Standard Practice for Recovery of Asphalt Binder from Solution Using the Rotary Evaporator

Importancia y uso:

4.1 In order to determine the characteristics of the asphalt binder in an asphalt paving mixture, it is necessary to extract the asphalt binder from the aggregate by means of a suitable solvent and then to recover the asphalt binder from the solvent without significantly changing the asphalt binder’s properties. The asphalt binder recovered from the solvent by this practice can be tested using the same methods as for the original asphalt binder, and comparisons between the properties of the original and recovered asphalt can be made.

Note 1: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
