This unique volume explores the use of various standardized methods for specifying and controlling the compaction of soils for engineered constructed earth fills. Topics address the historical background, current state-of-the-art practices, case histories of challenging situations, new concerns regarding appropriate design parameters for compaction control, and new methods to evaluate soil compaction and other related qualities. Also included is a paper on the history of the development and use of the nuclear gauge in the quality control of constructed earth fills. The nuclear gauge has had the single largest impact of any technology in the last 30 years in the field of compaction control. Many of the papers in included in this volume use the nuclear gauge as the basis for comparison of the results of field density and water content measurements. 21 papers divided into 3 sections examine: • Compaction Control Technology and Comparison of Current Methods • Applications and Lessons Learned in the Field • Soil Liner Construction and New Compaction Technology For Geotechnical, Civil, and Construction Engineers
