| Summary: | Towards a reassessment of muskeg, an appraisal of the problems of muskeg showing the complexity of the subject and the implications for engineering is presented based on field experience and a study of the literature. A theory of the origin of muskeg is given from the engineer's point of view by considering climatic, biotic, and geologic factors. Muskeg research in other countries is reviewed with emphasis on Canadian research. The Radforth Muskeg Classification System, its application to problems and modifications are discussed. Empirical data on the engineering properties of peat are broadly described in four main categories: (1) index properties, for identification; (2) strength and deformation properties; (3) thermal properties; and (4) geophysical properties. Engineering problems, construction equipment, and costs to be considered in vehicle trafficability, road construction, corrosion and drainage operations, and frozen muskeg and permafrost construction when muskeg is involved and fully discussed. Comprehensive conclusions and recommendations on the present state of knowledge of muskeg and needs for further research are outlined. |
