Frank J. Skudrzyk, Clark R. Barker and Marian Mazurkiewicz over a period of time from February 15 to April 15, 1982 for the University of Alaska, Fairbanks. The scope of the project, established through discussions with Dr. Chris Lambert, representing the UA, was to conduct pilot studies of frozen gravel properties related to underground mining in permafrost: high pressure water jet cutting characteristics and uniaxial compressive test (uniaxial compressive strength and Young's modulus measurement). It has been agreed that the tests would be conducted on an artificial material simulating the frozen gravel.
