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.
Because the purpose of Railroad Ballast is to improve drainage. Ordovician Dolomitic Limestone is the perfect source material. Ordovician Dolomitic Limestones physical properties enhance drainage and its interlocking shape helps to stabilize and disperse the load of the overall track structure. Railroad Ballast in Agricultural Construction
Rail Ballast, otherwise known as railway ballast and track ballast is an aggregate formed from crushed stones such as granite and other smaller materials such as clay. Primarily utility and construction companies use railway ballast to provide a level base for rails and sleepers.
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.
Jun 04, 2020 Ballast is a common trackbed structure in the railway transport system, which is used to support track sleepers. A layer of crushed stones will be laid on the roadbed before the tracks are laid, which will then be compacted. Then sleepers and tracks will be laid. Distribute the pressure of the sleepers to the roadbed.
Sep 30, 2011 D. Unload ballast as close as possible to the point of use so to prevent unnecessary handling. Do not handle ballast more than two 2 times from the quarry to the track unless otherwise approved by the Engineer. Pick up excess ballast and ballast that is mixed with soil or fouled during distribution and replace with new ballast.
Jan 15, 2010 Historically, the ballast a railroad used was what was available on line, hence limestone in the south, ganite in the west, cinders or dirt anywhere, etc, as you note. As demands for a better track structure developed, many things changed. Ties got bigger, rail got heavier and the need for a good solid base to build it on got more critical.
Jan 29, 2010 First, ballast holds the track in place and keeps the ties and rails from shifting. Second, it helps drain water away from the track. Third, ballast evenly distributes the weight of the rails and equipment to the subgrade. Finally, it keeps the track level and in alignment. The type of material used for ballast varies between railroads.

Jan 01, 2001 Railway track formations generally consist essentially of a layer of coarse aggregate, or ballast, in which the sleepers are embedded see Fig. 12.1. The ballast may rest directly on the subgrade or, depending on the bearing capacity, on a layer of blanketing sand. The layer of ballast is intended to provide a free draining base which is stable enough to maintain the track aUgnment with

Ballast also acts as a support base for the railroad track structure giving it strength and rigidity but also allowing for flexibility when trains pass over. Limestone or quartz is often most used as ballasting because it is a hard stone that will lock together providing for extra strength.
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 limestone.
