â¯m, the spatial resolution was 12 times greater than that of the static probe. Vertical electrical impedance testing was performed together with half-cell potential testing, chaining, cover depth, and chloride concentration testing, and an interpretation of these data sets was developed that synergistically incorporated the deck maintenance history.
