Centrifugal asphalt extractor
for the quantative determination of bitumen content and gradation
of aggregates in bituminous material. Operation requires a relatively
short period of time: Sample is weighed, heated slightly to start
crumbling, cooled, placed in an aluminum rotor bowl and solvent
added. When set in motion, centrifugal forces all liquid through
a filter-paper ring at the periphery of the bowl. The process is
repeated until expelled solvent is clear, aggregates are then weighed
