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).

Geotechnical properties of ballast and the role of ...

The specific 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 specific gravity and the void ratio. Two methods can be employed to increase the bulk density: the use of denser particles, and a broader gradation.

Density is also called as unit weight of substance. It is represented by symbol called row ( p). Density represents the degree of compactness of material. If the material is of more density, it is more compacted material. Density is defined as the ratio of mass to volume. p = m/v Units = kg/m 3 or lb/ft 3 Conversion: 1 kg/m 3 = 0.624 lb/ft 3.

Unit of Density - SI Units, Other Units and FAQ

To find the density of an object, measure the mass of the material and divide it by the volume it covers, since the density of water is 1 gm/cm³ - the ratio of the density of the material to that of water is 1:£ (Density of water is 1 gm/cm³ at 4°C.) For example, the density of gold is 19.32 g/cm³, and so the specific gravity is 19.32.
