Book excerpt: This study was an extension of earlier work by Sherwood and Noble to determine the nature of the clay content of common Virginia soils and the strength development of those soils in cement mixtures. In addition attempts were made (1) to study the relationship between parent materials and their derived soils, (2) to determine any changes in physical and chemical properties down the soil profiles, (3) to study the reactions accompanying cement stabilization of soils, and (4) to determine the soil factors influencing strength development in soil-cement mixtures. The three types of soil chosen for the study were (1) a limestone derived silty clay, (2) a basic intrusive residuum, and (3) a resilient micaceous soil. Samples were subjected to chemical, X-ray, microscopic, and engineering analyses. Results showed that the presence of large amounts of clay in the soil-cement specimens appeared more important than the type of clay in determining short-term strength development.

Available in PDF, EPUB and Kindle. Book excerpt: The results are presented of a laboratory study on the cement stabilization of three commonly encountered Virginia soils. The report presents the results of an extensive study of the physical, chemical and mineralogical properties of the three soils. The reaction between the three soils and Portland cement was monitored using unconfined compressive strength, x-ray diffraction, petrographic microscope observations and chemical analysis of acid and water leachates from soil-cement pastes. Some of the conclusions developed by the author are as follows: (1) when the major clay minerals are considered montmorillonitic soils suffered the greatest deterioration from cement treatment, kaolinitic soils less and illitic soils least, (2) iron in the iredell soil appeared to react or dissolve readily with cement, (3) the amount of clay present rather than the type of clay appeared to affect the short term strength development, and (4) three mechanisms responsible for reaction of soil and deterioration of soil constituents are offered. These mechanisms are: (a) calcium hydroxide from hydrated cement reacts with clay minerals or amorphous material yielding calcium compounds of silica, alumina and iron; (b) silica, alumina and iron dissolved from soil constituents react with calcium hydroxide forming calcium compounds; and (c) silica, alumina and iron dissolved from soil are physically adsorbed onto partially hydrated cement grains.

Available in PDF, EPUB and Kindle. Book excerpt: A growing population and increasing urbanization over the past century have made it difficult to locate suitable ground for siting infrastructures in densely populated areas. The Deep Mixing Method (DMM) was developed and put into practice in Japan in 1975 to cope with the headaches of stability and/or excessive settlement in soft soil areas. This method involves using cement and/or lime as a soil stabilizer, added in-situ to deep soils, and has now been adopted not only in Japan but in the USA and other parts of the world as well. This book presents properties of this treated soil method, its various applications, its design and execution, and accumulated research results over the last twenty-five years.

Available in PDF, EPUB and Kindle. Book excerpt: The pneumatic flow mixing method was developed to stabilize dredged soil and surplus soil for promoting their beneficial use in 1999. The pneumatic flow mixing method is a new type of the ex-situ cement stabilization techniques, in which dredged soil and surplus soil is mixed with a relatively small amount of chemical binder without any mixing paddles and blades in a pipeline. When a relatively large amount of compressed air is injected into the pipeline, soil can be separated into small blocks. When binder is injected into the pipeline, the soil block and binder are thoroughly mixed by means of turbulent flow generated in the soil block during transporting. As this method has many benefits ? rapid and large scale execution can be conducted with low cost ? it has been applied to many land reclamation projects, backfilling behind earth retaining wall projects and shallow stabilization projects using dredged soils and surplus soils. The book presents the state of the art in the pneumatic flow mixing method, and covers recent technologies, research activities and know-how in machinery, design, construction technology and quality control and assurance. The Pneumatic Flow Mixing Method is a useful reference tool for engineers and researchers involved in admixture stabilization technology everywhere, regardless of local soil conditions and a variety in applications.

Book excerpt: Pavements are engineered structures essential to transportation, commerce and trade, and everyday life. In order for them to perform as expected, they must be designed, constructed, maintained, and managed properly. Providing a comprehensive overview of the subject, Pavement Engineering: Principles and Practice, Second Edition covers a wide range of topics in asphalt and concrete pavements, from soil preparation to structural design and construction. This new edition includes updates in all chapters and two new chapters on emerging topics that are becoming universally important: engineering of sustainable pavements and environmental mitigation in transportation projects. It also contains new examples and new figures with more informative schematics as well as helpful photographs. The text describes the significance of standards and examines traffic, drainage, concrete mixes, asphalt binders, distress and performance in concrete and asphalt pavements, and pavement maintenance and rehabilitation. It also contains a chapter on airport pavements and discusses nondestructive tests for pavement engineering using nuclear, deflection-based, electromagnetic, and seismic equipment. The authors explore key concepts and techniques for economic analysis and computing life-cycle cost, instrumentation for acquiring test data, and specialty applications of asphalt and concrete. The Second Edition includes more relevant issues and recently developed techniques and guidelines for practical problems, such as selection of pavement type, effect of vehicle tires, and use of smart sensors in rollers and software for drainage analysis. This book presents in-depth, state-of-the-art knowledge in a range of relevant topics in pavement engineering, with numerous examples and figures and comprehensive references to online resources for literature and software. It provides a good understanding of construction practices essential for new engineers and materials processing and construction needed for solving numerous problems.

Available in PDF, EPUB and Kindle. Book excerpt: More than ten years have passed since the first edition was published. During that period there have been a substantial number of changes in geotechnical engineering, especially in the applications of foundation engineering. As the world population increases, more land is needed and many soil deposits previously deemed unsuitable for residential housing or other construction projects are now being used. Such areas include problematic soil regions, mining subsidence areas, and sanitary landfills. To overcome the problems associated with these natural or man-made soil deposits, new and improved methods of analysis, design, and implementation are needed in foundation construction. As society develops and living standards rise, tall buildings, transportation facilities, and industrial complexes are increasingly being built. Because of the heavy design loads and the complicated environments, the traditional design concepts, construction materials, methods, and equipment also need improvement. Further, recent energy and material shortages have caused additional burdens on the engineering profession and brought about the need to seek alternative or cost-saving methods for foundation design and construction.
