With regards to the aforementioned railway substructure, ballast plays a crucial role in maintaining serviceability of the track and ensuring its structural capacity (AlQadi et al. 2008, AlQadi et al. 2010). The fouling process causes degradation of the original substructure, and can compromise the performance of the railway track system.
