Description: This project involves the determination of residual shear strength of Colorado claystones obtained using both ring shear and direct shear devices. This project also involves the development of a large-scale direct shear device with large-displacement capabilities representative of residual conditions for most soils.
In addition, a cubical cell capable of testing a tire shred-soil or fiber reinforcement- soil mixture as an elemental cube has been developed. This project allows determination of the effects of reinforcement on soil improvement and anisotropy.
