Single particle crushing test. Several different factors such as angularity, uniformity of gradation, lower particle strength, coarseness, stress level, and anisotropy govern the crushing of railroad ballast particles (Bohac et al., 2001). The most important of all these factors is the crushing strength of ballast.
