Limestone Ballast. Limestone aggregate is often chosen as the limestone ballast used to support the rails in railway construction. As with roadbuilding, limestone aggregate is popular with track layers due to its strength, durability, and excellent drainagepromoting qualities.
It was proved that the rail support modulus of the test track with steel slag is times higher than that of limestone ballast, and the compressive contact pressure of sleeper and ballast in limestone ballast was almost times greater than steel slag ballast .
For history''s sake ballast has its earliest beginnings as simple limestone blocks, which actually sometimes pulled double duty as both the support base and railroad track structure. In the 1840s true ballast, or crushed stone, as we know it today began to be widely used and was soon found to be far superior to the old method.

History of ballast? Trainorders Railroad Center. Good quality track ballast is made of crushed natural rock with particles between 28mm and 50mm in diameter;[5] a high proportion of particles finer than this will reduce its drainage properties, and a high proportion of larger particles result in the load on the ties being distributed improperly.[5]
