Abstract:The use of snowplows in northern Texas frequently results in the loss of retroreflective raised pavement markers (RPMs). The loss of RPMs is not only costly but also creates unsafe driving conditions during inclement weather. Pavement sections in many regions across the state of Texas often use a centerline rumble strip for safety. Traditionally, these rumble strips have precluded the use of metal-encased RPMs (i.e., snowplowable RPMs). This paper is focused on determining the efficacy of inserting commerciall… Show more
