Geomechanical Modelling of Railroad Ballast: A Review ...

 · Periodic ballast maintenance is needed which is a time and cost expensive activity. Understanding the mechanical behaviour of railroad ballast leads to better design and efficient maintenance. From the literature, there are two main approaches used to understand the mechanical behaviour of railroad ballast; large scale experimental and modelling.

Ballast

Ballast. Ballast is a bed of pebbles placed on the railway track. Its main role is to transmit the stresses, generated by the passage of trains, to the ground, without the latter becoming packed down or deformed. But it also makes it possible to attenuate the vibrations caused by trains and to prevent vegetation from growing on the tracks.

Track ballast

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.
