1. Broken stone Ballast. Broken stone is a widely used ballast in railways. It is obtained by crushing hard stones like granite, hard trap, quartzite etc. In lieu of broken stones, limestone and sandstone can also be used. It is suitable for high-speed railway tracks. The broken stone selected as ballast should be hard, tough and non-porous.

Bulk Density is carried out in accordance with AS 1141.4. The test gives the density (mass per unit volume) of the material either being in stockpile or when loaded into a bulk container for delivery. In the case of ballast the test is used to calculate volumes required as material is mostly delivered to a project by rail cars.
The specic gravity and bulk density of the ballast are two properties that play pivotal roles in rail track safety. Bulk density is a function of the particle specic gravity and the void ratio. Two methods can be employed to increase the bulk density the use of denser particles, and a broader gradation.
