Density Drive Sampler



The Density Drive Sampler is used to determine the in-place density of soil by driving a thin-walled tube to obtain a soil sample of known volume.


The Sampler consists of a zinc plated steel drive head and sliding 10 lb hammer. The drive head is provided with a shock spring. Drive tubes are zinc plated.

Drive Tubes are available in two sizes:

  • 3 in x 2.75 in (0.01 ft3)
  • 4 in x 5 in (0.033 ft3)

Applicable Standards

ASTM D 2937, AASHTO T 204

Note: Because of the difficulty sometimes encountered with sample removal from the tube, swaged end tubes are not recommended in stiff soils.
