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).

These facts introduce errors in the quality assessment for large-size aggregates where the material must be laboratory crushed in order to obtain the required particle sizes. The new Norwegian standard for large-size aggregates specifies testing of 10–14 mm samples for quantifying the resistance to wear and fragmentation for aggregates of all sizes.
