New Nondestructive Pavement Evaluation Method

Abstract

Rapid nondestructive evaluation of pavements is needed to help maintain highways and airport runways. A review of current techniques for measuring pavement profile, texture, and deflection under load is conducted. Rapid evaluation of these parameters is needed, due to the high cost of closing highways and runways. The problem of improving the ability of pavement engineers to make these measurements is addressed first by reviewing existing procedures for obtaining these measurements, and then by presenting a new procedure to allow the pavement engineer to measure these three criteria. Currently there are no devices for the absolute measurement of pavement profile. The proposed procedure allows this absolute measurement to be made.
