  • unit weight of railroad ballast

    Loose ballast tends to have a unit weight of 90–100 lb/ft 3 (1.44–1.6 Mg/m 3), while that for compacted ballast is approximately 110 lb/ft 3 (1.76 Mg/m 3) . In Table 3.7, fouling index refers to the amount of ballast contamination. While this is a small change in unit weight, the associated engineering behavior changes distinctly.

    Distributing weight. A key job for ballast is to transmit the weight (or "load") of the track and, more significantly, the trains passing over it, to the subgrade. These loads produce pressures averaging 100 pounds per square inch underneath each tie, far greater than earthen subgrades can bear on a repeated basis without settling.
