Improving existing railway subgrade stiffness – case study of ground improvement techniques

Last updated on 11 October 2013 3:35

In a parametric study Hunt, in his report on the EUROBALT II project, shows that track stiffness and its variation has a significant effect on the cost of maintenance. For optimum operational conditions he suggests that the stiffness should be in the range 150 kN/mm to 200 kN/mm (per sleeper)...
