Abstract:

This study focuses on understanding the mechanical and deformation behaviors of Wyoming bedrocks to improve the design and construction of transportation infrastructure in the state. Fifty-six samples were tested under different confining stresses. Test rock samples are mostly sandstone (30%), siltstone (23%), shale (14%), and others (33%). Triaxial and uniaxial compression tests are conducted using GCTS RTR-1500 rapid triaxial rock testing equipment on hard rocks and GeoJac triaxial equipment on soft and soil-like rocks. Physical properties such as moisture content, porosity, and specific gravity of tested specimens are measured before compression testing. Laboratory compressive tests are performed to measure the stress and strain of each rock specimen, and elastic properties are determined from the linear stress-strain relationship. Shear strength parameters, such as cohesion and friction angle, are also determined. Tensile strength and material constant for each rock sample were also determined.
