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.

Railway track settlements - a literature review

2005-6-15  Railway tracks (rails and sleepers) are normally laid on a sub-structure that consists of two or more layers of different materials. The top layer (below the sleepers) is a layer of railway ballast. Below the ballast there might be layers of sub-ballast, a formation layer and/or the subground (the formation). Historically, the ballast layer
