Pavement Thickness and Potential Voids Mapped in Iowa

InfrasenseĀ completed a subsurface pavement structure investigation of several miles of residential concrete pavement in LeClaire, Iowa. Using a vehicle-mounted GPR system, and ultrasonic Impact Echo and Impulse Response testing to supplement the GPR results, Infrasense mapped the thickness of the residential pavement and identified areas where potential voids could cause roadway settlement and damage. GPS data was collected synchronously with the GPR, so that results could be provided in a geospatial format
