ROAD MARKING MATERIALS 1ST INTERIM REPORT

TRAFFIC PAINT, THERMOPLASTIC AND RAISED MARKERS ARE DISCUSSED: MERITS AND SHORTCOMINGS NOTED IN EVALUATIONS ARE LISTED. RESULTS OF PAINT AND BEAD STUDIES WERE PUBLISHED IN A PREVIOUS REPORT; HOWEVER, THEY ARE INCLUDED FOR COMPARISONS. THERMOPLASTIC SECTIONS HAVE BEEN IN SERVICE FOR TEN YEARS IN THE STATE AND ALL BUT ONE ARE STILL IN SERVICE. RAISED CERAMIC AND REFLECTIVE MARKERS HAVE BEEN IN PLACE ON MISSISSIPPI ROADWAYS FOR LESS THAN TWO YEARS AND EXPERIENCE WITH THESE MARKERS IS LIMITED. NINETY-EIGHT PERCENT OF REFLECTIVE MARKERS AND NINETY-FOUR PERCENT OF CERAMIC MARKERS REMAIN IN PLACE AFTER ONE YEAR SERVICE. 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 THIRTY PERCENT ARE MISSING IN ONE-HALF MILE STRETCHES. COMBINATIONS OF PAINT, THERMOPLASTIC AND CERAMIC MARKERS ARE RECOMMENDED WITH RAISED REFLECTIVE MARKERS FOR LOW, MEDIUM AND HIGH VOLUME ROADS TO PROVIDE EFFECTIVE DELINEATION FOR ALL CONDITIONS EXCEPT SNOW. /FHWA/
