The Effect of Compacted Prestress on Compacted Shale Compressibility
The compressibility of the compacted New Providence Shale was studied as a function of the compaction variables, viz., water content, compactive foot pressure, compaction effort, and compacted density. All samples were compacted in the kneading device to simulate low, standard and modified impact energy levels. All compression and/or heave was one-dimensional. Compactive prestress was found to increase with compaction pressure and to decrease with compaction water content. To simulate the effects of the service environment, compacted samples were confined and saturated with measurement of volume change. Such changes were either increases (heave) or decreases (settlement or collapse). The prediction equations developed in this report are of the type needed to predict settlements or heaves within compacted shale embankments in service.
