PEDOTECHNICAL ASPECTS OF ORGANIC SOIL CLASSIFICATION AND INTERPRETATION

Exploration and classification of organic soils in transportation research is done primarily to predict performance and impacts of construction activities. In the preliminary stages, published maps are included in the data base. There is a continuing need for improved methods of interpreting surveys performed by mapping agencies as the state of their art develops. For Canadian soil survey applications, the pedotechnical setting sheet has been proposed. The setting sheet is a modular framework in which soils and landscape data pertinent to engineering are presented graphically. The site-specific appearance of the mapping unit data has resulted in slow acceptance. This question is addressed using the case history of a geotechnical site appraisal for embankment construction over highly organic soils. A feel for soil behavior is developed as the site investigation proceeds. In retrospect, it is seen that the graphic data, which are superimposed on the setting sheet background, pertain to the central concept of the mapping unit, and they are presented in this form in order to pass on the feel for soil behavior to others, with minimum effort and cost.
