CONSOLIDATION AND PERMEABILITY OF TWO COMPACTED SCHIST SAPROLITES

Mica schist saprolites that occur extensively in southwestern Nigeria have been undesirable as subgrade and fill materials. In this study, samples were taken from depths of 6.5 m near Ilesha, Nigeria, and quartz schist saprolites from another location in Nigeria. Samples of the two saprolites were compacted using 3 energies in the laboratory, and samples compacted at their respective optimum moisture contents were then subjected to the oedometer and permeability tests. The results, together with the basic geotechnical characteristics of the saprolites are evaluated and compared. The maximum dry densities for the saprolites were high, and the MDDs increased and compressibility decreased appreciable with increased compactive energy while the permeability was virtually constant. The saprolites may therefore be better suited for use a subbase and fill materials when compacted at higher energies.
