Materials-Based Methods to Improve Rumble Strip Durability

The use of centerline rumble strips (CLRS) has been shown to reduce severe head-on crashes on two lane roads by up to 64%. The Federal Highway Administration (FHWA) has included rumble strips in their new “Proven Safety Countermeasures” initiative, which may result in more widespread use of rumble strips. Through the lens of pavement performance, installing CLRS in asphalt pavements may accelerate deterioration of the pavement at the longitudinal construction joint. Recent research has measured this effect and suggested chip sealing new rumble strips as a preventive measure; however, chip sealing following installation may not be practical or desirable for many reasons. Other materials that have a demonstrable impact on centerline joint durability, without sacrificing the functionality of the rumble strip, have been described, namely Void Reducing Asphalt Membrane (VRAM) and Rapid Penetrating Emulsion (RPE). This project will evaluate the efficacy of these material methods for improving CLRS durability while maintaining safety through the use of full-scale field projects.
