Dry Density & Moisture Content

Product

Compaction control in the field can be achieved by determining the moisture content and maximum dry density.  A rapid estimate of the moisture content in the field can be obtained by plotting curves in the laboratory, showing the relationship between moisture content versus density and penetration resistance, using proctor needles, while conducting the standard compaction test.

LM17225: PROCTOR  PENETROMETER (SPRING TYPE)

The spring penetrometer consists of a housing, a plunger calibrated to 40 kg. x 1 kg., a long stem graduated at 12.5 mm. intervals, for use with large sectional area needles, a small stem for use with smaller needles and a set of 8 needles having the following face areas  :  6, 5, 3, 2, 1.5, 1, 0.5, 0.25 cm . Complete in a wooden carrying box.

LM17226  : PROCTOR   PENETROMETER  (HYDRAULIC TYPE)

Similar to LM17225, but the spring system is replaced by a hydraulic system and the penetration load can be read directly from the calibrated gauge.  Greater sensitivity of penetration control is possible with this unit.
