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.

These motorized extractors have accurate, dependable electronic solid state speed control; dd2172 speed adjusts up and down. It is difficult to remove xstm the asphalt when some aggregates are used and some chlorides may remain within the mineral matter affecting the measured asphalt astn.

The extractor's centrifugal action forces liquid through a filter paper ring at bowl's periphery, and the process is repeated until the expelled solvent is a clear color. Explosion-proof, motorized units offer the same features along with greater safety. Combining values from the two systems may result in nonconformance with the standard. XX Centrifuge Extractor, Filterless Use in the extraction of mineral fines from bitumen-laden solvents obtained from standard asphalt extraction tests.

Best quantitative results are obtained when the test is made on mixtures and pavements shortly after their preparation. Use in the extraction of mineral fines from bitumen-laden solvents obtained from ast asphalt extraction tests.

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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Best quantitative results are obtained when the test is made on mixtures and pavements shortly after their preparation.

Link to Active This link will always route to the current Active version of the standard. Specific hazards are given in Section 7. Centrifuge Extractors, continued These units require a relatively short processing time, which includes weighing the asphalt sample, heating the sample slightly until it starts crumbling, cooling the sample, placing it in the centrifuge extractor's rotor bowl and then adding solvent. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Each method prescribes the solvent or solvents and any other reagents that can be used in the test method. Aggregate extracted from a paving mixture may be used for sieve analysis using Test Method D 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. Once this is accomplished the remaining aggregates are weighed and graded. Asstm is difficult to remove all the asphalt when some aggregates are used and some chlorides may remain within the d2127 matter affecting the measured asphalt content.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Reliable results depend on many factors; following the suggestions of Specification D or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.

Link to Active This link will always route to the current Active version of the standard. Aggregate obtained by these test methods may be used for sieve analysis using Test Method C and Test Method C An electric brake stops rotation in less than 10 seconds.

ASTM D Standard

Users of this standard are cautioned that compliance with Specification D alone does not completely ensure reliable results. We have updated our privacy policy.

The values given in parentheses are for information only. XX Asphalt Centrifuge Extractor Explosion Proof Available in g and g capacities, these extractors conform to the explosion-proof standards for the safety of operating personnel. The results obtained by these test methods may be asmt by the age of the material tested, with older samples tending to yield slightly lower asphalt binder content.

ASTM D2172

Weight before and after extraction determines constituent proportions. This test is not appropriate for testing asphalt mixtures containing coal tar. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
