Application of nuclear densometer to compaction compliance test 2

[Robert168]

Dear Members:

The nuclear densometer is regarded as as a fast and accurate tool to test the density and water content of compacted soils.

For sure it is fast as it takes only 15 seconds to do the measurement. However, is it accurate? If the readings are weird, what might be the cause or causes?

Thanks in advance.

This may be a bit late to include this last piece of information, but the charts which compare the accuracey of the readings against time of readings, are included in some of the 'handbooks' you get when you purchase a new gauge, (at least they were in the UK.
