The objective of this project was to develop equipment to produce bridge surface profiles and make specification changes to control riding quality by use of these profiles. A 12-foot profilograph, a laser beam true profiler, and the 25-foot California Profilograph were tested and compared on a number of bridge decks. Use of the 12-foot profilograph was shown to be faster and more effective for evaluation of bridge deck smoothness than the 12-foot aluminum straightedge. Surface deviations were located with the profiling equipment that were not located or not capable of being located with the 12-foot aluminum straightedge. A proposed specification and test method are included in this report. /FHWA/
