In early April, Infrasense conducted a non-destructive survey and report for 10 lane miles of a section of Route 2, in Rhode Island. The project provided the client with 4 sets of data showing where concrete appears to be present under the asphalt pavement versus an aggregate base. The survey was conducted at driving speed…
DetailsInfrasense and BDI recently teamed to perform a unique study of three bridges in Davie County, North Carolina for the North Carolina Department of Transportation (NCDOT). The objective of the study was to pilot a comprehensive NDE testing program on a small sample of bridge decks, which will be used as a basis for future…
DetailsIn May 2017, Infrasense carried out a GPR pavement thickness survey of 24 lane-miles of I-85 near Spartanburg, SC. The right shoulder, right lane, center lane, and left lane were surveyed in both northbound and southbound directions. The results of the survey included a statistical summary of the pavement layer thicknesses in each lane, as…
DetailsThis past summer, Infrasense conducted a multi-faceted non-destructive survey and report for 17 bridge decks in Wisconsin DOT’s North Central Region. The project provided the client with a comprehensive set of condition results to facilitate a data-driven approach to programming their bridge inventory. Surveys were performed at normal driving speed with no disruption to traffic.…
DetailsIn 2017, Infrasense welcomed Aleksey and Patrick aboard as our two newest full-time employees! Aleksey and Patrick will be filling Geoscience Engineer and Staff Engineer roles, respectively. Aleksey received his Ph.D degree in Geological Engineering from the Missouri University of Science and Technology (MS&T). During his postgraduate studies, he was actively involved in multiple projects…
DetailsInfrasense completed high-speed scanning of 19 bridge decks in 11 different counties throughout Virginia, totaling over 250,000 square feet. The scanning included Ground Penetrating Radar (GPR) evaluations. The deliverables included deterioration and rebar cover quantities and maps of the bridge decks. Per the request of the Virginia Department of Transportation (VDOT), individual deck condition reports…
DetailsInfrasense recently performed a ground penetrating radar (GPR) survey of the bridge deck carrying Lafayette Road over the Soo Line and B.N. Railroad in St. Paul, Minnesota. The GPR data collection system included dual 2GHz horn antennas and a SIR-30 control unit manufactured by GSSI of Nashua, NH. This GPR survey was carried out at…
DetailsInfrasense 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…
DetailsInfrasense’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…
DetailsIn 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…
