• Abstract:
  Empirical evidence shows that raised pavement markers are an ongoing maintenance challenge. Furthermore, a dislodged RPM opens an ingress point for water to reach the sub pavement, potentially reducing the design life of the pavement. To address this issue, Indiana conducted an evaluation of centerline rumble stripes (CLRSs) as an alternative to RPMs on rural, non‐interstate, roadways. Five pilot test sites consisting of 41.2 miles of roadway were constructed to evaluate CLRS performance in multiple regions of Indiana under various pavement conditions. CLRS were subsequently incorporated into INDOT’s 2013 Goals and approximately 238 project miles were programmed for construction. The project team participated in the development of a new specification for use in contract lettings after September 1, 2013. This technical report summarizes that evaluation, briefly summarizes the project background and development of CLRS specifications, provides detailed photos of a Fall 2013 deployment, and summarizes the post—construction close out meeting held on December 4, 2013.
