GLASS BEADS IN PAINT

SEVERAL ITEMS OF LABORATORY EQUIPMENT WERE USED TO STUDY GLASS BEADS IN PAINT. WEAR AND ABRASION OF BEADS AND PAINT WERE STUDIED WITH A TYPE OF SURFACE ABRASION EQUIPMENT DEVELOPED BY CALIFORNIA. TEXTURE OF ROAD SURFACES WAS MEASURED BY THE USE OF CORES AND LINEAR TRAVERSE EQUIPMENT. BINOCULAR AND PETROGRAPHIC MICROSCOPES WERE USED TO STUDY PAINT AND BEAD PROBLEMS IN THE FIELD AND LABORATORY. NORMAL HEADLIGHT ANGLES WERE SIMULATED WITH A VERTICAL ILLUMINATOR ON A MICROSCOPE. INTERNAL FRACTURES IN BEADS ARE MORE DETRIMENTAL TO LIGHT RETROREFLECTION THAN ARE BUBBLES, IMPURITIES, OR NONROUND BEADS. KANSAS GLASS BEAD SPECIFICATIONS HAVE BEEN CHANGED AND HAVE RESULTED IN A LOWER UNIT PRICE.
