STUDYING THE BEHAVIOUR OF CRUSHED STONE RAILWAY BALLAST

The crushed rocks of the railway ballast are subjected to repeated loads due to train traffic. Most of the forces are taken by a relatively small portion of rocks, which are located in a volume underneath the rail fastenings. In this study, a combined experimental and simulation method is introduced, which applies a load that results similar forces compared to the real ones acting in that
