Abstract : Laboratory experiments were performed with a specil 'closed-system' side-freezing cabinet in which completely saturated soil samples were subjected to alternate freeze-thaw cycles without surcharge. A vertical or nearly vertical freezethaw plane was obtained in the side-freezing cabinet. The soil used was a straight graded noncohesive material with 14% finer than the No. 200 (0.074 mm) mesh sieve. According to frost criterion based only on gradation, the soil would be classified as a 'never frost-heaving moraine soil' or 'non-frost-susceptible'. All experiments were run for 20 and 22 cycles. Freezing rates used were as follows: 30.0 mm/hr; 33.0 mm/hr; and 4 .0 mm/hr. The initial dry density was approximately constant for each test at 1.8 g/cm3 or 112.4 lb/ft3, and complete saturation was maintained in the tests. (Author)
