RAILWAY TRACK FOUNDATIONS

LES COUCHES D'ASSISE DE LA VOIE FERREE

For the construction of new lines, the SNCF has established rules for laying track foundations with appropriate characteristics and sufficient thickness. These rules take account of present knowledge on soil mechanics in the surface layers under moving loads, and also of "rule-of-thumb" and theoretical considerations and experience gained in motorway construction, particularly as regards classification of track foundations. After an analysis of general principles and typical track bed structures, a study is made of protection against freezing and maintenance of existing track beds.
