EVALUATION OF TEMPORARY DAY-NIGHT VISIBLE RAISED PAVEMENT MARKER ADEQUACY

Compared to paint, day-night visible raised pavement markers improve construction-zone traffic performance significantly. However, there is a need to find temporary markers that can withstand construction-zone traffic. After initial screening, six marker types were tested further for visibility and durability. The features that met the criteria for an adequate day-night visible temporary marker installed with butyl on primer are a streamlined profile, a microscopic cube-corner, sealed prismatic air cell, cube-corner reflex, or multiple-glass lens reflector, and a balance between the reflector area and casing area exposed to the driver. Two marker systems met these requirements: (a) a hollow acrylic marker with a sealed prismatic air cell reflector such as the Stimsonite 66B by the Amerace Corporation; and (b) a combination of a domed-shaped polyester marker such as the Titan TM-40 by the Traffic Safety Supply Company for day visibility, and a filled ABS shell marker with a cube-corner reflex reflector such as the Ray-o-Lite by I.T.L. Industries, Inc., or equivalent for night visibility.
