Investigation of Retroreflective Pavement Markers (RPMs) in Rumble Strips

The use of snowplows in northern Texas frequently results in loss of retroreflective pavement markers (RPMs). The loss of RPMs is not only costly, but also creates unsafe driving conditions during inclement weather. Research Project 0-6995- Determine Use of Alternative Retroreflective Pavement Markers (RPMs) on Highways with Centerline Rumble Strips and Winter Weather Pavement Marking Improvements showed that rumble strips can be used in a multi-functional way to provide not only sound awareness, but also protect the retroreflective pavement markers from snowplows. The aims of this implementation project are to build upon the findings of Research Project 0-6995 and to (1) validate the visibility results of the RPMs in rumble strips from different distances and vehicle speeds and (2) confirm the long-term performance of the markers in rumble strips.
