Based on the Turkish and international railway ballast specifications, all railway basalt aggregates fulfil the specification requirements for the use in all types of railway applications (Table 7). When the data given in Table 7 and basalt used in this study were compared, it was found that all samples could be used as ballast materials.

Railroad ballast serves as a bed for railroad tracks and provides track stability, drainage, and support of significant loads carried by railcars. In addition, it deters the growth of vegetation and allows for track maintenance to be performed more easily. Ballast is produced from natural deposits of granite, trap rock, quartzite, dolomite or ...

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.

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).
