THE TECHNOLOGY OF SURFACE DRESSING

TECHNIK DER OBERFLAECHENBEHANDLUNG

SURFACE DRESSING WHICH IN PREVIOUS YEARS HAS BEEN USED MAINLY FOR THE RENEWAL OF BITUMINOUS SURFACINGS, IS USED MORE NOWADAYS IN THE BATTLE AGAINST SMOOTH SURFACES AND ACCIDENTS. IT ENABLES GOOD SURFACE PROPERTIES TO BE PRODUCED ON SURFACE COATINGS LAID IN A MODERN FASHION. ABOVE ALL ELSE, THIS REQUIRES BINDERS WITH IMPROVED THERMAL STABILITY, RESISTANCE TO AGEING AND ELASTICITY, PROPERTIES WHICH THE CLASSICAL BINDERS POSSESS ONLY TO A LIMITED DEGREE. PLASTIC MODIFIED BITUMENS AND TARS HAVE PRODUCED A DECISIVE IMPROVEMENT IN THIS REGARD. EQUALLY DECISIVE ARE QUALITY AND GRANULAR COMPOSITION. THE STONE SHOULD BE DIFFICULT TO POLISH, POSSESS HIGH IMPACT STRENGTH AND RESISTANCE TO WEAR; THE SHAPE OF THE GRAINS IS ALSO IMPORTANT AS IS THE DUST CONTENT, AND THE OVERSIZE AND UNDERSIZE PERCENTAGE. FOR SURFACE DRESSING ON HIGHLY DRESSED SURFACES, ARTIFICIAL AGGREGATES MAY ALSO BE CONSIDERED WITH SUPERIOR WEAR RESISTANCE, STRENGTH AND RESISTANCE TO POLISHING. THESE MODERN SURFACE DRESSINGS MAKE IT POSSIBLE TO USE AGGREGATES WITH A LOWER RESISTANCE TO WEAR AND POLISHING WHERE RENEWAL OF BITUMINOUS OR CONCRETE SURFACINGS IS CONCERNED.
