The objectives of this phase of the overall "Roadway Delineation" study were to evaluate the luminosity and durability of several types of glass beads and one type of plastic bead used with paint stripes and to determine their effectiveness during rainy, nighttime conditions. Eleven types of beads were evaluated. They were applied at rates approximating 4, 5, and 6 pounds per gallon (479, 599, and 719 kg/m3). Photometer and visual observations extended to about 9 months after application of test stripes.
