This report presents the results of permeability tests and swelling pressure tests on samples of a milled refuse at various compacted dry densities. Permeability tests were done with special attention being given to assure saturation of the sample; for this purpose, the sample was flushed with deaired water and was subjected during testing to back pressures as great as 75 psi. The dependence of engineering permeability on dry density is represented in a semi-logarithmic plot by a bilinear relationship showing a very rapid decrease of permeability with increasing dry density values above approximately 37 lbs/cu ft. Swelling pressure tests were done by a method designed to approximate a zero deflection condition. It has been observed that potential swelling pressures increase with increasing compacted density; the highest swelling pressure observed being 600 lbs/sq ft for a dry density of 48.02 lbs/cu ft.
