While this edition differs from the two previous editions in several respects, including the addition of a second author, the objective remains the same: to present the material simply, and to direct it toward the undergraduate level of instruction and the beginner in this field.
The scope of the book has been expanded into geotechnical areas to offer an introductory appreciation of landforms, weathering, and clay mineralogy in relation to soil occurrences, properties, and uses. This approach derives from a concept developed some years ago by the authors and their associates at that time, Dr. T. Y. Chu, Professor W. W. Williams, and the late Dr. D. T. Davidson: that every soil has a past, a present, and a future, each stage depending on those preceding. The concept may be further elaborated by dividing the history of a soil into a geological past during which the rocks and sediments were formed, and a pedagogical past whereby these were weathered into soils. History determines the present composition of the soil—its structure, particle sizes, mineralogy, etc., which in turn determine its present engineering properties such as strength, compressibility, and plasticity. These latter directly influence the usefulness of the soil in engineering.
