AbstractSeveral specimens of artificially frozen sand (ASTM C-109) were prepared to evaluate different testing procedures and techniques used to determine the mechanical properties of frozen soils. Two methods of preparation of fully saturated frozen sand specimens, described by other investigators, were compared. Compaction by a rodding technique and saturation under vacuum produced a uniform degree of compaction and saturation upon freezing. The most critical part of the preparation procedure leading to physical variability between specimens was found to be the time during freezing and machining. This time span must be kept constant to minimize the effects of sublimation.
