Defining the Deterioration Process Through Ground Penetrating Radar

The work described in this paper seeks to further the understanding between ground penetrating radar (GPR) measurements and the different stages of bridge deck deterioration. This goal has been accomplished by evaluating slabs cast in a controlled environment and sections of in-service bridge decks. Seventeen fabricated slabs, previously exposed to an accelerated corrosion process over an extended period of time, were evaluated using half-cell potential (HCP) and GPR measurement methods. Another slab subjected to a similar accelerated corrosion process was tested continuously over a period of nine months. Both experiments in which slabs were subjected to accelerated corrosion indicate correlations between average half-cell potentials and GPR rebar reflection amplitudes. The 17 laboratory slabs show a correlation between HCP and GPR at a single point in time, while the continuously tested slab shows this correlation throughout the deterioration process.
