Inlaid Pavement Marking Evaluation

Over the past three decades, MoDOT has tried multiple strategies to provide and improve wet nighttime guidance on its major routes, culminating in the current use of ASTM Type III glass beads on all lines on MoDOT’s major roadways. Before the implementation of the Type III bead system, MoDOT’s St. Louis District began experimenting with inlaid pavement markers (IPMs); however, to date, a complete evaluation of their effectiveness and life cycle cost has not been performed. Before moving forward with further implementation plans for IPMs, the performance and effectiveness of these devices needs to be determined in order to establish a statewide direction for the use of these devices. The objective of this study is to determine the benefits of IPMs on Missouri roadways considering our current wet reflective pavement marking system. It is believed IPMs will provide added benefit in certain locations; however, there is a question regarding the accuracy of national crash modification factors (CMFs) as they apply to Missouri’s roadways. It is assumed these CMFs were established based on IPM applications with standard pavement markings.
