Abstract:	In 2005 wurde auf Veranlassung des Bundesverkehrsministeriums das Sandwich Plate System (SPS) für den Einsatz an Fahrbahnen im Brückenbau in Deutschland an einem Pilotprojekt qualifiziert. Fünf Jahre vorher wurde diese 1998 patentierte Technologie durch Kontakte zwischen der RWTH Aachen und der Carleton University in Ottawa, Kanada, in Deutschland bekannt und wissenschaftlich untersucht. Für das Pilotprojekt wurde die Verstärkung der orthotropen Fahrbahnplatte einer Autobahnbrücke der A57 bei Krefeld ausgewählt. Die aus den 1960er Jahren stammende stählerne Fahrbahnplatte des Überbaus erhielt eine Fahrbahnverstärkung aus SPS-Overlay. Mit dieser Aktion des Bundesverkehrsministeriums wurde der Start für die baupraktischen Einsätze dieser neuen, innovativen Tragstruktur gelegt. Nun, mehr als zehn Jahre nach dem Pilotprojekt, werden in diesem Bericht die mittlerweile erfolgten Entwicklungen dargestellt und aktuelle Anwendungen der 22 Jahre alten Grundidee aufgezeigt. Reconstruction of bridge decks and walkways by using Steel-Elastomer-Compound Components. On the initiative of the German Federal Ministry of Transport in 2005, the Sandwich Plate System has been qualified for the use on roadways in bridge construction in Germany on a pilot project. Two years before this 1998 patented technology was known in Germany by contacts between the RWTH Aachen and the Carleton University in Ottawa, Canada, and in the following scientifically examined. For the pilot project, the strengthening of an orthotropic carriageway of a motorway bridge of the A57 near Krefeld was selected. As a native of the 1960s, the steel slab of the bridge superstructure got roadway reinforcement by SPS Overlay. With this action by the Federal Ministry of Transport, the start of the practical building operations of this innovative new support structure was done. Now, more than ten years after the pilot project, present developments and current applications of the 22-year-old basic idea are highlighted in the report.
