Railway track settlements - a literature review by Tore Dahlberg Division of Solid Mechanics, IKP, Linköping University, SE-581 83 Linköping, Sweden Abstract Railway tracks (rails and sleepers) are normally laid on a sub-structure that consists of two or more layers of different materials. The top layer (below the sleepers) is a layer of ...
The ballast supports and levels the track. Ballast also helps keep undesirable vegetation from growing in the tracks. The load that rail cars place on the track is large. Each axel on loaded rail car places a load of up to 71,500 lbs. on less than an inch of track. The railroad track structure spreads the load to the ballast …
Results show that, with the same track superstructure and subgrade condition, the rail support modulus of test track in steel slag ballast section is 1.64 times greater than that of limestone ballast, and the compressive contact pressure of sleeper and ballast in limestone ballast was almost 1.39 times greater than steel slag ballast.

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. This also serves to hold the track in place as the trains roll over it.

A. Prior to placing ballast on track subgrade, perform a final check of the condition of the track subgrade as to line, grade, cross section, and compaction. 1. Verify that track subgrade or subballast does not vary more than 1/2 inch from the design elevations and the line cross sections. 2.
Uses. Angular crushed stone is the key material for macadam road construction which depends on the interlocking of the individual stones' angular faces for its strength. Crushed natural stone is also used similarly without a binder for riprap, railroad track ballast, and filter stone.It may be used with a binder in a composite material such as concrete, tarmac, or asphalt concrete.

71,500 lbs. on less than an inch of track. The railroad track structure spreads the load to the ballast below. Because ballast material is angular crushed rock, the crushed ballast locks together as a matrix, which transfers these large loads from track structure to the sub ballast below.
As nouns the difference between gravel and ballast is that gravel is (uncountable) small fragments of rock, used for laying on the beds of roads and railroads, and as ballast while ballast is (nautical) heavy material that is placed in the hold of a ship (or in the gondola of a balloon), to provide stability. As verbs the difference between gravel and ballast
