Track stiffness assessment

Last updated on 08 March 2013 2:21

A good track support and its homogeneity are very important parameters for long-term stability of track geometry and a good life cycle cost of the track. The overall vertical support is provided by various substructure layers including the ballast, subballast, and subgrade layers. Weak modulus and non-uniform support from these...
