: A hypo-plastic approach for evaluating railway ballast ...

2017-9-14 Repetitive or cyclic rail loading deteriorates the engineering properties of the railway ballast by particle crushing and rearrangement. Most of the classical elasto-plastic models are unable to predict such ballast degradation despite successfully predicting the overall load–deformation behavior during cyclic densification. In this context, the present study delivers a novel hypo-plastic ...

2021-8-9 Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.

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.
