The small-strain behavior and effects of stress path rotation angle of Hawthorn Group (HG) sands in Central Florida are examined in this paper. A series of directional-stress-probe tests were conducted on high-quality HG sand samples extracted from the deep foundation test site (DFTS) at the University of Central Florida (UCF). The small-strain response was studied under undrained and drained triaxial conditions following compression and extension stress paths using internal instrumentation, bender elements (BE), and Hall effect (HE) displacement transducers. For the entire testing program, the stress history of the material was reproduced during the reconsolidation stage in order to isolate the effects of stress path rotation angle. The discussion is centered on the small-strain behavior with emphasis on shear, bulk, and cross-coupling moduli degradation. The results showed that the small-strain stiffness behavior of this material is affected by the stress path rotation angle.
