Abstract

This paper describes the development of a Meso-scale Oedometer Test System (MOTS) for investigating the volume change behavior of problematic soils. The de novo test system is designed to measure swelling, collapse, and consolidation properties of 100 times larger than conventional samples. This scale allows for an effective capture of soil structure and for understanding the spatial and temporal variability in volume change. Numerical simulations and load-deformation analyses indicated that the test system can safely be loaded up to 1730 kPa: the deformability of the entire assembly was found to be 4 mm. A preliminary test indicated that the apparatus provides a better estimate of soil volume change.
