REQUIREMENTS OF EQUIPMENT FOR TESTING THE ADHESION STRENGTH AND RESISTANCE TO WEAR OF PAINTS AND MATERIALS FOR CARRIAGEWAY MARKINGS

ANFORDERUNG AN GERAETE ZUR PRUEFUNG DER HAFT- UND ABRIEBFESTIGKEIT VON MARKIERUNGSFARBEN UND -MASSEN

TEARING-OFF TESTS HAVE BEEN UNDERTAKEN WITH THE ADHESION APPARATUS TYPE A 933 OF THE FIRM HERION-WERKE KG, STUTTGART. THERE WERE NO USEFUL RESULTS OBTAINED ON CONCRETE, AS THE BREAK BETWEEN THE MARKING MATERIAL AND THE CONCRETE IS NON-UNIFORM AND IN SOME CASES CONCRETE PARTICLES ARE RIPPED OUT. THE TESTS WERE EXTENDED TO GLASS PLATES. HERE DIFFERENCES WERE FOUND BETWEEN THE VARIOUS MARKINGS, DEPENDING ON THE DRYING PERIOD. THE TESTS ARE TO BE CONTINUED ON AN INSTRON APPARATUS.
