C047 Coarse Grain Soil Vibration Compactor

The maximum density of coarse-grained soil and giant-grained soil was measured, and the maximum dry density of non-cohesive free-drained coarse-grained soil and giant-grained soil, including rockfill materials, was determined by surface vibration compaction.
