ASTM WK40799

    Work Item: ASTM WK40799 - New Practice for Recovery of Asphalt from Solution Using Toluene and the Rotary Evaporator

    (What is a Work Item?)

    Developed by Subcommittee: D04.25 | Committee D04 | Contact Staff Manager



    1. Scope

    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 UnitsThe 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 nonconformance with the standard. 1.2.1 Residual pressure measurements are shown in both the SI unit of mbar and the commonly used nonstandard equivalent unit of mmHg. 1.2.2 Measurements of volume and mass are only given in the SI units because they are the only units typically used in practice when performing this 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.
