Summary
To investigate the performance of artificial frozen soil materials with a fused interface, split tension (or 'Brazilian') tests and unconfined uniaxial compression tests were carried out in a low temperature environmental chamber. Intact and fused specimens were fabricated from four different soil mixtures (962: clay-rich soil with bentonite; DNA1: clay-poor soil; DNA2: clay-poor soil with vermiculite; and DNA3: clay-poor soil with perlite). Based on the 'Brazilian' test results and density measurements, the DNA3 mixture was selected to closely represent the mechanical properties of the Alaskan frozen soil. The healed-interface by the same soil layer sandwiched between two blocks of the same material yielded the highest 'Brazilian' tensile strength of the interface. Based on unconfined uniaxial compression tests, the frictional strength of the fused DNA3 specimens with the same soil appears to exceed the shear strength of the intact specimen.
