A method and an apparatus for testing density of soil using water and a sheet instead of standard sand are provided to rapidly measure the volume of a test hole through a volume measurement scale scored at a cylindrical water bath. An apparatus for testing density of soil using water and a...
Some methods require burdensome logistics or have time requirements that limit their use or the number of tests that can be executed. A test method, similar to the sand-cone method, was developed that uses steel shot as the material to which a volume of soil is compared to calculate soil ...
