Railway ballast degradation - STRC

2015-5-18  Ballast particles degradation can be understood as grain crushing in terms of breakage and abrasion and is a decisive factor in ballast behaviour (Indraratna et al., 1998). According to Lekarp et al. (2000), crushing is a progressive process starting at relatively low stresses and results in gradual changes in granular fabric and packing.
