Infrasense Performs GPR Survey of Pavement Structure in Naugatuck, Connecticut

Infrasense conducted a nondestructive survey and report on the main travel lanes of a 1-mile section of Rubber Avenue in Naugatuck, CT. The project provided the client with tabular and graphical data sets plotted at a 5-ft interval along the centerline of each travel lane, with each point linked to precise GPS coordinates. These datasets…

Infrasense Performs GPR Analysis on 7000 Kilometers of Pavement in Israel

In Spring 2018, Infrasense founder Ken Maser traveled to northern Israel to train a local team on how to collect Ground Penetrating Radar (GPR) data for a network-level pavement survey. For the next seven months, the team collected 7000 km of pavement in 2240 management units. The data was continuously uploaded to Infrasense for quality…

Infrasense Scans Highway Pavement Outside Atlanta, GA

Last month Infrasense performed a high speed pavement survey on a stretch of Interstate highway outside the transportation hub of Atlanta, Georgia. The purpose of the project was to determine the structure for approximately 17 miles of pavement. Did you know that Georgia contains 15 different Interstate highways? That’s good for tenth most in the…

Infrasense Performs in Depth Nondestructive Evaluation of Pavement and Bridges Along I-95 in Southern Connecticut

This past summer, Infrasense surveyed 10 miles of interstate pavement and 23 bridge decks with ground penetrating radar. The objectives of the GPR survey included: Locating the lateral and longitudinal extents of the underlying PCC pavement and full-depth asphalt pavements Providing thicknesses of asphalt and PCC pavement layers Locating and quantifying deterioration in the underlying…

Pavement Structure Evaluations at Locations Throughout Maryland

InfrasenseĀ completed a subsurface pavement structure investigation of 18 sections of pavement in Western Maryland using high-speed ground penetrating radar (GPR). The sections were surveyed in both driving directions to obtain continuous structure information for both bound and unbound material layers. The GPR results will be used to supplement Falling Weight Deflectometer (FWD) back-calculations to achieve…

Infrasense Investigates Airport Pavement Structure using Ground Penetrating Radar (GPR) in San Francisco, California

Infrasense recently surveyed multiple runways, a taxiway, and a 240,000 square-foot apron at the San Francisco International Airport. The survey implemented a combination of 400 MHz and 1 GHz antennas mounted off the back of the survey vehicle. The use of both frequencies provided an excellent combination of data resolution and depth of penetration to…

Idaho I-86 Pavement District 5

Survey to Map Pavement Conditions for 22-Mile Section of I-86 in Southeast Idaho

This past summer, Infrasense conducted a multi-faceted non-destructive survey and report for 84 lane miles of a section of I-86, made up of abutted concrete panels. The project provided the client with a comprehensive set of condition results to identify and map out distressed panels along the roadway. Surveys were performed at normal driving speed…

Pavement Structure Evaluations for the Minnesota Department of Transportation (MNDOT)

Infrasense has performed pavement structure evaluations for the Minnesota Department of Transportation (MnDOT). Since 2015, ground penetrating radar (GPR) surveys totaling over 480 lane-miles were performed on roads in both the Metro and Northeast regions. For each project, preliminary GPR results were used to select cores to be used for calibration and confirmation of the…

High Resolution Imaging to Map Surface Distress for Section of Pavement in Wichita Kansas

A construction project near Wichita, Kansas involving the transportation of construction equipment and personnel between the state highway and a work site 3 miles down a two lane country road required a “baseline conditions” record to be produced. Infrasense was tasked with collecting high resolution video to both record and quantify the current road conditions,…
