System descriptions for initial bench scale testing of stone-soil material desorption 1996-1997. Density determined from whole sample mass. Porosity determined by phase diagram (1-(mass of solids/specific gravity)) for 1m3 of material. Volumetric moisture percentage (θ) at varied matric tensions measured as moist weight prior drying. Hydraulic Conductivity measured with compaction permeameter.
