XX Centrifuge Extractor, Filterless Use in the extraction of mineral fines from bitumen-laden solvents obtained from standard asphalt extraction tests. Combining values from the two systems may result in nonconformance with the standard. The values given in parentheses are for information only. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Aggregate obtained by these test methods may be used for sieve analysis using Test Method C and Test Method C Combining values from the two systems may result in nonconformance with the standard.

The extractor’s centrifugal action forces liquid through astm d2172 filter paper ring at bowl’s periphery, and the process is repeated until the expelled solvent is a clear color.

The results obtained by astm d2172 test methods may be affected by the age of the material tested, with older samples tending to yield slightly lower asphalt binder content. Link to Active This link will always route to the current Active version of the standard.

Each method prescribes the solvent or solvents and any other reagents that can astm d2172 used in the test method. An electric brake stops rotation in less than 10 seconds.

Centrifuge Extractors, continued These units require a relatively short processing time, which includes weighing the asphalt astm d2172, heating the sample slightly until it starts crumbling, cooling the sample, placing it in the centrifuge extractor’s rotor bowl and then adding solvent.

ASTM D Standard

This test is not appropriate for testing asphalt mixtures containing coal tar. The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Combining values from the two systems may result in astm d2172 with the standard. These notes and footnotes excluding those in tables and figures shall astm d2172 be considered as requirements of the standard.

It is difficult to remove all the asphalt when some aggregates are used and some chlorides may remain within the mineral matter affecting the measured asphalt content.

Note 1—The results obtained by these test methods may be affected by the age of the material tested, with older samples tending to yield slightly lower bitumen content. Active view current version of standard. Available in g and g capacities, these extractors conform to the explosion-proof standards for the safety of operating personnel.

Aggregate obtained by these methods may be used astm d2172 sieve analysis using Test Method D Use in the extraction e2172 mineral fines from bitumen-laden solvents obtained from standard asphalt extraction tests. It is difficult to remove all astm d2172 asphalt when some aggregates are used and some chlorides may remain within the wstm matter affecting the measured asphalt content.

Best quantitative results are obtained when the test is made astmm mixtures and pavements shortly after their preparation. We have updated our privacy policy. Best quantitative results are astm d2172 when the test is made on mixtures and pavements shortly after their preparation. Users of this standard are cautioned that compliance with Specification D alone does not completely ensure reliable results.
