MANUFACTURE OF PERMANENTLY SKID-RESISTANT COATINGS (LABORATORY TESTS)

HERSTELLUNG DAUERHAFT GRIFFIGER BESCHICHTUNGEN (LABORVERSUCHE)

AN ATTEMPT IS TO BE MADE TO FIND RELATIONS BETWEEN THE COMPOSITION OF PLASTIC MORTARS AND PERMANENT SKIDDING RESISTANCE OF COATINGS MANUFACTURED WITH THEM. FOR THIS PURPOSE VARIOUS PLASTIC MORTARS CONTAINING EPOXY RESIN AND POSSIBLY PMMA ARE TO BE PRODUCED. THE AGGREGATES USED ARE TO BE VARIED IN TYPE, HARDNESS, IMPACT AND WEAR STRENGTH, AND IN SHAPE, SIZE AND SIEVE LINE. THE MOST FAVOURABLE BINDER- AGGREGATE RATIO IS TO BE DETERMINED FOR EACH OF THESE VARIATIONS. MOREOVER THE INFLUENCE OF A DEFINED POROSITY OF THE PLASTIC MORTAR AND THE ADHESION BETWEEN BINDER AND AGGREGATE ON THE SKIDDING RESISTANCE OF THE COATING IS TO BE EXAMINED. WEAR TESTS AND MEASUREMENTS OF SKIDDING RESISTANCE ARE TO BE CARRIED OUT ALTERNATELY ON THE SAMPLES OF THE COATING. FOR THIS A WEAR MACHINE IS NECESSARY WHICH PRODUCES SURFACE ABRASION ON EVEN SAMPLES AND IMITATES THE WEAR STRESS UNDER TRAFFIC AS ACCURATELY AS POSSIBLE. CURRENTLY AVAILABLE WEAR MACHINES (FOR EXAMPLE THE SRT EQUIPMENT) ARE TO BE USED.
