Abstract:

Railroads have begun to use under tie pads (i.e., pads) and under ballast mats (i.e., mats) in railroad tracks to better distribute train loads, reduce track support stiffness, and increase tie-to-ballast contact area. Track locations with a shallow ballast layer and numerous tunnels and bridges are areas of stiff track support that may benefit from pad and mat use.
