SOIL TESTING
LABORATORY AND ON SITE
PLASTIC LIMIT APPARATUS
The plastic limit is the water content at which a soil-water paste changes from a semisolid to a plastic consistency
LIQUID LIMIT DEVICE
Hand or Motorized
Consistency of soil on site
CONE PENETROMETER SOIL
Used to determine geotechnical properties of soils
DYNAMIC CONE PENETROMETER (DCP)
Used to determine underlying soil strength
SHRINKAGE LIMIT APPARATUS
The shrinkage limit (SL) is the water content where further loss of moisture will not result in any more volume reduction
