Track ballast Wikipedia

Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. Ballast also holds the track in place as the trains roll over it.

Ballast migration is a process whereby the ballast gradually moves down the super elevated (canted) track and gathers in a heap against the low rail. Field measurements using geophones are being used to gain insights into the mechanisms by which the ballast migrates, with the aim of better understanding the mechanisms involved in order to

Introduction to Railroad Track Structural Design

• Ballast quality and ability to resist crushing forces (ballast degradation is the number 1 cause of ballast fouling) Some railroads use different track modulus (u) values in design. For example, Spring u may be used for rail bending and ballast depth, but Winter u used for rail seat forces. Other railroads may use a single u value.

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.

Ballastless track Superstructure :: Trackopedia

The negative impact of the ballast on the service life of the track led to initial designs of ballastless track. The ballast is replaced by sub-layers of concrete or asphalt which, unlike ballast, have no or only slight plastic deformation. The lack of elasticity of these layers is compensated by the conscious use of elastic components.

Minimum Depth of ballast = Db = (S-w)/2. For example, if en sleepers are used in track laying with sleeper density as (n +7), the sleeper spacing is 65 cm and width of sleeper is 25 cm. Then, the minimum depth of ballast from above formula works out to be 20 cm which is minimum depth of ballast generally prescribed on Indian Railways.
