The ballast should be renewed from time to time, because due to continuous hammering the ballast converted into the powder form. This powder along with dust, sand ashes from locomotive form an impervious layer and prevent the ease flow of water through ballast. Ballast maximum size is 1.9 to 5.0 cm with some reasonable proportion of intermediate sizes.
– 90-92% reused but not in railway industry • These figures represent a lot of train movements • Reuse on site saves transport costs as well as stone • Reuse on the railway allowed but only on low category lines (where there is little demand!) • Techniques that prolong ballast life are clearly desirable

However, ballast deterioration and fouling are major issues in the railroad industry, and can be caused by repeated loadings, which lead to crushing ballast that is in contact with ties. Upward migration of subgrade particles into the ballast layer can increase fouling in the ballast and decrease drainage through the ballast layer.
Track ballast should never be laid down less than 150 mm (6 inches) thick; and high-speed railway lines may require ballast up to 1 ⁄ 2 metre (20 inches) thick. An insufficient depth of ballast causes overloading of the underlying soil, and in unfavourable conditions overloading the …

With the recycled ballast proportion increasing, the shear strength and coordination number reduce and the displacements get larger. This research provides a foundation for the application of recycled ballast, and on the other hands, adding fresh ballast can be a solution to reinforce deteriorated ballast bed.

Ballast cleaning removes this worn ballast, screens it and replaces the "dirty" worn ballast with fresh ballast. The advantage of ballast cleaning is that it can be done by an on-track machine without removing the rail and sleepers, and it is therefore cheaper than a total excavation.
