ballast deformation and degradation under different conditions. A owchart of the experimental programme, conducted by the authors on railway ballast based on largescale triaxial testing, is shown in Fig. 1. Ballast behaviour. Ballast is a freedraining granular material used as a loadbearing material in railway tracks. It is composed of

Track ballast (usually crushed stone), as it is known, is another important part of railroad infrastructure. Although it may just look like plain ole gravel this stone plays a vital role in acting as a support base for the railroad ties and rails as well as allowing for proper drainage of water away from the rails (which is why the stone is always sloped downward and away from track).
Track ballast is typically made of crushed stone, although ballast has sometimes consisted of other, less suitable materials, for example burnt clay. The term ballast comes from a nautical term for the stones used to stabilize a ship. Track ballast forms
