ASTM D 4253, D 4254
 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. Maximum density is
determined by placing soil in special molds and densifying using
a vertically vibrating table and surcharge. Minimum index density
is determined by loose placement in the molds, using special
pouring funnels, scoop, or shovel, depending on size of soil
particles.
Semi-noiseless Vibratory Table has a cushioned steel 30 x 30" (762
x 762 mm) vibrating deck activated by electromagnetic vibrator
with over 100 lb (45.5 kg) actuator. The table has 750 lbs (341
kg) load capacity and requires 800 watts, 12 amps at 230 V. Table
height is 21" (533 mm). Vibration rate is 3600 VPM (3000 @
50 Hz) and amplitude adjusts in accordance with ASTM requirements.
The solid state circuitry allows precise amplitude control even
with fluctuating voltage supplies.
Cylindrical metal unit weight Mold Sets for 0.1 and 0.5ft3 (2.83
and 14.2 liters) capacity have attached carrying handles and guide
brackets for the Gauge Set. They come complete with detachable
guide sleeve with clamp assembly, surcharge base plate with removable
handle, and surcharge weight and handle. Mold included with Set
is 6.000" (152.4 mm)
ID x 6.112" (155.2 mm) IH; surcharge weight plus base plate has 56. 5
+ 0.5 lb (25.5 + 0.2 kg) total weight. Larger mold with Set is 11.000 (279.4
mm) ID x 9.092" (230.9 mm) IH with 190 + 2 lb (86.2 + 0.9 kg) total weight
of base plate with surcharge weight. Model Gauge Set fits guide brackets of
either Mold Set to measure distance from top of mold to top of base plate after
densification (to compute volume change). Set includes a 2" (50.8 mm)
Dial Indicator, travel is 0.001" (0.025 mm), and also a special holder
to fit molds. A metal 3 x 12 x 1/8" (76 x 305 x 3.2 mm) calibration bar
is also included.
Accessory Pouring Funnel Set Model is required for loose placement
of 3/8" (9.5 mm) and finer soil. Set includes two 6" (152
mm) diameter x 12" (305 mm) long metal cylinders, each with
funnel and 6" (152 mm) long delivery spout attached to one
end. Spouts are 1" (25.4 mm) and 1/2" (12.7 mm) in diameter.
