Railroad Ballast (Rock): Specifications, Sizes, Background
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.

Evaluation of the Strength of Railway Ballast Using
2016-1-23 For this purpose, four types of railway ballast materials; i.e., basalt, marl, dolomite and trachyte were tested in point load test apparatus using different size fractions and shapes of particles. The following main conclusions can be drawn from this study: By increasing the size of ballast particles, the point load strength index decreases.

RESILIENT RESPONSE OF RAILWAY BALLAST
The resilient responses of five typical open-graded aggregate materials (dolomitic limestone, blast-furnace slag, granitic gneiss, basalt, and gravel) that are used for railway ballast were measured in a triaxial cell. Three levels of compaction and seven stress levels were used. The results were used in regression analyses to develop equations ...
