Scope

1.1 This test method covers a procedure for the extraction and recovery of asphalt binder from asphalt mixtures-both HMA (hot mix asphalt) and RAP (reclaimed/recycled asphalt pavement)—having a minimal effect on the physical properties of the asphalt binder recovered. It is primarily intended for use when the physical properties of the recovered asphalt are to be determined. It can also be used to determine the quantity of asphalt binder in the HMA or RAP. Recovered aggregate may be used for sieve analysis. This may also be accomplished through Test Methods D 2172.

1.2 The values stated in SI units are regarded as the standard. Values in parentheses are for informational use.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

Note 1—It is suggested that agency and personnel performing this test meet the requirements of Specification D 3666.

Significance and Use

This standard is used to extract and recover asphalt binder from an asphalt mixture sample. The recovered mixture components (asphalt binder and aggregates) can then be subjected to further physical tests.
