TRAFFIC MARKING MATERIALS EXPERIMENT

VARIOUS TRAFFIC AND BEAD COMBINATIONS WERE EVALUATED. THE PAINT AND BEAD COMBINATIONS WERE APPLIED TO PORTLAND CEMENT CONCRETE AND BITUMINOUS SURFACE AND WERE ALLOWED TO WEATHER APPROXIMATELY 1 YEAR. TWO TYPES OF WHITE TRAFFIC PAINT AND THREE TYPES OF REFLECTIVE GLASS SPHERES WERE USED. TWO RATES OF APPLICATION (4#/GA), AND 6#/GAL.) WEARE USED. THE CONCLUSION ARE AS FOLLOWS: (1) AN ADEQUATE FILM, 12 TO 15 MILS THICK, OF RUBBER BASE APPLIED TO A CLEAN, DRY SURFACE IS SUGGESTED; (2) A BEAD COMPARABLE TO #2 OF THIS REPORT AT THE RATE OF 4 LBS TO THE GALLON SHOULD BE USED AND (3) THE EFFECTIVENESS OF TRAFFIC STRIPE CANNOT BE ESTABLISHED DURING DAYLIGHT HOURS. AFTER 1 YEAR DETERIORATION AND THE STRIP HAD LOST APPROXIMATELY 50% OF ITS BEADS, IT WAS STILL A SERVICEABLE GUIDE IN MORNING FOG WHEN VISIBILITY WAS LIMITED TO 50 FEET. /FHWA/
