Abstract: During the past 25 years there has been a large increase in the use of rock fill materials for the construction of high dams and embankments. The South Pacific (SPD) Laboratory of the U.S. Army Corps of Engineers (CE) has been engaged in developing equipment and methods to determine the strength and deformation properties of such materials since 1953. This report presents summaries of previously published but not generally available reports prepared by the SPD Laboratory dealing with the influence of gradation, confining pressure, relative density, and engineering properties of individual aggregate particles on the consolidated-drained strength and deformation properties of gravelly materials. Also presented in the report are results of additional unpublished laboratory investigations performed on rock fill materials by the SPD Laboratory dealing with the influence of end restraint and particle shape on consolidated-drained characteristics and with the influence of particle size on one-dimensional consolidation characteristics.
