EXPERIENCES FROM ON-SITE BRIDGE SURFACING TRIALS

ERFAHRUNGEN AUF VERSUCHSBAUSTELLEN FUER BRUECKENBELAEGE

IT IS REPORTED THAT ROLLED ASPHALT WAS FIRST USED IN 1975 AS PROTECTION AND SURFACING TO CONCRETE BRIDGES HAVING CARRIAGEWAY WIDTHS IN EXCESS OF 4.5 M CROSSING AGRICULTURAL AND FOREST TRACKS AND ACCESS ROADS, IN ORDER TO SAVE ON THE USE OF GUSSASPHALT. AT THIS TIME THE PROTECTIVE LAYER HAD TO BE ADDED BY HAND AS OTHERWISE THE TWO COAT ADHESIVE SEALANT MADE OF BITUMEN-COATED DIMPLED ALUMINIUM FOIL WOULD HAVE BEEN DAMAGED. IN A SECOND TRIAL IN 1976 A METAL TAPE SEAL OF TWO COATS OF BARE DIMPLED ALUMINIUM SHEETS WAS DIRECTED TO BE USED. AS A RESULT OF THE ACTIVE ADHESIVE SURFACE OF THE SEALANT IT WAS NOT POSSIBLE TO COVER IT. THE MIX THEREFORE HAD TO BE POURED IN THE ABOVE-HEAD METHOD AND EVEN THEN MANUALLY PLACED. BOTH TRIAL SURFACES WILL NOW BE INTENSIVELY OBSERVED UNTIL 1978.
