Determination Of Field Density Test Of Soil By Core
Core cutter method of field density test is conducted in the field to know whether the specified compaction is achieved or not.In certain cases, it is necessary to determine the density of soil either as it exists naturally in the ground or as it may be compacted in the fill.In the former case, this density of soil in place may be used to estimate the comparative strength of the soil.
