SHRP2 R06D Research to Identify, Validate, and Implement Methods Capable of Detecting Pavement Delamination

Infrasense contributed to the original research efforts for the SHRP2 project titled, “Advanced Methods to Identify Pavement Delamination (R06D)”. The objective of this project was to identify and validate nondestructive testing technologies that can detect delamination in hot-mix asphalt (HMA), to operate at a reasonable travel speed, and cover a full lane width. Most recently,…

Pilot Project to Assess Capability of GPR for Detecting Void Space Between Decorative Fascia and MSE Walls

Infrasense completed a Pilot Study to establish a method for measuring the void space between a decorative fascia wall and a mechanically stabilized earthen (MSE) retaining wall using GPR. Ground-coupled GPR antennas were used to test the abutments of multiple bridges in Green Bay, where these MSE retaining walls are used in the design of…

Parking Garage Deck Condition Evaluation Using GPR in Portland, ME

Infrasense evaluated the condition of the upper parking deck of the Spring Street Garage in Portland, Maine. The evaluation utilized ground penetrating radar to quantify and map deterioration in the concrete slab, which was inaccessible for sounding due to an asphalt overlay. The GPR deterioration map was found to correlate reasonably well with areas of…
