INVESTIGATION OF PAINTS AND GLASS BEADS USED IN TRAFFIC DELINEATION MARKINGS-PHASE 3

THE WHITE TRAFFIC DELINEATION PAINTS WHICH WERE INDICATED AS HAVING THE BEST WEAR RESISTANCE PROPERTIES FROM PHASE 1, COLD APPLIED PAINTS, AND PHASE 2, HOT APPLIED PAINTS, WERE USED TO TEST THE PROPERTIES OF VARIOUS TYPES AND CONCENTRATIONS OF REFLECTIVE GLASS BEADS IN PHASE 3. THE EVALUATION OF LONGITUDINAL CENTERLINE STRIPES WAS BASED ON DAYTIME AND NIGHTIME OBSERVATIONS AS DESCRIBED IN ASTM. THE RESULTS RECONFIRM THESE PAINTS AS BEING LONGER WEARING THAN THE MISSOURI DISPERSION RESIN-VARNISH PAINT. A TYPE II "FLOATING" BEAD WAS SHOWN TO RANK HIGH IN PERFORMANCE. AN ALTERNATE RATING SYSTEM FOR MEASURING THE NIGHT VISIBILITY OF EACH STRIPE WAS FOUND TO COMPARE VERY WELL WITH THE SUBJECTIVE RATING GIVEN IN THE ASTM METHOD. /FHWA/
