Description / Abstract:
These methods cover the quantitative determination of asphalt
binder in hot mix asphalt (HMA) and HMA pavement samples. Aggregate
obtained by these methods may be used for sieve analysis using T
30.
The values stated in SI units are to be regarded as the
standard.
This standard may involve hazardous materials, operations,
and equipment. This standard does not purport to address all of the
safety concerns 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. Specific hazards are given in
Section 8.
Note 1—The results obtained by these methods
may be affected by the age of the material tested, with older
samples tending to yield slightly lower asphalt binder contents.
Best quantitative results are obtained when the test is made on HMA
mixtures and pavements shortly after their preparation. It is
difficult to remove all the asphalt binder when some aggregates are
used; some solvent may remain within the mineral matter affecting
the measured asphalt binder content.
