Bridge Deck Scanning

Advanced Assessment for Safer Infrastructure

Overview

Infrasense utilizes a broad suite of established nondestructive evaluation (NDE) methods including Ground Penetrating Radar (GPR), Infrared Thermography (IR), Aerial Infrared Thermography, and Rapid Automated Sounding (RAS) to assess bridge deck conditions. The NDE data is referenced to the bridge deck surface using both a survey grid and high-precision, differential GPS coordinates to accurately identify and locate areas of concern.

By quantifying and mapping the areas of concern, the appropriate maintenance, preservation, and rehabilitation strategies can be identified for each bridge deck. In cases where rehabilitation is needed, the scope and work requirement for repairs can be accurately estimated prior to performing the work. This allows repair budgets to be used efficiently by focusing available funds on the bridge decks most in need of repair. Accurately  identifying compromised areas and percentage of the bridge for repair helps bridge owners avoid costly overruns.

The GPR and IR data is collected according to ASTM 6087 and ASTM 4788, using state-of-the-art technology.

Capabilities

Detecting and quantifying bridge deck delamination, spalling, and patching.
Identifying corrosion-induced concrete deterioration
Measuring thickness of asphalt overlays and concrete cover
Assessing overall structural integrity at highway speeds

Results You Can Trust

In addition to comprehensive condition assessment, the processed NDT data can provide the following:

  • Comprehensive NDE Inspection Reports
    Concrete conditions quantified and mapped with deterioration analysis and repair recommendations.
  • GIS & CADD Compatible Condition Maps
    Plan-view maps showing deterioration, delamination, cracking, spalling, and patching by span or lane.
  • Geospatially Referenced Results
    Allowing integration into ArcGIS with high-resolution plan-view images of the entire deck surface.

Technology & Tools

Ground Penetrating Radar

GPR detects compromised concrete and subsurface delaminations and measures concrete cover by analyzing electromagnetic pulse reflections from rebar and structural anomalies.

Infrared Thermography & Aerial IR

Infrared thermography identifies temperature variations indicating delaminated areas, moisture intrusion, and thermal anomalies in bridge decks. Aerial thermal imaging provides comprehensive deck assessment on hundreds of decks per day.

Rapid Automated Sounding

Automated acoustic scanning detects hollow sounds and delaminations through chain-wrapped wheels that impact the deck while driving at rolling speeds.

“We’ve partnered with Infrasense on a range of projects over the years, and they’ve consistently delivered. Their team brings deep technical expertise, professionalism, and a willingness to go the extra mile—especially on fast-moving or complex jobs where precision matters most. When we need GPR or specialized NDE, Adam is always our first call.”
— Mollie Rhett, Director of Marketing, ICC-IMS
“NCE has partnered with Infrasense on local and state highway pavement evaluation projects for more than 15 years. Infrasense provides extensive knowledge and expertise with GPR testing and analysis, providing valuable layer thickness information for assessing and selecting pavement rehabilitation treatments. Due to Adam and his team, Infrasense is the only GPR specialty firm we call.”
— Linda Pierce, Principal, Nichols Consulting Engineers
“For a complicated project in Harvard Square, Kleinfelder hired Infrasense to conduct GPR of the roadway, redline tunnel and the utilities using Infrasense’s technology. The data was proven to be valuable to determine the existence of utilities in question where records were not complete, the roadway structure, and the MBTA redline tunnel where we were not able to get a permit to excavate to locate the top of the tunnel due to permitting issues. The data and technology has come a long way and was proven to be invaluable.”
— Tyson Ross, Senior Project Professional, Kleinfelder

Have a Question?

  • We typically deploy Ground Penetrating Radar, Infrared Thermography, and Rapid Automated Sounding together to detect different types of deterioration—GPR identifies corrosion and subsurface damage, IR reveals delaminations and moisture intrusion, while RAS provides acoustic verification of debonding. This multi-method approach ensures no defects are missed and provides the complete condition picture needed for accurate rehabilitation planning.

  • Our vehicle-mounted systems collect complete deck condition data at highway speeds, typically completing assessments in hours rather than the days or weeks required for manual inspection methods. The high-speed data collection eliminates lane closures and traffic control costs while providing more comprehensive coverage than traditional techniques can achieve.

  • We deliver comprehensive NDE inspection reports with quantified deterioration mapping, GIS-compatible condition data, and detailed analysis that meets ASTM 6087 and ASTM 4788 standards. Our GPS-referenced results integrate seamlessly into bridge management systems and provide the defensible condition assessment documentation required for federal reporting and rehabilitation funding applications.
