RAILROAD BALLAST SIZING AND GRADING Transportation
Railroad ballast gradings tend, not only in North America but also world wide, to be uniformly graded (i.e., single sized with the opening of the major percent passing sieve being 1.5-3 times the size of the percent retained on sieve). Herein a laboratory examination of ballast top size and grading are made in the triaxial apparatus.
Subballast an overview ScienceDirect Topics
Track ballast should never be laid down less than 150 mm thick; high-speed railway lines may require ballast up to half a meter thick. The ballast plays different roles: it ensures the regularity and safety of the sleepers and rail that lie on it, it drains the rainwater rapidly, and it contributes to reducing vibrations and noise.

200651While ballast provides track with firm support, it is not absolutely rigid. Each axle of a loaded, 100-ton car will deflect even the stiffest track about one-tenth of an inch, and relatively soft track will give as much as a half-inch. Stones of 1 to 3-1/2 inches in size are preferred. Hard crushed furnace slag, some kinds of dense lava
