• Abstract:
  Human vision is tuned to detect edges of contrasting color or brightness. Concrete pavements are so light in color that during the day and at night (especially during wet conditions), white pavement markings appear to blend in with the pavement surface. To improve the visibility of pavement markings on light-colored pavements, markings are applied over the top of a compatible black marking material. The underlying black stripe is applied at a greater width than the actual marking so that it provides a contrasting border around the marking, basically to give the driver an increased preview distance. This project will apply a white on black centerline boxed contrast epoxy stripe to portland cement concrete pavement (PCCP) within a diamond grind (recessed) groove. In addition; to add 3M Ceramic Elements and Visimax Plus striping beads to be blended with conventional Type 2 glass bead. The subject beads are claimed to provide increased retro-reflectivity and radiance during wet, nighttime conditions.
