EVALUATION OF RAISED PAVEMENT MARKERS

FOUR REPRESENTATIVE TYPES OF MARKERS WERE CHOSEN FOR STUDY. THESE WERE INSTALLED ON HEAVILY TRAVELED ROADS IN BATON ROUGE, LA. TRAFFIC WEAR AND BREAKDOWN PROPERTIES OF THESE MARKERS WERE CAREFULLY OBSERVED AS WAS THE EFFECTIVENESS OF VARIOUS LAYOUT PATTERNS ON THE ROADWAY. LABORATORY ATTEMPTS WERE MADE TO DUPLICATE THE WEAR AND ABUSE OBSERVED ON THE ROADWAY INSTALLATIONS. IT WAS DETERMINED THAT SUPPLEMENTING PAINTED LINES WITH RAISED MARKERS AT 40-FOOT CENTERS IS VERY EFFECTIVE AND PRACTICAL. A REFLECTIVITY MEASUREMENT SYSTEM WAS DEVELOPED AS A RESULT OF THIS STUDY AND THIS IS NOW A ROUTINE TEST IN THE DEPARTMENT. THE SIX DIFFERENT TYPES OF EPOXIES STUDIED FOR BONDING MARKERS TO THE ROADWAY ALL GAVE SATISFACTORY PERFORMANCE WITH ALL MARKER TYPES TESTED. HOWEVER, ONLY TWO MARKERS, THE STIMSONITE AND RAY-O-LIGHT, STAND UP WELL UNDER TRAFFIC AND PROVIDE ADEQUATE REFLECTIVITY RETENTION. /AUTHOR/
