• Abstract:
  This report was prepared to provide the results of evaluations conducted upon twenty-six roadways where rumble strips were installed experimentally in Louisiana between August 1982 and September 1984. Situated randomly throughout Louisiana, construction of these coarse-textured, exposed sandstone aggregate rumble strips was accomplished by district maintenance forces using conventional asphalt distributing equipment. ; The purpose of this project was to develop a supplement to typical traffic control devices, such as signs or signalization, where a substantial reduction in speed is required to divert driver inattentiveness towards a potentially hazardous intersection or situation. It was hoped that the audible and tactile stimuli provided by the designated intermittent pattern of the coarse-textured, exposed sandstone aggregate rumble strips would increase driver reaction time, thereby creating the reduction in speed necessary to reinforce or augment standard visual traffic control devices. ; This report addresses installation techniques/problems, relative aggregate durability, aggregate loss determinations, possible rejuvenation procedures and analyzes historical accident statistics prior to and after installation.
