In soil testing for civil construction, Field Density testing would be amongst the most common. Its purpose is to determine the Field Dry Density (in t/m3) and Moisture Content (as a %) of the material being tested. The Field Dry Density is usually compared with a laboratory compaction test of the same soil type, to produce a ratio between field and laboratory compaction.
Compaction testing as carried out in a soil testing laboratory is done to determine the Maximum Dry Density (t/m3) and the moisture content at which that is achieved known as the Optimum Moisture Content (%).
This data is used to compare to the Field Dry Density (see Field Densities above) to determine the Density Ratio and Moisture Variation.
Compactions are either performed as Standard or Modified and sometimes Oversized if the material being tested is of a larger particle size (rock).
Test items of Civil Engineering class:
1. soil test (screening, density, water content, liquid and plastic limit, compaction, particle analysis sieve);
2, aggregate, stone (screening, depending on ...
