Air Force Research Laboratory on Autonomous and Non-Destructive Pavement Surface Assessment Postprint

Abstract

Current techniques used to evaluate airfields, include falling weight deflectomers, dynamic cone penetrometers and core sampling; these methods are slow, laborious, and destructive to the pavement being sampled. The LUNS system uses a non-contact system which uses a high intensity laser to pulse pavement samples. These samples respond by reflecting off a compression wave. The compression wave can be analyzed to determine the depth of the concrete and various other concrete properties. This system, while still at the bench level, could eventually be used to evaluate the overall quality of runways non-destructively, while expediting the process from its current level.
