Produktbeschreibung

Angesichts der zunehmenden Verkehrsdichte und -lasten auf Schienenwegen einschl. Tunnelbauwerken sowie des Ausbaus der Hochgeschwindigkeitsnetze weltweit kommt die Betonbauweise der Festen Fahrbahn zunehmend zum Einsatz. Nach ersten Erprobungen in den 1970er-Jahren und mehr als vier Jahrzehnten Forschungs- und Entwicklungsarbeit auf dem Gebiet der Festen Fahrbahn wurde ein Entwicklungsstand erreicht, der die Anwendbarkeit der Festen Fahrbahn als Alternative zum Schotteroberbau bestätigt. Dieses Buch spiegelt den aktuellen Stand der Technik der Festen Fahrbahn wider und beschreibt die grundlegende Bemessung der Tragplattenkonstruktion. Es werden wichtige konstruktive Hinweise für die Feste Fahrbahn auf dem Erdbauwerk und im Bereich von Tunneln gegeben. Es folgt eine Beschreibung der technischen Historie zur Entwicklung der Festen Fahrbahn auf Brücken und den daraus resultierenden Erkenntnissen für die Brückenkonstruktion. Der aktuelle Stand der Festen Fahrbahn im Weichenbereich, wichtige Hinweise zu konstruktiven Details der Entwässerung, den Übergängen und der Befahrbarkeit mit Straßenfahrzeugen und Erfahrungen zur Instandhaltung runden das Thema ab. Seit 1906 begleitet der Verlag Ernst & Sohn mit dem Beton-Kalender die Entwicklung des Stahlbeton- und Spannbetonbaus. Dieses Buch sollte das Fortschreiten des Eisenbetonbaus jährlich begleiten, und zwar so lange, bis die "stürmische Entwicklung", so der erste Herausgeber Fritz von Emperger (1862-1942), der Bauweise ein Ende gefunden hätte. Ausgewählte Kapitel des Beton-Kalender werden in der neuen englischsprachigen Reihe BetonKalender Series dem internationalen Markt zur Verfügung gestellt.

Autorenporträt

The authors are extensively involved in planning, operating and inspecting, designing and testing as well as updating specific rules as well as R&D. Univ.-Prof. Dr.-Ing. Stephan Freudenstein has been a full professor at the Chair and Institute of Road, Railway and Airfield Construction at the Technical University of Munich and director of the test institute of the same name in Pasing, Munich, since 2008. After graduating in civil engineering at TU Munich in 1995 and working at Heilit + Woerner Bau AG, Stephan Freudenstein became a research associate at TU Munich's Chair and Institute of Road, Railway and Airfield Construction in 1997. In 2002 he joined Pfleiderer Infrastrukturtechnik GmbH, now known as RAILONE GmbH, in Neumarkt in der Oberpfalz, Germany. While there, he headed up the technology and development department. He was responsible for prestressed concrete sleepers and the technical side of various ballastless track projects in Germany and farther afield. The main focus of Prof. Freudenstein's research is the structural design of road and rail superstructure systems and aviation surfaces. He is a member of numerous German and European technical standard committees and committees of independent experts. Dr.-Ing. Konstantin Geisler graduated in civil engineering at TU Munich in 2010. He was awarded his doctorate by that university in 2016 and now works in academic research at TU Munich's Chair and Institute of Road, Railway and Airfield Construction. Dipl.-Ing. Tristan Mölter studied civil engineering at TU Darmstadt. Since 1999 he has been responsible for noise control, bridge equipment and provisional bridges at the technology and plant management department of Deutsche Bahn DB Netz AG in Munich. He is the chair of the structural engineering commission (FA KIB) at VDEI (association of German railway engineers) and a member of numerous German and European technical standard committees and committees of independent experts. Dipl.-Ing. Michael Mißler studied civil engineering at TU Darmstadt. As a team leader and project manager he is responsible for the ballastless track technique and track stability at the track technology management dept. of Deutsche Bahn DB Netz AG in Frankfurt on the Main, Germany. He has pushed on the development of ballastless track for Deutsche Bahn since 1999. In the context of his central technical responsibility he is a member of numerous German and European technical standard committees and committees of independent experts. Dipl.-Ing. Christian Stolz studied civil engineering at Cologne's University of Applied Sciences. Since 2010 he has been responsible for ballastless track engineering in the track technology management department of Deutsche Bahn DB Netz AG in Frankfurt/Main, Germany. He is a member of numerous German and European technical standard committees, e.g. DIN Standards Committee Railway NA 087-00-01 AA "Infrastructure", DIN subcommittee "Ballastless track" and CEN TC 256/SC 1/WG 46 "Ballastless Track".
