Description / Abstract:
This standard describes a procedure for the extraction and
recovery of asphalt binder from asphalt mixtures [both hot mix
asphalt (HMA) and reclaimed asphalt pavement (RAP)] that have a
minimal effect on the physical and chemical properties of the
asphalt binder recovered. This standard is intended for use when
the physical or chemical properties, or both, of the recovered
asphalt binder 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 or other
aggregate testing.
This method is applicable to HMA sampled from the pavement, RAP
sampled from the pavement or stockpile, HMA plant production, or
laboratory fabricated HMA.
This procedure may involve hazardous materials, operations,
and equipment. This procedure 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 procedure to establish
appropriate safety and health practices and determine the
applicability of regulatory limitations prior to use.
