Ground Penetrating Radar (GPR) Survey of Pavement Sections Located in Southwest Maryland

Infrasense completed a subsurface pavement structure investigation of 10 sections of shoulder pavement in Southwest Maryland using high-speed ground penetrating radar (GPR). The sections were surveyed in both driving directions to obtain continuous structure information for both bound and unbound material layers. The surveys were conducted below normal driving speeds in order to maintain a safe moving closure inside the shoulders, which are usually not as smooth as the lanes and contain debris and other obstructions. The GPR results will be used to supplement Falling Weight Deflectometer (FWD) back-calculations to achieve more accurate pavement properties, such as structural capacity and remaining life. The results of this project will be used for the design of upcoming rehabilitation work where traffic may need to be rerouted into shoulders.
