COMPACT ASPHALT "FLUDOBIT" APPROVED FOR USE IN BRIDGE CONSTRUCTION

KOMPAKTASPHALT "FLUDOBIT" IM BRUECKENBAU BEWAEHRT

COMPACT ASPHALT "FLUDOBIT" IS A ROLLED ASPHALT WHICH LIES OUTSIDE THE TVBIT 3/72 WITH REGARD TO ITS RESIDUAL VOIDS RATIO, PROPORTION OF CHIPPINGS AND BITUMEN TYPE. IT IS PRODUCED WITH AN INDUSTRIALLY MANUFACTURED FILLER (SO-CALLED COMPACT COMPONENT) WHICH HELPS TO IMPROVE THE PLACING OF THE MIX, THE EXTREMELY HIGH RIGIDITY OF THE BITUMINOUS MORTAR AND THE HIGHER COHESIVE PROPERTIES IN THE FILLER BITUMEN MIX. THE SPECIAL PROPERTIES OF "FLUDOBIT" ARE DESCRIBED: ITS SPECIAL DENSITY WHEN BEING PLACED AT TEMPERATURES OF 130 - 150 DEG C AND ITS LASTING NON-SKID QUALITY. IN THE SPHERE OF BRIDGE CONSTRUCTION THIS TYPE OF SURFACING HAS NOT YET BEEN WIDELY ADOPTED, IN SPITE OF IT BEING EMINENTLY SUITABLE. THE PARTICULAR LOADING CONDITION OF BRIDGES (WHETHER OF STEEL OR CONCRETE CONSTRUCTION) IS DESCRIBED. THE TECHNICAL DETAILS OF ORTHOTROPIC CARRIAGEWAY SLABS (THE TEMPERATURE SENSITIVITY OF THE STEEL CONSTRUCTION AND ITS PROTECTIVE SURFACE) ARE REFERRED TO, AS ARE THE TECHNICALITIES INVOLVED IN SURFACING CONCRETE BRIDGES AND TEMPORARY BRIDGES. SUCCESSFUL CASES OF THE APPLICATION OF "FLUDOBIT" ARE DESCRIBED: FOR EXAMPLE, IN DUSSELDORF FLUDOBIT 0/5 MM WITH 45 KG/M2 IS IN USE ON THE JUELICHER BRIDGE; IN DUISBURG IT ACTS AS A PROTECTIVE LAYER ON THE CITY MOTORWAY (NORD-SUD-STRASSE) WHICH INCLUDES A BRIDGE LENGTH OF 1000 M; IN WURZBURG IT ACTS AS A SEALING PROTECTION AND COVERING LAYER ON A CONCRETE BRIDGE AND HAS THE SAME FUNCTION ON PEDESTRIAN OVERPASSES IN ESSEN.
