In this method of determining the dry density of in-situ soil, a Core Cutter of known volume is driven into the soil by means of a Rammer.
The Core Cutter is removed, trimmed and the soil obtained is weighed and dried for a moisture or density check.
The apparatus consists of a Core Cutter which is a steel tube 100 mm inside diameter by 130 mm long, a Driving Dolly recessed to fit the core cutter, and a Rammer that comprises a steel rod, handle and base.
