Regionalized Feasibility Study of Cold Weather Earthwork.
A regional approach is used to delineate areas in Canada, Alaska, and the conterminous United States, in which selected earthwork operations should receive careful consideration for winter execution. Soil texture and soil form or physical site environment are deemed important physical factors in the...

A regional approach is used to delineate areas in Canada, Alaska, and the conterminous United States, in which selected earthwork operations should receive careful consideration for winter execution. Soil texture and soil form or physical site environment are deemed important physical factors in the economic feasibility of cold weather earthwork. A compatible modern physiographic map of Canada, and the conterminous United States compiled for this study is presented. The physiographic section is the basic areal unit used in the evaluation of winter earthwork feasibility. A generalized soil texture map for Canada, Alaska, and the conterminous United States is developed from geologic and pedologic information. Summary maps showing areally significant soil forms and related feasible earthwork operations are presented. A general discussion of the importance of the soil form in the economic feasibility of winter earthwork is included.
