Abstract

The research program incorporates concepts involving collapsible soil behavior and unsaturated soil mechanics in an attempt to obtain a better understanding of collapsible soil behavior in general. Although previous research has focused on these areas of study separately, it appears that the two topics have never been fully incorporated together during a research investigation. In order to evaluate maximum collapse potential, 18 collapse tests were conducted on specimens with varying initial conditions. From the collapse test results, contour plots expressing maximum collapse potential were developed for both soils on a typically plot of dry density as a function of moisture content. The state variable that is considered of greatest relevance to unsaturated soils, matric suction, is determined for each collapse test specimen to see if a correlation between maximum collapse potential and the state variable exists. Recommendations for future research on collapsible soils will also be presented.
