Durability of Reflective Pavement Markers and Development of Guidelines for Replacement

J. A. Wagner

In this study of the service life of pavement markers, it was found that markers deteriorate linearly with time and total traffic count after an initial rapid loss of intensity. The end useful life was shown to be the point at which the average intensity fell to 0.2 cp/ft-c for rural installations and 0.3 cp/ft-c for urban installations or when a certain critical number of markers became missing consecutively. Another finding of the study is that hot thermoplastic is superior to epoxy in bonding markers directly to thermoplastic stripes. The marker using a glass overlay on the face is shown superior to plain plastic markers.
