In Chapter 1, “Soil aggregate, plasticity, and classification,” a more detailed description of the relationships between the maximum and minimum void ratios of granular soils is provided. The American Association of State Highway and Transportation Officials (AASHTO) soil classification system has been added to this chapter. Sections on soil compaction procedures in the laboratory, along with recently developed empirical relationships for maximum dry unit weight and optimum moisture content obtained from Proctor compaction tests, have been summarized.
• Chapter 4, “Stresses and displacements in a soil mass: Threedimensional problems,” has new sections on vertical stress due to a line load of finite length; vertical stress in Westergaard material due to point load; line load of finite length; circularly loaded area; and rectangularly loaded area.
• The fundamental concepts of compaction of clay soil for the construction of clay liners in waste disposal sites as they relate to permeability are discussed in Chapter 6, “Permeability.”
• Several new empirical correlations for overconsolidation ratio and compression index for clay soils have been added to Chapter 8, “Consolidation.”
• Chapter 9, “Shear strength of soils,” provides additional discussion on the components affecting friction angle of granular soils, drained failure envelopes, and secant residual friction angles of clay and clay shale. Also added to this chapter are some new correlations between field vane shear strength, preconsolidation pressure, and overconsolidation ratio of clay soils.
• Chapter 10, “Elastic settlement of shallow foundations,” has been thoroughly revised and expanded.
• Discussion related to precompression with sand drains has been added to Chapter 11, “Consolidation settlement of shallow foundations.”
• The parameters required for the calculation of stress at the interface of a three-layered flexible system have been presented in graphical form in the Appendix, which should make interpolation easier.
