Abstract: The granulometric range used has a direct influence on the life of the ballast layer when subjected to the load generated by rail traffic. However, in Brazil, we have only two size ranges to be used. The publications related to the subject matter under study express the need for a continuous grain size strip, different from the ones usually used in our railways. This more continuous band would provide less deformation and a reduction of degradation, granting a longer ballast life. To verify the influence of gr… Show more

“…By the granulometry test, we have some parameters such as D10, D30, D50, D60, which are respectively: 0.006, 0.02, 0.151 and 0.18. From these parameters, we have the result of CNU (Coefficient of Non-Uniformity) and C c (Coefficient of Curvature), which are presented below in Table 1 (Hilário and Fernandes, 2021).…”
