EVALUATION OF A NONCONTACT PROFILING SYSTEM USING THE ACOUSTIC PROBE

This article evaluates the Rapid Travel Profilometer and describes how the four States owning a profilometer make use of it. From the States' experiences, filter and gain requirements for a profiling system are established. A noncontact acoustic probe, its phase measuring equipment, an accelerometer, and commercial integrating and summing analog equipment that were mounted and installed in a sports van to determine road profile are discussed.
