Rumble Strip Installation

The objective of this project is to prepare a synthesis of best practices from various state transportation agencies (STAs) and other transportation stakeholders regarding the installation and re-installation of rumble strips on pavement treated with a thin pavement overlay. These include three rumble strip types (centerline, edge line, and shoulder), two standard rumble strip depths (3/8" and 1/2"), and three thin overlay types (hot mix asphalt, microsurfacing, and seal coat). These best practices will provide a standardized, cost-effective process for the Pennsylvania Department of Transportation (PennDOT) to effectively utilize rumble strips in conjunction with thin pavement overlays while considering existing rumble strips.
