02 Aug Methods for Maintaining Pavement Marking Retroreflectivity
On August 5, 2022, the Federal Highway Administration (FHWA) published a final rule that incorporated a standard for maintaining minimum retroreflectivity levels for pavement markings into Section 3A.03 of the Manual on Uniform Traffic Control Devices (MUTCD) (see figure 1 and Appendix A). This document, referenced in the MUTCD, describes retroreflectivity maintenance methods that, when implemented as intended, provide agencies with a flexible means of conforming to the standard. This document includes a number of potential methods because different agencies have varying levels of staffing, equipment, budgets, road systems, and expertise.
