Centrifuge Extractor (Hand Operated)
ASTM D2172, AASHTO T-58, T-164.
The Instrument is used for determination and checking of Bitumen percentage in Bituminous mix, the mix is added with a solvent and dissolved bitumen is removed by centrifugal action. Consists of a removable Aluminum rotor bowl, Capacity 1500 gms. With a cap and tightening nut. The bowl assembly is mounted on a vertical shaft, which protrudes from a cast housing. This shaft and thus the bowl is rotated fast manually by enclosed gears in the cast body and handle. Solvent is introduced during the test through the holes in the cap of the housing. A drain is provided to collect dissolved Bitumen coming out of the rotating bowl and getting collected in the housing.
CENTRIFUGE EXTRACTOR (BINDER EXTRACTION)
HT-726
Reference Standards: ASTM D2172, AASHTO T164
The Centrifuge Extractor is used to determine the binder (bitumen) content in asphalt mixtures by separating it from aggregates using a solvent extraction process combined with centrifugal force.
The asphalt sample is placed inside a rotating bowl, and a solvent is added to dissolve the bitumen. As the bowl rotates at high speed, centrifugal force separates the dissolved binder from the aggregate. The extracted solution is collected and measured to determine the binder content.
This test is critical for mix design verification, quality control, and compliance with road construction specifications.
