Idaho Bridge Deck Condition Evaluations as Part of Network Level Survey

As part of the roadway structure database Infrasense developed to assist the Idaho Transportation Department (ITD), we also collected and analyzed data to assess the condition of each bridge deck located on the pavement network. Infrasense used high-speed Ground Penetrating Radar (GPR), Infrared Thermography (IR), and High-Resolution Video (HRV) testing to create plan view maps…

Infrasense at Northeastern Universiry

NIST-Sponsored research project to develop vehicle based system system for automatically detecting pavement conditions

Infrasense supported the research team at Northeastern University in developing a survey vehicle system to automatically detect and process surface and subsurface roadway defects. The project, entitled VOTERS (Versatile Onboard Traffic Embedded Roaming Sensors), is part of NIST’s Technology Innovation Program, and focuses on the subsurface sensing of pavements and bridge decks. Some of the…

SHRP2 R06D Research to Identify, Validate, and Implement Methods Capable of Detecting Pavement Delamination

Infrasense contributed to the original research efforts for the SHRP2 project titled, “Advanced Methods to Identify Pavement Delamination (R06D)”. The objective of this project was to identify and validate nondestructive testing technologies that can detect delamination in hot-mix asphalt (HMA), to operate at a reasonable travel speed, and cover a full lane width. Most recently,…

Aerial Infrared Thermography

PILOT PROJECT: Aerial Infrared Thermography Used to Evaluate Wisconsin Bridge Decks

Infrared thermography is one of our primary testing technologies for Wisconsin bridge deck condition evaluations, and we are always seeking ways to improve our testing methods. In 2017, this research really took flight – literally! Infrasense has also been working with a national aerial imaging company to collect and analyze infrared and visual imagery from…

GPR used to map concrete deterioration and rebar depth and spacing in multiple new york parking structures

GPR Used to Map Concrete Deterioration and Rebar Depth and Spacing Multiple New York Parking Structures

Infrasense has provided nondestructive evaluation services to multiple parking structures in New York, including the Crowne Plaza Syracuse parking garage, the NY East End parking garage, and the NY Civic Center parking garage. At the Crowne Plaza garage, Infrasense carried out GPR testing to map the location and depth of steel reinforcing bars within a…

Infrasense Tech GPR survey of tunnel wall in Virginia

NDE Scanning and Mapping of Hampton Roads Tunnel Conditions

The Virginia Department of Transportation commissioned Infrasense to perform condition evaluations of the walls and roadway deck of the Hampton Roads Tunnels, which carry I-64 below the Chesapeake Bay in Norfolk, Virginia. The eastbound and westbound tunnels are 7,315 feet and 7,470 feet in length, respectively. The tunnel wall evaluations were carried out using a…
