Quantifying the impact of subgrade stiffness on track quality and the development of geometry defects
Download2016
Hendry, Michael T., Roghani, Alireza
This paper presents the quantification of the impact of subgrade stiffness on the prevalence of track geometry defects and degradation of track quality indices (TQIs). The data included in this study come from two high-traffic subdivisions [>50>50 million gross tonnes (MGT)/year] in Canada with a...
