ROAD MARKING MATERIALS. 2ND INTERIM REPORT

THIS REPORT OF ROAD MARKING MATERIALS IS AN INTERIM REPORT ON A TYPE B STATE STUDY. TRAFFIC PAINT, THERMOPLASTIC AND RAISED MARKERS ARE DISCUSSED AND MERITS AND SHORTCOMINGS NOTED IN EVALUATIONS ARE LISTED. RESULTS OF PAINT AND BEAD STUDIES WERE PUBLISHED IN A PREVIOUS REPORT FOR THIS STUDY BUT ARE INCLUDED FOR COMPARISONS. THERMOPLASTIC SECTIONS HAVE BEEN IN SERVICE FOR ELEVEN YEARS IN THE STATE AND ALL BUT TWO SECTIONS ARE STILL IN SERVICE. RESULTS SHOW THE STATE CAN PLAN ON TEN YEARS SERVICE FOR THERMOPLASTIC INSTALLATIONS. RAISED CERAMIC AND REFLECTIVE MARKERS HAVE BEEN IN PLACE ON MISSISSIPPI ROADWAYS FOR OVER THREE YEARS AND EXPERIENCE WITH THESE MARKERS IS LIMITED. ESTIMATED ANNUAL LOSS RATE IS 2-5% OF REFLECTIVE MARKERS AND 5-10% OF CERAMIC MARKERS. MANY OF THESE MARKERS FAILED BECAUSE OF POOR BOND. TRAFFIC IS DETRIMENTAL TO CERAMIC MARKERS IN CURVES AND IN AREAS WITH MUCH LANE CROSSING. REPLACEMENT OF CERAMIC MARKERS IS NECESSARY IN SEVERAL LOCATIONS WHERE UP TO FIFTY PERCENT ARE MISSING IN ONE-HALF MILE STRETCHES. RAISED REFLECTIVE MARKERS ARE RECOMMENDED TO SUPPLEMENT PAINT OR THERMOPLASTIC STRIPES TO PROVIDE LANE DELINEATION DURING INCLEMENT WEATHER. REFLECTIVE MARKERS MUST BE USED WITH CERAMIC MARKERS TO PROVIDE NIGHT TIME DELINEATION. /FHWA/
