To reduce degradation of the ballast, a very stiff semi-plastic polyurethane can be used that mimics the plastic behaviour of wooden sleepers; the ballast stones are pressed into the surface of the sleeper, increasing contact area. Typically, these pads are 7 mm (0.28 in) to 10 mm (0.39 in) thick.

However, ballast deterioration and fouling are major issues in the railroad industry, and can be caused by repeated loadings, which lead to the crushing of the 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.

In the first case, ballasted tracks consist of a pair of rails, sleepers, and fastenings systems, supported by the ballast layer. The main advantage lies in their low construction cost and their good drainage performance, but a regular maintenance routine is always required ( Nimbalkar et al., 2012; Sadeghi et al., 2018 ).
