AIRFIELD MARKING PAINTS - 1. EFFECT ON CRACKING OF SLURRY SEAL

THE BASIC CAUSES OF EARLY FAILURE OF AIRFIELD MARKING PAINTS AND THE DETERIORATION OF UNDERLYING SLURRY SEAL AND ASPHALTIC PAVEMENT ASSOCIATED WITH THESE PAINTS ARE BEING STUDIED. DATA AND STATISTICAL ANALYSES ARE PRESENTED ON THE INITIAL CRACKING OF SLURRY SEAL ALONG THE EDGES OF STRIPS OF 20 EXPERIMENTAL PAINT FORMULATIONS. SUCH CRACKING WAS GENERALLY FOLLOWED BY EDGE LIFTING AND THEN BY LOSS OF ADHESION OF SLURRY SEAL TO THE UNDERLYING ASPHALTIC PAVEMENT. STRIPES OF PAINTS CONTAINING CHLORINATED RUBBER CRACKED EXTREMELY RAPIDLY, ESPECIALLY SUCH STRIPES WITH A DOUBLE THICKNESS. ALKYD PAINTED STRIPES GENERALLY HAD LESS CRACKING THAN OLEORESINOUS PAINTED STRIPES. POORER PERFORMANCE OF ALKYD PAINTS WAS ASSOCIATED WITH A SOLVENT OF HIGH BOILING RANGE, AND POORER PERFORMANCE OF OLEORESINOUS PAINTS WITH SOLVENTS OF LOW AROMATICITY. THE ADDITION OF A SLIGHT AMOUNT OF CARBON BLACK TO THE TEST PAINTS RAISED THE TEMPERATURES OF STRIPES TO ONLY A VERY SLIGHT EXTENT, WHICH IMPROVED THE PERFORMANCE OF SOME TEST PAINTS BUT LOWERED IT FOR OTHERS. STRIPES WITH GREATER FLEXIBILITY GENERALLY HAD LESS EDGE CRACKING.
