Aggregate Testing Equipment As aggregates are used as a component of many construction materials, asphalt, concrete and also raw as road base or ballast there are many methods for characterising its geometry, mechanical an physical properties and its resistance to wear.
Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. Ballast also holds the track in place as the trains roll over it.
