Developed by Subcommittee: D04.25
WITHDRAWN, NO REPLACEMENT
Formerly under the jurisdiction of Committee D04 on Road and Paving Materials, this Test Method was withdrawn in 2010 with no replacement because very few labs have the equipment to run the procedure (and those that do tend to reference the AASHTO procedure T319). There are too few labs to run the required interlaboratory study.
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.
