Book Description
The present paper is one of four prepared for presentation at the January 1959 Annual Meeting of the Highway Research Board and intended to bring out, in the original papers and through prepared discussions, the present and latest basic knowledge concerning frost heave and frost action in soils in relation to pavements. The basic papers cover the factors of (1) water availability, (2) penetration of freezing temperatures, (3) freezing mechanism of soil-water systems, and (4) soil and material types. The present paper covers the last-named of these factors. It reviews the elements which are significant in annual freeze and thaw action in soils and pavement supporting materials. In general, it does not attempt to cover special physical factors encountered only under permafrost conditions. However, the principles brought out herein are, in general, basically applicable not only to frost action which occurs in areas of purely seasonal freezing, but also to that which occurs in the zone of annual freeze and thaw in permafrost regions. (Author).

Book Description
Experiments conducted at USA CRREL in recent years indicate that the two weeks or so required for the frost susceptibility testing of soils with previous procedures can be shortened considerably. Results of these experiments show that useful frost heaving data can be obtained in a matter of 2 or 3 days by a more rapid freezing technique. Results of experiments in which soil specimens were exposed to a constantly maintained temperature are presented. Data show that heave rate in laboratory experiments is a variable, not a constant, of a soil and is strongly dependent upon the heat extraction rate. The important role of frost susceptibility testing and soil evaluation for highway design is discussed. The suitability of equipment for use in conducting frost-heaving tests is also discussed.

Book Description
An outline is given two current theories on the freezing of water in soils. The classification and description, standardized in the United States and Canada, of frozen soils, leads to some laboratory data on the mechanical behavior of frozen soils. The monograph concludes with the application of linear viscoelastic theory to typical field problems. (Author).
