Ballast plays a vital role in transmitting and distributing train wheel loads to the underlying sub-ballast and subgrade. Bearing capacity of track, train speed, riding quality and passenger comfort all depend on the stability of ballast through mechanical interlocking of particles. Ballast attrition and breakage occur progressively under heavy cyclic loading, causing track deterioration and ...

Track Ballast Stabilisation Track maintenance work and line speed restrictions significantly affect schedules and are expensive and disruptive to the public, train operators and asset owners. Much of it is down to poor track geometry and a loss of vertical and horizontal alignment of the rails, caused by ballast deformation.

Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. Ballast also holds the track in place as the trains roll over it.

This layer of ballast is made of small, coarse rocks of various shapes and materials. It is important that these rocks be irregularly shaped and not uniform, as they will pile up and hold stronger. This ballast will fill in all the gaps between and underneath the sleepers and rails, providing a strong base for the track as a whole. Typically, a ...
