Behavior of railroad ballast under monotonic and cyclic loading / William F. Anderson in Journal of geotechnical and geoenvironmental engineering, Vol. 134 N°3 (Mars 2008)  

Public ISBD [article]  inJournal of geotechnical and geoenvironmental engineering > Vol. 134 N°3 (Mars 2008) . - pp. 316–327 Titre : Behavior of railroad ballast under monotonic and cyclic loading Type de document : texte imprimé Auteurs : William F. Anderson, Auteur ; Peter Fair, Auteur Année de publication : 2008 Article en page(s) : pp. 316–327 Note générale : Geotechnical and geoenvironmental engineering Langues : Anglais (eng) Mots-clés : Ballast Railroad tracks Triaxial tests Static Cyclic Volume change Résumé : A relatively new method for mechanized maintenance of railroad ballast (stoneblowing) puts a layer of single size stone between the ballast and each tie creating a two-layer gravel support. To get a better understanding of the behavior of this arrangement series of large diameter, triaxial tests have been carried out on single size and layered specimens. A new method of quantifying particle breakage during testing has been developed, and a conceptual model used to explain the combined effects of shearing and breakage on observed specimen behavior.
