Pavement Structure Evaluation of 300 Miles of the Indiana Toll Road

Infrasense completed a subsurface pavement structure investigation of the Indiana Toll Road, which stretches 157 miles across the northern edge of the state and extends from the Illinois to the Ohio state lines. Using a high-speed vehicle-mounted GPR setup, Infrasense collected all the pavement data in one day with no road closures or disruption to normal traffic flow. GPS data was collected synchronously with the GPR, so that the results of the pavement structure investigation could be easily and accurately located in the field.
