Dynamic behaviors of coarse granular aggregates in high-speed railway subgrades

With the increase in the running speed and axle load of trains, there has been a greater demand for high-speed railway (HSR) subgrades. Coarse granular aggregates are suitable materials for the HSR subgrade filler. Hence, the study of the dynamic characteristics of coarse granular aggregates is impo...
