Abstract : The report contains an extensive discussion of the mechanics of frost heave, based on a literature survey. The laboratory evaluation, by use of freezing apparatus developed by the U.S. Army's Cold Regions Research and Engineering Laboratory, supplemented by various physical-property tests, of unsatisfactory base course materials from three sources is also reported. The freezing tests were made on samples of: (1) unaltered material and (2) on specimens for which the normal percentage smaller than 0.02 mm. was reduced by either removing some of the material passing the No. 200 sieve or adding material retained on the No. 4 sieve. General conclusions were that: (1) some of the pavement distress in the sampled sections was not the result of detrimental frost action in the base course; (2) reduction in fines reduced the frost susceptibility of the materials; and (3) in addition to percentage smaller than 0.02 mm., gradation or particle size distribution, capillarity and permeability affect the frost susceptibility of materials, and should be further investigated.
