This study investigates the plastic shakedown limit of railroad ballast, a critical parameter for long-term performance under cyclic loading. A series of eight triaxial tests on 150 × 300 mm specimens, replicating particle size distribution according to AREMA No. 4 standards, was conducted. The results reveal a significant dependence of the shakedown limit on both stress ratio and confining stress. Consequently, a confining stress-dependent shakedown limit is proposed. This approach aligns well with findings from PFC2D simulations reported in literature. The established shakedown limit offers a valuable tool for railway pavement designers, enabling them to evaluate material behavior under variable loading scenarios, transcending the limitations of single stress state analysis.
