Cutting Methods. As there are different purposes for taking core samples, which we will discuss shortly, there are different methods for cutting cores. One method of taking a core sample is with a special tool developed by the Cold Regions Research Engineering Laboratory, called a CRREL cutter. This tool consists of a 12" long, 2" diameter ...

Dry density of compacted soil is a measure of the amount of the compaction achieved during the construction. Knowing the field density and field moisture content, the dry density can be calculated. The unit weight of the soil in its field condition is known as field density or in-situ density. The common methods of determination of field density are core cutter, sand replacement, and rubber ...
