ABSTRACT:
A method and apparatus for determining the approximate optimum moisture content required to facilitate compaction of earthy and/or granular material wherein a sample of the material to be compacted is subjected to compressive force while contained within a container and then removed therefrom and examined for behavior characteristics which give indication of its existant moisture content relative to the optimum requirement for best compaction of the sampled material.
