TRAFFIC MARKING BEADS-ARE THE GRADATIONS RIGHT?

GLASS BEADS ARE APPLIED TO TRAFFIC MARKING PAINTS IN SUCH AN INDISCRIMINATE MANNER THAT SOME TIMES DETRACT FROM SAFETY, THE PURPOSE FOR WHICH GLASS BEADS ARE USED. GLASS- BEAD GRADATIONS NEED TO BE REVISED SO THAT THERE IS MORE RELATIONSHIP BETWEEN GRADATION SPECIFICATIONS AND APPLICATION REQUIREMENTS. A REVIEW IS PRESENTED OF ARTICLES PUBLISHED ON THE PROBLEM OF HOW GLASS BEADS ARE MADE AND USED IN TRAFFIC-MARKING MATERIALS. TECHNIQUES OF APPLICATION DEVELOPED FOR THE BEADS ARE: (1) PREMIXING BEADS WITH PAINT, AND (2) DROPPING THE BEADS ONTO THE PAINT AS IT IS BEING APPLIED. BENEFITS FROM THE USE OF IMPROVED BEAD GRADATIONS ARE DISCUSSED. BETTER GRADATION SHOULD PROVIDE MORE EFFECTIVE UTILIZATION IN SERVICE AND PRODUCE SAVINGS FROM THE PURCHASES OF LARGE QUANTITIES OF BEADS THAT NEVER FIND EFFECTIVE UTILIZATION.
