• Abstract:
  This study was concerned with the quality of recovered asphalt cement which may be attributable to the method used for extraction or to the Abson recovery. Variables of these procedures such as the time an asphalt cement was exposed to extraction solvent, the total quantity of asphalt cement recovered, the total quantity of extraction solvent, and both the type and quantity of fines in the extracted mix samples were isolated to determine their influence on tested asphalt cement properties. Also examined was the testing variation within one operator and between two operators. Findings with respect to the above aims have led to a recommendation that recovery of asphalt from solution by the Abson method (AASHTO T 170-73) should be strictly adhered to, except that the extraction from the aggregate-asphalt mixture should be in accordance only with Method A of AASHTO T 164-76.
