3440 Surface Moisture-Density Gauge
The Model 3440 gives you the features you need for
compaction control, but its enhanced capabilities make it a
step above our basic Model 3430. The Model 3440 is used to
measure the density of asphalt, soil, aggregate or concrete
and the moisture of soil or aggregate. Density can be
measured in either the backscatter or direct transmission
mode and moisture is measured in the backscatter mode. The
backscatter mode is ideal for concrete and hot asphalt,
while direct transmission is the choice for
50 - 300 mm (2 -
12 inch) lifts of soil and aggregates. Test results in as
little as 1 minute allow additional compactive effort to be
applied immediately if necessary.
The Model 3440 and all other gauges in the 3400 series
have replaced conventional density test methods and have
become the industry standard. It also meets ASTM Standard
Test Methods D-6938 (which replaced ASTM D-2922 and ASTM
D-3017 as of November 2006), D-2950, C-1040 and AASHTO
T-310.
