  • Influence of Size and Shape Properties of Railroad

    Railroad ballast is uniformly graded coarse aggregate placed between and immediately underneath the ties to provide drainage and structural support for the loading applied by trains In the United States, several ballast gradation recommendations are suggested by the American Railway Engineering and MaintenanceofWay Association (AREMA) Most of these recommended uniform gradations have
