SOIL CONSIDERATIONS IN SITING HIGHWAYS, AIRPORTS, AND UTILITY CORRIDORS

This is a review of sources of soils data used to identify soil properties that influence the location, design and performance of transportation systems and utility corridors. The use an value of soil surveys and other sources of soils data in planning these systems and corridors are also discussed. Soil surveys and geologic surveys which supplement one another are outlined. Interpretation of aerial photographs have been extensively used to identify surface features, including soil properties of importance in planning transportation systems. Engineering soil surveys are generally conducted after a corridor or preliminary location for a route has been established. Highway test data (sampling and testing of soils at intervals along the route) provide a vast amount of soil information and have been organized by some States to aid in planning transportation systems. One such State, South Dakota, found, on statistical study of the data that each soil had a distincitive range in test results. The kinds of soil information of most value in transportation planning are discussed and include: composition, erodibility, chemistry, moisture regime, depth, density, slope and kinds of geologic formation. The actual use of soil surveys in planning transportation systems (in route selection, planning for more detailed study, planning drainage requirements, planning erosion control, recognizing excavation and grading problems, locating sources of sand and gravel for subbase, selecting possible chemical stabilizers for fine-grained soils, locating sources of topsoil, locating rest areas, and planning secondary roads, streets and parking lots is discussed. The use of soil surveys in planning utility corridors and the cost and other savings resulting from the use of soil surveys are also discussed.
