Maintenance to restore the design level is usually by tamping. In this process, the track is raised and vibrating tines inserted into the ballast to squeeze it horizontally in the direction of the track, raising the level of the ballast surface. This reduces the density and disturbs the structure of the ballast, which has become established ...
The main source for ballast gradings in North America is the American Railway Engineering Association.s (AREA) Manual for Railway Engineering.

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 ...

Ballast railway tracks consist of a series of parallel rails supported by wooden or concrete sleepers, which are laid on a bed of crushed stone or gravel called ballast. The ballast provides stability, drainage, and support to the tracks, helping distribute the weight of the trains evenly and preventing the rails from shifting.
Graham Plowman. 2852 posts · Joined 2006. #7 · Jan 23, 2012. The colour of ballast really depends on what type of stone it is (Granite or Limestone), which quarry it came from and how long it has been in use. This means it could be any colour from pinkish white through to dark grey with every grey/brown tone in between!

An often-underestimated function of ballast is its contribution to drainage. By offering essential drainage capabilities, ballast prevents water accumulation on the track. This not only enhances the track's durability but also mitigates potential issues related to waterlogging. Types of Ballast: A Detailed Exploration 1. Broken Stone Ballast ...
Railway ballasts are broken pieces of hard rock within the grain size range of 25mm -60mm, over which the railway tracks are laid. Quarries in dolerite, greywake, shale, pebbles and granitic rock formations are some of the major sources of large stones that may be selected as railway ballast based on a range of properties.
Ballast is packed around, above, and below the railway sleepers. It helps with drainage as well as holding back or keeping down weeds and vegetation. It also takes the compression load of the track, locomotives, and rolling stock. The ballast physically holds the track in place & prevents its movement.
