Essential technical information for building on expansive soils--complete with practical, proven design methods. Expansive Soils examines factors that influence the design offoundations and pavements built on expansive soils, and exploreskey design procedures and remedial measures that address thesefactors effectively. Backed by the authors' extensive research andexperience --including interviews with practicing engineers workingwith expansive soils --this authoritative volume is an importantreference text for geotechnical and foundation engineers,geologists, construction professionals, and students. Easy to understand and apply, Expansive Soils contains: * Site investigation techniques for identification andclassification of expansive soils * Heave prediction methods using different types of data --withrigorous treatment of soil suction theory and measurement,oedometer tests, and more * Alternative design procedures for drilled pier and slab-on-gradefoundations, highway and airfield pavements * Treatment and chemical stabilization techniques --including salttreatment; moisture barriers; lime and cement stabilization; andother procedures * Remedial measures such as drainage control, and removal withreplacement and compaction control * Sample problems illustrating practical applications.

Differential swelling and shrinkage of foundation soils are responsible for considerable damages to buildings and other structures in many parts of the world. One of these regions is in Jackson, Mississippi, and the surrounding area, where many types of structures have been damaged from movements of the underlying Yazoo clay formation. Field test sections, each containing an instrumented 100-ft-square area covered with an impermeable material simulating a lightweight structure, have been planned for five regions. The first test section was constructed near Jackson in October 1969 in an area underlain by the Yazoo clay formation. Results of field and laboratory investigations conducted prior to construction were used to estimate the amount of heave anticipated in the test area. The climate at Jackson is warm and humid. The test section was constructed on a moist soil profile. Negative pore water pressures of about 1 ton/sq ft have been measured in the laboratory in undisturbed samples of Yazoo clay. Accumulative heave of less than 0.04 ft measured during 1-1/4 years of observations shows a pattern of very slow change that may require years before the maximum heave is developed. (Author).

Vertisols, one of the eleven established soil orders, are clay soils with unusual and interesting properties. They cover more than 350 million hectares of land in the world and in tropical Africa alone there are over 100 million hectares. Because of their very small particle size and high surface area, these soils have higher physical and chemical reactivity than other soils. Their interaction with agrochemicals/industrial wastes, has been, increasingly, the subject of research especially in the last two decades. Vertisols create special problems when used for engineering purposes. This book is intended to provide comprehensive and state-of-the-art information about Vertisols worldwide. Special attention is given to the use and management of soils such as fertilizer use, crop selection, soil tillage, water restriction on land including irrigation, and soil erosion. A special chapter has been added to deal with geotechnical engineering of Vertisols. Vertisols have great potential for agricultural production but many, especially in the developing world, are underutilized due to a lack of understanding regarding their behaviour and management. This book is written by leading scientists worldwide. It is expected that this monograph will be of great use to soil scientists and agronomists, graduate and senior graduate students. Improvement of their management may solve the current food deficiency in the world.
