Book Description
Sources of error that have been identified on the gamma-ray soil density gauge are: (1) sensitivity to local density variations, especially at the soil surface, (2) sensitivity to soil composition, and (3) inaccurate calibration techniques. An attempt was made to solve these problems by developing for each gauge calibration models that enable stable and homogenous non-soil standards to be used for calibration. Calibration standards and calibration models for each gauge were found and tested. In the process of developing and testing the new nuclear gauge calibration model, the dual-gauge principal of compensating these gauges for variations in soil composition was discovered. The air-gap method of using this principal is explained and was optimized by using the calibration model developed in the current study.

Book Description
Data is provided from an evaluation of the accuracy of the nuclear gages in comparison with the currently used non- nuclear methods of determining soil density and moisture content. The research study was principally theoretical in nature and was conducted in two parts with each part respectively considering density and moisture content. Two existing commercial gages were evaluated, and a nominal experimental program employing non-soil standards of known density and composition was conducted to verify the density results. The results of the moisture content study were checked against data in the literature.

Book Description
Annotation Presents 22 papers, from the July 1999 symposium, written on the use of various standardized methods for specifying and controlling the compaction of soil for engineered constructed earth fills. Perspectives include the historical background, current state-of-the- art practices, case histories of challenging situations, concerns regarding appropriate design parameters for compaction control, and new methods to evaluate soil compaction and related qualities.
