A nondestructive inspection of 52 bridge decks was conducted in central New York State utilizing Ground Penetrating Radar (GPR). The objectives of the GPR inspection were to provide an up‐to‐date assessment of the physical condition of the concrete deck, including the overall quantity of deteriorated concrete within the bridge and on a span by span ?page_id= Maser, K. “Integration of Ground Penetrating Radar and Infrared Thermography for Bridge Deck Condition Assessment.” Proceedings of the 7th International Symposium on Non-Destructive Testing in Civil Engineering (): Nantes, France.

Faced with a severely reduced budget, bridge engi neers now more than ever need reliable data from routine deck-condition surveys to aid them in the assignment of priorities and scheduling of mainte nance on bridge Biography.

This paper summarizes the theoretical and practical aspects of the application of radar and thermography to bridge deck condition surveys. A prototype vehicle was developed.
The radar waveforms and the thermographic images were calibrated in the field to various forms of physical :// Infrared thermography will measure the temperature of the surface of the concrete; and delaminated areas should show up as areas of different temperature compared with the bridge deck as a whole.
This technique can be carried out from a distance from the underside of the bridge deck, e.g. from the hard shoulder in the case of a motorway.

“You can actually scan a bridge deck without coring or testing,” says Evan Guarino, Field Engineer for INFRASENSE Inc., a GPR consulting firm in Arlington, Massachusetts. “We find GPR to be better than coring or infrared thermography. It’s the fastest and most efficient option to get an accurate condition of the bridge deck.” and Nehdi, M.

The GPR test was performed on bridge deck covering an area around 7 m × 60 m approximately. Over the bridge deck, a total of 54 longitudinal and transversal array scans were cautiously collected. Results of data processing •Delamination surveys cannot be conducted on decks with AC overlays at higher ambient temperatures.
•When there is debonding between the overlay and deck, no information about the deck condition can be provided. •Rebar and duct detection, and duct grouting condition evaluation, limited to The field application of three different nondestructive tests (NDTs)—air-coupled impact echo (IE), infrared (IR) thermography, and sounding (chain drag)—are evaluated in this paper, where an actual in-service concrete bridge deck is ://(ASCE)EM InInfrasense welcomed Aleksey and Patrick aboard as our two newest full-time employees.
Aleksey and Patrick will be filling Geoscience Engineer and Staff Engineer roles, respectively. Aleksey received his Ph.D degree in Geological Engineering from the Missouri University of Science and Technology (MS&T).
During his postgraduate studies, he was actively involved in multiple projects. Traditional infrared thermography surveys of bridge decks have been carried out at low speed (10 mph).In recent years the cameras have improved, and this, along with the DOT’s push to eliminate closures, has encouraged agencies to solicit, and providers to conduct, highway speed infrared :// Unfortunately, this book can't be printed from the OpenBook.
