Size and Section of Ballast in Railway – Civil Engineering

2019-12-9  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 ...
