A new parameter for classification and evaluation of railway ballast
The physical condition of railway ballast should be regularly inspected and accordingly, ballast cleaning should be carried out to maintain the safe operation of a track. This paper reviews current methods commonly used for evaluating the degree of ballast fouling, and due to their limitations, a new parameter — "relative ballast fouling ratio"— is proposed. …

Rail Track Ballast
Rail track ballast serves as a bed for rail tracks and provides drainage and strength for heavy loads carried by trains. Ballast is the description for the aggregate beneath the rail track. The track ballast forms the track bed that suports the rail track load and provides water drainage. Rail ballast aggregate is typically 30-50mm aggretate.
