Design for Railroad Ballast and Subgrade Support

Gerald P. Raymond

Open publisher page 28 citations

Abstract

A rational design method for railroad ballast and subgrade support based on the Casagrande classification of soils is presented. Ballast increments for upgrading existing track for soft spots and increased wheel load are also examined, as are ballast cleaning undercutting depths. As far as can be judged existing practices for ballast depths concur with the conclusions.
