Infrasense performed high speed scanning on major highway bridges throughout Connecticut, including the Arrigoni Bridge in Middletown, the Sisson Avenue interchange on I-84 in West Hartford, and the complex “Waterbury Stacks” on I-84 in Waterbury. Combined, these projects represent over 1-million square feet of bridge deck. Infrasense collected ground penetrating radar (GPR) data on these bridge decks quickly and efficiently, without requiring lane closures or disrupting normal traffic flow.
The GPR data was used to produce deterioration maps and to locate cores for compressive strength testing and chloride sampling. The results of GPR scanning, core compressive strength testing, and chloride sampling provided a comprehensive condition assessment of each bridge deck, including deterioration quantities. These results were used to plan future rehabilitation efforts.
