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,…
Infrasense, Inc. recently completed a subsurface pavement structure investigation of the Cleveland Memorial Shoreway using high-speed ground penetrating radar (GPR). The initial phase of the GPR evaluation included an analysis of the data to define the limits of the different structural “sections” of pavement throughout the length of both the outer eastbound and westbound shoulders.…
In 2012, Infrasense, Inc. completed a subsurface pavement thickness survey of 290 lane miles of the Parks Highway between Anchorage and Fairbanks, Alaska using ground penetrating radar (GPR). The thickness investigation employed the use of two different frequency antennas, designed to achieve the optimum tradeoff between resolution and depth of penetration. The objective of the…
Infrasense has performed a variety of different pavement projects across the state of Virginia, including statewide and citywide network-level evaluations and localized project-level evaluations for rehabilitation design
Infrasense worked with the Upper Great Plains Transportation Institute and Dynatest Consulting to complete a NDT subsurface pavement structure investigation as part of a legislature-commissioned study to determine the investment needs for all county and township roads and bridges in North Dakota. The pavement investigation project included GPR pavement thickness and structure data collection and…
In 2015, Infrasense carried out a pavement evaluation program for a ~2.8 mile section of Route 2 in East Hartford, Connecticut using a combination of ground penetrating radar (GPR), falling weight deflectometer (FWD), and selective coring. The objectives of this program were as follows: Confirm limits of full-depth asphalt and the composite sections of pavement…
Infrasense completed a subsurface pavement structure investigation of both directions of a 1-mile long viaduct on Interstate 93, just north of Boston. This viaduct, adjacent to the Leonard P. Zakim Bridge, leads directly into Boston, so minimal traffic disruption of this corridor is a priority. Infrasense used a high-speed ground penetrating radar (GPR) survey to detect…
Infrasense developed a roadway structure database to assist the Idaho Transportation Department (ITD) in its future project planning and design efforts and to ultimately advance the condition of the roadway to an acceptable level. The roadway structure database covers approximately 1000 miles of state highways within ITD’s District 6 and was generated primarily with data…
Infrasense just finished some fieldwork in beautiful Idaho, where plains, mountains, dark skies provided a refreshing change of scenery from our Boston office. Here’s a shot of our survey vehicle on a truss bridge (not a structure we were evaluating, just a great photo op!) with the MIlky Way stretching across the sky above us.…
Infrasense recently performed subsurface pavement structure investigations on 21 sections of pavement throughout Fort Hood. This project provided pavement structure information to support Falling Weight Deflectometer Testing (FWD) and subsequent rehabilitation planning and design.
