Although raised pavement markers (RPMs) have been widely applied by the Indiana Department of Transportation (INDOT), there have been multiple cases where snowplowing activities have damaged pavements as well as the raised pavement markers on INDOT’s roadway assets. Dislodged raised pavement markers could reduce the design life of pavements because they leave openings for water and debris to infiltrate through pavement section. Interviews with INDOT personnel indicated that the proper installation of the markers and careful attention to the tooling of the center line of the concrete pavements could alleviate this problem. To explore issues related to the proper installation of RPMs, this study (INDOT/JTRP SPR 4318) was launched by the Indiana Department of Transportation (INDOT)/Joint Transportation Program (JTRP) to develop a synthesis of current practices on installation and maintenance of raised pavement markers at State Transportation Agencies (STAs) in the U.S. The study was conducted using a qualitative exploratory approach focusing on the review of current practices in installation and maintenance of raised pavement markers among STAs. Survey analysis and focused interviews with personnel from STAs, along with reviews of documents provided by STAs were the avenues used for data collection in this project.
