CLASSIFICATION AND LABORATORY TESTING OF ARTIFICIALLY FROZEN GROUND

The proposed guidelines for classifying artificially frozen ground are based on the Unified Soil Classification System, with the addition of salinity evaluation. For testing frozen soils in the laboratory, it is recommended that: Axial loading strain rates be 0.1 and 1%/min; constant stress loadings for creep testing be 70, 50, 30, and 10% of the strength values obtained from the constant strain rate test performed at 1%/min; temperatures of the tests be -2 deg, -5 deg, and -10 deg C; the test specimen shape and size be a right circular cylinder with height-to-diameter ratio of 2 or more and a diameter be at least 10 times that of the largest soil particle size; specimen end caps be lubricated where possible; and the test loading system have a stiffness at least five times that of the test specimen.
