AASHTO Designation:T 319-08 pdf free download

1.1.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.

1.2.This method  is applicable  to HMA  sampled  from the pavement,  RAP  sampled  from  the pavement or stockpile,  HMA  plant  production,   or laboratory   fabricated  HMA.

1.3.This procedure may involve hazardous materials, operations, and equipment.

This procedure does not purport to address all of the safety concerns, ifany, 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.
