  • Nuclear radiation apparatus and method for dynamically measuring density of test materials during compaction
    Patent number: 4979197
    Abstract: The present invention provides an apparatus and method for dynamically measuring the density of soil, asphaltic material and the like during the compaction of the material. The gauge includes a nuclear radiation source and a nuclear radiation detector means which are mounted in spaced relation from the surface of the test material to form an air gap therebetween. The gauge also includes means for measuring the size of the air gap between the test material and the source and detector system, and means to compensate for the effect of the size of the air gap to thereby obtain the density of the test material.
