Research on Railroad Ballast Specification and Evaluation

Quarried stone ballast should be obtained from com­ petent strata of reasonable thickness. The extent of the rock deposit should be sufficient for economic ballast production. A large variety of rock types are used as ballast. In general, the fine hard min­ eral-grained unweathered aggregates make the best ballast.

Rail Track Ballast Tarmac

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.
