COMPUTERIZED INFORMATION SYSTEM FOR INDIANA SOILS

A comprehensive information storage system for Indiana soils is being operated on a computer at Purdue University, West Lafayette, Indiana, and at the Division of Materials and Tests of the Indiana State Highway Commission. Information is being collected that includes geotechnical, pedological, and geological data from records of subsurface investigations obtained during the period 1950-1978. Test data from more than 2500 soil samples have been stored and, within the year (1978), it is anticipated that data for an additional 6000 soil samples will be recorded. The data have been evaluated by various statistical methods. Results indicate that the range in values to be expected for a given soil parameter depends on the particular physical property and on the population from which the soil has been sampled. Some soil properties appear to be inherently more variable than others. To illustrate applicability, correlations have been made by using the information relative to physiographic unit and parent material. The grouping of soils by physiographic unit and parent material. The grouping of soils by physiographic regions or origin of parent material (or both) suggests that the predictability of some parameters can be improved for certain combinations of parameters and soil groups. Specifically, prediction equations were generated for compression index, compression ratio, and unconfined compressive strength for certain soil populations. It is also possible to predict compaction test values, standard American Association of State Highway and Transportation Officials maximum dry and wet densities, and optimum moisture contents for selected physiographic and parent-material groupings.
