Infrasense was in Wayland and Framingham, Massachusetts last week to perform a nondestructive bridge deck condition survey. GPR data was collected using a survey vehicle at normal driving speeds, eliminating the need for lane closures.
Infrasense was in Warwick, Rhode Island to collect GPR data on an elevated bridge at T.F. Green Airport.
Infrasense was recently in Southport, New York to perform nondestructive testing of a bridge deck using ground penetrating radar and high resolution imaging .
Infrasense scanning the underside of a bridge in Providence, Rhode Island this week! The testing consisted of high-frequency ground coupled surveys of concrete box girders, so we needed a lift truck to gain access to the underside surface.
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.
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…
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…
This past summer, Infrasense surveyed a bridge deck in La Crosse, Wisconsin using infrared for deck delamination detection according to ASTM D 4788 – 03. The equipment setup involved a dedicated vehicle mounted with a high resolution, distance triggered FLIR infrared camera synced up with a high-resolution visual spectrum camera. Both devices capture a whole…
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…
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…
