This thesis is an investigation of the collapse behavior of two types of compacted loessial soil. Different stress paths will be followed to define the collapse behavior due to changes in net vertical stress and matric suction for loess specimens acquired from two locations in West Tennessee. The two loessial soils chosen have different grain size distributions, which result in differences in soil structure which should impact the collapsibility of the soil. The soil-water characteristic curve will be measured for the soils in the non-collapsed and collapsed conditions. The volume change behavior will be evaluated using results of collapse tests, measured soil-water characteristic curves, unsaturated soil mechanics volume change theory, and related references. The differences in the test results between the two soil types will be interpreted in light of the differences in grain size distributions. Recommendations for future research on collapsibility will also be presented.
