Ballast refers to the gravel or crushed rock paved on the road or railway subgrade it is mainly used in railway subgrade. Ballast is one of the main components in the railway transportation system used to support the railway sleeper and rail track. Before laying tracks a layer of ballast is needed to pave on the railway subgrade.

Dec 09 2015nbsp018332Providing resilience in the rail fastening system on top of the sleeper and the use of resilient pads under the sleeper can reduce overall track stiffness distribute vertical track loads and attenuate the dynamic forces transmitted into the ballast. This can lead to lower rates of track degradation and therefore longer maintenance intervals.
