Predicting Field Performance of Pavement Markings Statewide in Texas
Pavement markings and markers are the primary means for an agency to provide longitudinal guidance to drivers. To be effective, markings and markers must be visible during all driving conditions, day, and night. A variety of pavement marking materials (binders and beads) and varying installation specifications (application type, material thickness) create a wide range of initial performance and maintained performance over a markings service life. Currently, markings are evaluated initially to ensure a minimum initial retroreflectivity performance is obtained, but that initial performance has not been well researched to determine its impact on the overall durability and performance of the marking over its service life. The research team will explore various factors that affect pavement marking performance over the service life of the marking (pavement marking materials, installation specifications, pavement surface, traffic conditions, and geographic and climatic region) to develop performance models for Texas. Performance of a variety of markings and markers will be evaluated at various field test areas. These same marking materials will be evaluated through lab testing to explore accelerated weathering and wear tests that correlate with the field performance.
