Measuring the strength of railway ballast | New Civil Engineer

The variability in particle strength, as measured by diametral compression between flat platens, is responsible for the size effect on average strength, and the distribution of particle strengths satisfies the Weibull distribution. Single particle crushing tests have been performed on 10mm-14mm ballast particles, and 37.5mm-50mm particles.
