Crushed stone aggregate materials are commonly used for basal embankment support on soft subgrades or for horizontal drainage in soft soils. When the drainage material is constrained by earth pressure and water pressure, it changes to an unsaturated water-permeable state. If the pore water pressure decreases as the compaction of the soft ground increases, the water does not drain through the ...
