Sample Rebar Depth Map

Infrasense conducted a non-destructive survey and report of ten bridge decks along Interstate-190. The survey utilized Ground Penetrating Radar (GPR) to collect subsurface data, which in turn was used to produce maps of rebar depth and rebar level deterioration. The condition data provided to the client will help to prioritize rehabilitation efforts.

The surveys were conducted from a survey vehicle at traffic speed, implementing a 1 GHz horn antenna feeding into a SIR 30 radar acquisition unit, both manufactured by GSSI in Nashua, NH. No lane closures are necessary for this type of survey. The scan rate was regulated with a distance measurement instrument attached to the tire of the vehicle. Data was collected to provide 100% coverage, and then analyzed by Infrasesnse’s engineer specialists.
