Ballastless Tracks (eBook, ePUB)

• Format: ePub

Produktbeschreibung

Due to increasing traffic flows the extension of transport infrastructure with rail roads and high speed lines is an ongoing process worldwide. Ballastless track systems with concrete slabs are used more and more. Following the first trials in the 1970s and more than four decades of R&D work on ballastless track, the level of development is such that it can be confirmed that ballastless track is suitable for use as an alternative to ballasted track. This book makes a contribution to the state of the art of ballastless track by describing the basics for designing the ballastless track. Important advice is provided regarding the construction of ballastless track on earthworks and in tunnels. There is also a description of the technical history of the development of ballastless track on bridges and the ensuing findings for bridge design. The state of the art of ballastless track for switches, important information on details concerning drainage, transitions, accessibility for road vehicles and experience gleaned from maintenance round off the work. Selected chapters from the German concrete yearbook are now being published in the new English "e;Beton-Kalender Series"e; for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn "e;Beton-Kalender"e; has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in "e;ferro-concrete"e; structures until - as the book's first editor, Fritz von Emperger (1862-1942), expressed it - the "e;tempestuous development"e; in this form of construction came to an end. However, the "e;Beton-Kalender"e; quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since.

Stephan Freudenstein studierte Bauingenieurwesen an der TU München. Nach einer mehrjährigen Tätigkeit bei der Heilit + Woerner Bau AG wurde er 1997 wissenschaftlicher Assistent am Lehrstuhl für Bau von Landverkehrswegen der TU München. Im Jahr 2002 wechselte er zur Pfleiderer Infrastrukturtechnik GmbH in Neumarkt/Opf., der späteren RAILONE GmbH, wo er die Abteilung Technik und Entwicklung leitete und für das Geschäftsfeld Spannbetonschwelle sowie diverse Feste-Fahrbahn-Projekte auf nationaler und internationaler Ebene technisch verantwortlich war. Seit 2008 ist Prof. Freudenstein Ordinarius am Lehrstuhl für Verkehrswegebau an der TU München und Direktor des gleichnamigen Prüfamtes in Pasing. Die Schwerpunkte seiner Forschungstätigkeit liegen auf der konstruktiven Gestaltung von Straßen- und Eisenbahnoberbausystemen sowie Flugbetriebsflächen. Er arbeitet in zahlreichen nationalen und europäischen Normenausschüssen und Sachverständigenausschüssen mit. Dr.-Ing. Konstantin Geisler studierte Bauingenieurwesen an der TU München (2010). Er promovierte dort im Jahr 2016 und ist wissenschaftlicher Mitarbeiter am Lehrstuhl und Prüfamt für Verkehrswegebau. Dipl.-Ing. Tristan Mölter studierte Bauingenieurwesen an der TU München. Seit 2000 ist er Arbeitsgebietsleiter Lärmschutz, Brückenausrüstung, Hilfsbrücken im Technik- und Anlagenmanagement Brückenbau (I.NPF 21 (T)) bei der DB Netz AG der Deutschen Bahn in München, Germany. Er ist Vorsitzender des Fachausschusses Konstruktiver Ingenieurbau (FA KIB) des VDEI und arbeitet in zahlreichen weiteren technischen Ausschüssen mit. Dipl.-Ing. Michael Mißler studierte Bauingenieurwesen an der TU Darmstadt. Als Team- und Projektleiter ist er seit 1999 fachlich verantwortlich für die Themen Feste Fahrbahn und Gleislagestabilität in der Abteilung Technologiemanagement Fahrwegtechnik bei der DB Netz AG der Deutschen Bahn in Frankfurt/Main. Von Seiten der DB Netz AG hat Hr. Mißler die Weiterentwicklung der Festen Fahrbahn maßgeblich vorangetrieben. Im Rahmen seiner zentralen technischen Verantwortung arbeitet er seit dem in zahlreichen deutschen und europäischen Expertenausschüssen. Dipl.-Ing. Christian Stolz studierte Bauingenieurwesen an der TH Köln. Seit 2010 ist er Projektreferent Oberbautechnik Feste Fahrbahn in der Abteilung Technologiemanagement Fahrwegtechnik bei der DB Netz AG der Deutschen Bahn in Frankfurt/Main.
