Abstract:

Personnel of the Geotechnical and Structures Laboratory, U.S. Army Engineer Research and Development Center, Vicksburg, Mississippi, conducted a laboratory investigation to characterize the strength and constitutive property behavior of an adobe from Scottsdale, Arizona. Twenty-one mechanical property tests, consisting of 12 triaxial compression TXC tests, two uniaxial strain UX tests, and seven unconfined compression UC tests, were successfully completed. In addition to the mechanical property tests, nondestructive pulse-velocity measurements were performed on each specimen. The TXC tests exhibited a continuous increase in maximum principal stress difference with increasing confining stress. A compression failure surface was developed from the UC and TXC test results. The UX stress-strain responses exhibited continuous increases in compaction up to the applied peak stresses and did not achieve full saturation.
