The report covers a wide range of issues dealing with pavement markings. These include: reflectivity levels and visibility requirements, test deck evaluations, in-service testing, pre-mixed versus plain traffic paint performance, water base paints, and durable marking materials. Reflectivity levels and visibility requirements were analyzed using panels of untrained observers who were driven through predetermined sections of pavement markings at night and asked to rate the performance of those markings on a five point scale. These ratings were then compared to reflectivity readings taken on these same sections of pavement markings using a Mirolux 12 retroreflectometer. Test deck evaluations looked at the performance of both pavement marking tapes and traffic paints. A total of 13 tapes and 15 different traffic paints were installed. Evaluations included permanent and temporary removable tapes; pre-mixed versus plain paints, water base, and other durable traffic paints.
