• Abstract:
  The research objectives of this project were to investigate a new ; method of in-place determination of soils densities and moisture levels ; employing a nuclear physics principle of the gamma radiation function as ; the measurement technique, with specific emphasis upon: ; a. The exploration and definition of the range of measurements which might be established as a uniform standard ; for calibration of the nuclear measuring device; and ; b. An evaluation of the functional adaptation and utility ; of the device along with an appraisal of the reliability ; of the measurements produced. ; Other areas of particular interest to be observed during the project ; were identified as follows: Time requirements per test, optimum probe depth, weather and/or temperature effects on test results, and undesirable aspects.
