Description: Technical Report
Abstract: The ERDC was tasked by the U.S. Air Force to evaluate emerging nondestructive thickness measuring devices to determine their ability to accurately estimate the pavement surface thickness without requiring large footprint equipment or repairs. Companies with products using non-destructive technology were down-selected to participate in a study requiring them to estimate the thickness of 40 asphalt and concrete locations with nondestructive devices. For each of the different pavement types, a single core was extracted to provide vendors with calibration points. Vendors provided initial thickness estimates, and upon receiving the calibration core thicknesses, vendors provided final thickness estimates. The results were compared to determine the accuracy and feasibility of the devices tested.
