Public ISBD Titre : Mechanics of ballasted rail tracks : a geotechnical perspective Type de document : texte imprimé Auteurs : Buddhima Indraratna ; Wadud Salim, Auteur Editeur : London : Taylor and Francis Année de publication : 2005 Collection : Balkema proceedings and monographs in engineering, water and earth sciences Oeuvres / Expressions : 0-415-38326-3 Importance : 226 p. Présentation : ill. Format : 26 cm ISBN/ISSN/EAN : 978-0-415-38329-5 Note générale : Bibliogr. Index. Langues : Anglais (eng) Mots-clés : Voies ferrées;Ballast (Chemins de fer);Routes;Sols;Roches, Mécanique des;Bitume;Railroad tracks;Ballast (Railroads);Soil amendments;Rock mechanics;Geosynthetics Résumé : Presents the triaxial testing of ballast including the strength, deformation and degradation aspects of fresh and recycled ballast under monotonic and cyclic loading. The effectiveness of geosynthetics in stabilising recycled ballast is examined. A stress-strain constitutive model for ballast incorporating particle breakage is presented. Contents : Introduction - Track structure and loading - Factors governing ballast behaviour - State-of-the-art triaxial testing of ballast - Behaviour of ballast with and without geosynthetics - Existing deformation models - A new constitutive model for ballast - Track drainage and use of geosynthetics - Track maintenance - Recommended ballast gradations.
