Soil Stabilization

In recent years the increasing demand for improved construction materials has led to a much wider application of the techniques of soil stabilisation to upgrade natural materials. In the past 25 years, considerable research and development of soil stamilization methods has proceeded in all parts of the world, and from the principles revealed by these studies, and the successes (and failures) in practicr, a clear understanding of sound design for all kinds of soil stabilization has emerged. It is the purpose of this book to state these principles as they apply to practical situations, to show the advantages and limitations of current methods of soil stabilization, and in particular to act as a reference guide to current but semi-arid conditions which characterize a large part of Asutralia. This book deals with the application of stabilization in construction practice, with stabilization in construction practice, with highways, airfields, dams and embankments, building foundations, erosion protection and many other uses. It shoes the means by which the different stabilization response of different soils can be most readily identified, often by simple field observation, and discusses in detail the principle soil stabilizing materials, cement, lime, bituminous compounds, as well as the important stabilizing effects of mechanical admixture of soils. An account of the advantages and disadvantages of the many new soil stabilizers which have been proposed, is given. The machinery and methods by which soil stabilization may be best effected is also explained, and particular attention is given to the design methods and calculations required in practical instances of highway pavement design, slope stability, the grouting of foundations, etc. Construction control (quality control) and standard test methods are listed; and the book is supplemented by a series of appendices which detail useful tables, references, and analytical methods. Although much of the content is based on the practical experience of the Authors' in the Australasian environment, a specific chapter is included on stabilization in extreme conditions (i.e. low temperatures, high rainfall, etc.). Much hitherto unpublished data as well as published research from all parts of the world is critically reviewed and included.
