GUSSASPHALT SURFACINGS IN WEST BERLIN /GERMAN/

THE AUTHOR REPORTS ON EXPERIENCES WITH AND KNOWLEDGE OBTAINED FROM GUSSASPHALT ON ROADS IN BERLIN. CURRENTLY ALMOST A THIRD OF ALL THE SURFACINGS ON THE WEST BERLIN URBAN ROAD NETWORK (APPROX. 8.3 MILLION SQUARE METRES) ARE MADE OF GUSSASPHALT. EXPERIENCES OBTAINED OVER MANY YEARS HAVE LED TO THE WELL KNOWN " BERLIN RECIPE" FOR THE COMPOSITION OF THE MINERAL MIXTURE. AT PRESENT THE PARTICULAR WAY IN WHICH THE GUSSASPHALT MUST BE MIXED IN ORDER TO WITHSTAND HARSH BRAKING FORCES WHICH OCCUR AT BUS- STOPS AND TRAFFIC LIGHTS IS BEING STUDIED. PREVIOUSLY THE STANDARD CONSTRUCTION METHOD CONSISTED OF A CEMENT BASE WITH A GUSSASPHALT SURFACING, BUT IN RECENT YEARS PREFERENCE HAS BEEN GIVEN TO THE FLEXIBLE CONSTRUCTION METHOD HAVING A BITUMEN-BOUND BASE, A BITUMINOUS BASECOURSE AND A GUSSASPHALT SURFACING. WITH A POINTLESS CONSTRUCTION WITH A SCREED THE SEAMS ARE HEATED WITH INFRARED EQUIPMENT AND THEN SMOOTHED OVER. THE TOP OF THE GUSSASPHALT SURFACING IS NO LONGER TEXTURED, AND THE SURFACE CHIPPINGS ARE ONLY PRESSED IN WITH A SMOOTH ROLLER. /FG/RRL/
