  • Size and Section of Ballast in Railway – Civil Engineering

      Size of Ballast The size of the ballast used in railway track varies from 19 cm to 51 cm The stone of size larger than 51 cm is not preferable due to poor interlocking property The bestrecommended ballast is that which contains stones ranging in size from 19 cm to 51 cm The size of the ballast mainly depends upon the type of sleeper

  • Railroad Ballast (Rock): Specifications, Sizes, Background

    Track ballast (usually crushed stone), as it is known, is another important part of railroad infrastructure Although it may just look like plain ole gravel this stone plays a vital role in acting as a support base for the railroad ties and rails as well as allowing for proper drainage of water away from the rails (which is why the stone is always sloped downward and away from track)
