This book provides a broad coverage of recent advances in the characteristics and treatment of expansive soils. There are nine parts each with specific chapters. It starts with an overview section (Part 1) on the nature, identification, and classification of expansive soils. Parts 2 and 3 deal with volume change characteristics and swelling potential measurements, respectively. Pail 4 covers advanced techniques for swelling potential assessment. Such tests are important for assessing the actual swelling potential of the soil and estimating ground heave. Part 5 on site characterization presents field measurements of soil swelling potential and suction. The next three pails deal with lime stabilization- cement stabilization, and other treatment methods. Chemical stabilization, for example, has gained wide attention as a successful technique for treating expansive soils. In the final section (Part 9), the performance of engineering structures built on expansive soils such as buildings, houses, embankments, and roads, is evaluated. Remedial measures used to address soil swelling problems are also described.
