Compliance and Best Practices for Pavement Markings

In August 2022, the Federal Highway Administration (FHWA) published a new rule in the Manual on Uniform Traffic Control Devices (MUTCD) establishing minimum retroreflectivity values for longitudinal pavement markings. Under the new rule, states have four years to develop a pavement marking maintenance method and six years to replace pavement markings that fail to meet the new minimum retroreflectivity values. Pavement markers are key components of pavement markings. Kentucky Transportation Cabinet (KYTC) is currently migrating to plastic inlaid markers (PIMs) from traditional snow-plowable raised pavement markers (SPRMs) on new and resurfaced roads. During this transition, KYTC and contractors are facing challenges related to durability, material availability, equipment needs, staffing/training needs, and the maintenance requirements required to prevent marker dislodgement. This project will identify roads subject to the new pavement marking requirements and investigate methods to assess compliance with new retroreflectivity minimums.
