How well do you know nuclear density gauges?
Nuclear density gauges are often the preferred method for testing the moisture and density of compacted soils – particularly those with a high clay content. Like some other field equipment, nuclear density gauges oftentimes are perceived as “plug-and-play” equipment – a misunderstanding that can lead to all sorts of problems in the field and beyond.
There are many variables that can influence a test and knowing these is not only often the difference between passing and failing test results but also whether the results are truly representative of the post-compaction condition of the soil.
