SW—Soil and Water: Effects of Bulk Density and Moisture …
These relationships were developed for six typical field moisture contents ranging from 3 to 22% d.b., and various dry bulk density levels ranging from 1·15 to 1·82 Mg m −3. Results showed that all mechanical properties increased with dry bulk density, except the internal friction angle that was an independent property.
