Soil Density
Sand Cone Apparatus
The Sand Cone Apparatus is used to determine the in-place density
of any soil that can be excavated to a stable condition with hand
tools. This method is generally limited to materials with a maximum
particle size of 2 in (5.1 cm). More >>

Ballon Density Apparatus
The balloon density apparatus determines the in-place density
of soil using a volume displacement method, similar to the sand
cone density method. More >> |

DCP Dynamic Cone Penetrometer
The original Dynamic Cone Penetrometer (DCP) was developed in
1959 by the late Professor George F. Sowers for determining soil
density. The DCP uses a 15 lb (6.8 kg) steel mass falling 20 in
(50.8 cm)
that
strikes
the
anvil to cause penetration of a 1.5 in (3.8 cm) diameter cone (45° vertex
angle) that has been seated in the bottom of a hand augered hole. More >> |

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. More >> |

Realtive Density Apparatus
Apparatus is used to determine the relative density of free-draining
soils. (Soils of this type normally do not respond well to conventional
Proctor moisture-density compaction tests.) More >> |
