4.1 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. 4.2 Users are cautioned that the recovered binder properties from an asphalt mixture sample may not exactly represent the properties of the original asphalt binder due to factors outside of laboratory control such as aging, contamination, and molecular changes caused by exposure to heat and solvents. Consequently, recovered asphalt binder properties should not be used as a basis for acceptance. 1.1 This practice is intended to be
used 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 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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. |
