Bituminous Ballast & Applications in Railway Construction
The rail ballast absorbs the train weight and distributes it from the rails to the sub grade, thereby avoiding any deformation. The rapid decay of the railroad level which occurs with traditional ballast construction is mainly due to the unsatisfactory "fatigue behaviour" of the ballast; this is mostly due to embankment settling.
