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

SIGNIFICANCE AND USE
In order to determine the characteristics of the asphalt in an asphalt paving mixture, it is necessary to extract the asphalt from the aggregate by means of a suitable solvent and then to recover the asphalt from the solvent without significantly changing the asphalt's properties. The asphalt recovered from the solvent by this practice can be tested using the same methods as for the original asphalt cement, 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 Standard Practice are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice alone does not completely assure reliable results. Reliable results depend on many factors; following the suggestions of Practice or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
SCOPE
1.1 This practice is intended to recover asphalt from a solvent using the rotary evaporator to ensure that changes in the asphalt properties during the recovery process are minimized.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.2.1 Residual pressure measurements are shown in both the SI unit of kPa and the commonly used non-standard equivalent unit of “mm of Hg”.
1.2.2 Measurements of volume and mass are only given in SI units because they are the only units typically used in practice when performing this standard practice.
1.3 This standard 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 standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Summary of Practice
3.1 The solution of solvent and asphalt from a prior extraction is distilled by partially immersing the rotating distillation flask
of the rotary evaporator in a heated oil bath while the solution is subjected to a partial vacuum and a flow of nitrogen gas or carbon
dioxide gas. The recovered asphalt can then be subjected to testing as required.

the asphalt’s properties. The asphalt recovered from the solvent by this practice can be tested using the same methods as for the
