Abstract:

The objective of this project is to evaluate the current capability and the potential of the laser noncontact deflection and profile-measuring system Profilometer for use in the evaluation of airfield pavements. This study evaluates the use of lasers mounted on a 10-ft beam to measure pavement profiles and deflections near a loaded wheel. The lasers require no contact with the pavement surface. The algorithm for solution of the profile is presented along with the solutions for calibrating the system. The system is a promising tool for measuring surface roughness. Continued research is required to improve the system to provide the required accuracy.
