🌉 AASHTO / NCHRP (Bottom-of-Slab Reflection Attenuation dB, Delamination Mapping)

Bridge Deck GPR Deterioration Calculator

Map bridge deck concrete delamination and chloride-induced rebar corrosion using high-resolution ground-coupled GPR under AASHTO guidelines & NCHRP Report 560: calculate radar signal attenuation (dB drop caused by moisture and corrosive chloride ions), generate color-coded top-mat deterioration contour maps, and bridge rehabilitation engineering profits.
