Evaluation of the Performance of Rumble Strips on Pavements Where Seal Coats Have Been Applied

The repeated application of seal coats on pavements with rumble strips may reduce the effectiveness of the rumble strips to alert drivers of inadvertent lane departures. The goal of this project is to determine how many layers of seal coat can be applied on a pavement with rumble strips before rumble strip performance and, consequently, driver safety is compromised. The Proposing Agency will: 1) Review the literature for rumble strip performance thresholds for safety specifically relating to noise and vibration. 2) Develop a field-based testing plan using a statistical D-optimal design methodology. The plan will either be a before-after design of several projects scheduled for seal coat construction, or a repeated measures design of a few projects with controlled application and testing of multiple seal coat applications. Rumble strip location, seal coat grade, vehicle type, and speed are also considered. 3) Identify test sections according to the plan. 4) Measure interior noise and vibration for sections before and after seal coat application. Also measure texture with a laser profiler on select sections. 5) Determine how many seal coats result in an unacceptable drop in rumble strip performance.
