Bridge Deck Survey in Cleveland, Ohio
Infrasense was in Cleveland, Ohio last week to perform a ground penetrating radar (GPR) survey of a relatively new bridge deck in order to map the concrete cover.
Bridge Deck Testing in North Brookfield, Massachusetts
Our team recently completed testing on a bridge in North Brookfield, MA to provide as-built information including rebar spacing, rebar diameter, and concrete compressive strength in support of a load rating. In order to collect data on the culvert underside, Infrasense engineers used wetsuits and a small raft to keep themselves and the testing equipment dry…
Pavement Evaluation of I-17 in Arizona
Infrasense was in Arizona last month testing a section of highway between Phoenix and Flagstaff using various frequencies of ground penetrating radar (GPR) and high resolution video (HRV). The objective of the project was to characterize the pavement structure, evaluate the condition of the bound materials and joints, and provide surface imagery for limited sections…
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
Infrasense 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 Evaluates Condition of Stone Arch Bridge in Orange, Connecticut With Ground Penetrating Radar
In July of 2018, Infrasense mobilized a two-man team to perform a ground-coupled GPR survey of the road surface on a stone arch bridge in Orange, CT. With the help of a traffic control unit and a local police officer, the condition survey was carried out during overnight hours with minimal disruption to traffic. The…
Infrasense Evaluates the Condition of 5 Missouri Bridge Decks Utilizing Ground Penetrating Radar (GPR) Supplemented with Other Methods
This past summer, Infrasense conducted non-destructive surveys and reported for 5 bridge decks in Missouri. The project provided the client with a comprehensive set of condition results to facilitate a data-driven approach to programming rehab and maintenance efforts. As a supplement to the GPR surveys, chain drag, coring, and infrared thermography were used on select bridge…
