“Through the course of conducting my duties for the Asphalt Institute, I have increasingly noticed the use of centerline rumble strips when traveling. I could not help but wonder what, if any, negative effect they might be having on pavement deterioration. My concern stemmed from the fact that the final longitudinal joint on many rural two-wayroadways is at their centerline. So, milling a rumble strip into what is also commonly the most problematic location of a pavement raised concerns for me. That quickly evolved into a desire to make information available on the best ways to install and maintain all rumble strips, especially at the centerline.”
