ACCELERATED TESTING OF TRAFFIC ZONE PAINTS
THE LACK OF PERFECT AGREEMENT IN THE SERVICE DURABILITY TESTS CAN PROBABLY BE EXPLAINED BY THE VARIATION IN WEATHER CONDITIONS IN THE VARIOUS LOCALITIES IN WHICH THE PAINTS WERE APPLIED. IT IS GENERALLY CONCEDED THAT WATER IS THE AGENT WHICH GREATLY AFFECTS THE DURABILITY OF TRAFFIC POINTS. THE TESTS USED WERE VARIOUS METHODS OF ABRASION AND A FLEXIBILITY TEST. NINE PAINTS WERE USED IN THE INVESTIGATION; 6 WHITE AND 3 YELLOW PAINTS. THE ABILITIES OF THE LABORATORIES TO RATE THE PAINTS, ON THE BASIS OF THE LABORATORY RESULTS, IN THE ORDER OF RELATIVE DURABILITY AS DETERMINED BY THE PREVAILING SERVICE RESULTS, VARIED FROM 33 TO 78 PERCENT CORRECT RATINGS. IN GENERAL, THE ABRASION TESTS GAVE MORE RELIABLE INFORMATION ON DURABILITY THAN DID THE FLEXIBILITY TESTS. THE GENERAL CONCLUSION THAT CAN BE DRAWN FROM THIS INVESTIGATION IS THAT NO ONE LABORATORY TEST, OR COMBINATION OF THE LABORATORY TESTS THAT WERE USED ARE SUFFICIENT TO EVALUATE CORRECTLY THE RELATIVE DURABILITY OF TRAFFIC PAINTS. /AUTHOR/
