ASTM D 2172,
AASHTO T 164
Used for quatitative
determination of
bitumen and aggregate
cement, as well
as aggregate
gradiation of bituminous
paving materials.
Mass and moisture
content of specimen is
first determined.
Specimen is heated to
induce crumbling, then
placed in rotor bowl.
Solvent is added and
centrifuge is started and continued until all solvent is
forced through paper filter ring on outer rim of bowl. This
process is repeated until the solvent is clear in color,
indicating bitumen extraction is complete.
Aggregates are then weighed and graded and mineral
content of extract determined.
Centrifuge is made of
lightweight cast aluminum
and treated for
corrosion resistance.
Comes complete with
aluminum bowl, cover
and 25 filter rings.
Electric models are
equipped with positive
speed adjustment; also
available in explosion
proof design. Manual
models are ideal for
field use - no electrical
power needed.

Biodegradable Solvent
Approved by state DOTs for centrifugal and vacuum
asphalt extraction tests. This solvent is accepted as a
biodegradable, ozone-friendly alternative to chlorinated
solvents. Not for reflux extraction or other heated
solvent methods.
