Indian railway ballast standards do not address the requirements of bulk density and particle density for the rail ballast. The Australian standard [] specifies that the bulk density of ballast material shall not be less than 1,200 kg/m 3 and that the particle density on a dry basis of ballast material shall not be less than 2,500 kg/m 3.In order to ensure the stability of the track and the

To start with, the stones that you see lying close to the railway tracks are collectively called track ballast. It basically forms the trackbed on which the rail sleepers are kept. Track ballast is packed between the sleepers, in the areas below, and on the sides of railway tracks.

Both the trap rock and granite in the deposit can be uniformly crushed for diverse applications, including railroad ballast, landscape stone, chips for asphalt or concrete, and sealcoating and baseball warning track materials. Initially, TR&G’s products were used on the oblong railroad track loop laid across some 70 acres of the quarry.

Size of Ballast. The size of the ballast used in railway track varies from 1.9 cm to 5.1 cm. The stone of size larger than 5.1 cm is not preferable due to poor interlocking property. The best-recommended ballast is that which contains stones ranging in size from 1.9 cm to 5.1 cm. The size of the ballast mainly depends upon the type of sleeper

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.

railway ballast The function of ballast in railway track. Ballast is a common trackbed structure in the railway transport system, which is used to support track sleepers. A layer of crushed stones will be laid on the roadbed before the tracks are laid, which will then be compacted. Then sleepers and tracks will be laid.
