The main objective of this research was to characterize the drained and undrained stress-strain behavior of normally consolidated silts and clayey- silts. The results of this research were also used to develop a database of hyperbolic stess-strain and Mohr-Coulomb strength parameters for silts and clayey-silts. This research involved extensive drained and undrained triaxial tests on silt specimens with varying clay contents. The percentages of clay used in the silt mixtures were 0, 10, 30, and 50. The effect of density was investigated by compacting the triaxial test specimens at Standard Proctor relative compactions of 85, 90, 95, and 100. This report summarizes the test results and the resulting hyperbolic stress-strain and Mohr-Coulomb strength parameters for the various silt mixtures considered.
