COMPARISON OF SOIL DENSITY AND WATER CONTENT DETERMINATIONS WITH CONVENTIONAL AND NUCLEAR EQUIPMENT

Compaction control of earth fills and grades is based on density and water-content measurements at the site of the work. To assist in appraising the relative usefulness of both conventional and nuclear equipment this report presents the results of an investigation in which their performance and economics are compared. Eight practical locations in the Toronto Ontario area were chosen for testing. Four sites were in various till soils and four in other soil types used for fill. At each location between three and six complete tests were run within a distance of a few feet. Each test was planned to measure soil density and water content with all three types of equipment under as identical conditions as possible. Results of this investigation of interest to railway engineers concerned with earth fill operations were summarized as follows: (1) Control measurements of soil density and water content can be made by conventional tests or by relatively new nuclear equipment. (2) The nuclear method of test has the advantage of giving final test results on the site.
