The testec samples were classified as GW to SC material ac- cording to the USCS. Table 2. Compaction parameters. *the closeness of approach of a measurement to the true valu of the quantity measured ** the smallest division on the instrument readout scale Table 3.

The steady state was reached when the volume change-time plots for both controllers reached the same slope. A constant pressure value within each controller was a further evidence that the steady state condition has been reached. Table 4. Permeability tests.
