REFLECTIVE TRAFFIC BEAD STUDY. FINAL REPORT

EVALUATION OF A NEW FLOATING TYPE OF TRAFFIC BEAD BY THE COLORADO DIVISION OF HIGHWAYS SHOWS THAT THESE SMALL UNIFORMLY-GRADED BEADS ARE SUPERIOR IN BOTH BRIGHTNESS AND DURABILITY TO THE COARSER TRAFFIC BEADS THAT THE STATE HAD BEEN USING. THE TESTS WERE PERFORMED ON CENTERLINE STRIPES PLACED ON BOTH ASPHALT AND CONCRETE SURFACES. DURING THE THREE YEAR TEST PERIOD, THE BRIGHTNESS OF 78 TEST SECTIONS WAS EVALUATED BY HUMAN EVALUATION TEAMS AND BY A PHOTOMETER DEVELOPED DURING THE PROJECT. PLANS FOR THE CONSTRUCTION OF THESE PHOTOMETERS ARE INCLUDED IN THE REPORT AS AN AID TO OTHERS WHO MAY WANT TO EVALUATE BEAD PERFORMANCE. /HSL/
