Infrasense completed the subsurface pavement structure evaluation of approximately 79.93 lane-miles of public roadways in Falls Church, Virginia using Ground Penetrating Radar (GPR) testing to determine the thicknesses of the pavement structure layers. It was performed along the centerline of each roadway, centerline of each lane, and at an offset approximately 1 foot from the…
Infrasense’s Dr. Ken Maser presented the results of a network-level pavement substructure evaluation completed in Idaho. The project focused on a network of 700 miles of roadways covering a wide range of geographic and pavement structure conditions. The roadways were continuously surveyed with a Traffic Speed Deflectometer (TSD) and with Ground Penetrating Radar (GPR). The…
In mid-May, Infrasense began phase 1 of deck testing on 52 bridge decks throughout 12 counties in Oregon. We have started with the ground penetrating radar testing, and plan to return in July to perform infrared testing under more optimal weather conditions. Phase 2 will begin in late summer or early fall, after preliminary GPR…
Infrasense recently deployed an air-launched 3D-Radar system on projects in Iowa, Florida, and Virginia. The high-resolution system contains 21 antennas spaced 3 inches apart, and is capable of penetrating up to 5 feet below the surface. Infrasense has used this system to evaluate bridge deck, pavement, and tunnel deck conditions.
This past week, the Infrasense team spent a few days in the White Mountains to share some technical knowledge, explore the snowy outdoors, and prepare for what looks to be another busy year providing clients with accurate and useful NDE testing services. Activities ranged from an overview of our performance in 2016, a refresher…
