Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted of the potential applicability of nuclear measuring techniques for determining soil density and moisture content at depth, and changes in these properties, for Navy civil engineering purposes. Measurements were obtained under two different types of engineering requirement to assess measurement capabilities: (1) in base material and subgrade soil beneath the pavements at five airfields, to detect long term variations; (2) in hydraulically placed foundation soils at two construction sites, both before and after densification of the soil was attempted by driving compaction piles, to detect changes due to the densification effort. The data were analyzed and statistical procedures were developed to determine the magnitudes of measurement error. Measurement errors were relatively low compared with the measured temporal variations in the soil properties at th soil densification sites, but were so large as to obscure a large portion of low-level, long-term changes occurring in the pavement subgrades.

Download or read book Optimization of Density and Moisture Content Measurements by Nuclear Methods written by Robin P. Gardner and published by Highway Research Board. This book was released on 1971 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective was to minimize the errors identified with measurement of density and moisture content of soils using nuclear gauges. To provide a reasonable basis for optimization, all identified errors were combined to yield a single criterion, the quality factor, which can be used to evaluate the over-all performance of a nuclear density gauge. Research aimed at minimizing moisture content measurement errors involved using the Monte Carlo or random walk method to simulate gauge response, checking the results of the simulation against experimental studies, and attempting to generalize the Monte Carlo results.
