Interpretive Summary:

Technical Abstract: Lime treated soils are increasingly utilized in earthen structures to reduce shrink and swelling of expansive clays and improve slope stability. In this study, an earthen embankment will be constructed to investigate failure processes of a lime-treated earthen embankment during overtopping of a 3.0 m3/s flow. Prior to embankment construction, lime treatment methods will be optimized to reduce soil erodibility as measured by jet erosion tests conducted on standard proctor samples prepared with varying levels of moisture content and percent lime. The cross-section of the embankment will be trapezoidal with a 3:1 (H:V) side slope. The embankment height, width at crest, and length will be approximately 1.3 m, 1.8 m, and 15 m, respectively. To simulate an embankment repair after construction, only the downstream slope of the embankment will be treated with lime and overlain by a 0.5 m thick layer of untreated compacted soil. Break widening rates will be quantified using digital video monitoring and water levels in the forebay and tailwater will be monitored using pressure transducers.
