Revision of D7906-14 Standard Practice for Recovery of Asphalt from Solution Using Toluene and the Rotary Evaporator

Keywords

None Provided

Rationale

Remove ambiguity from section 10.2.1 where is says Hold or release vacuum if foaming or bubbling occurs. When foaming subsides, apply maximum vacuum. While it is assumed that maximum vacuum means apply a vacuum of 6.7 +/- 0.7 kPa, however this may be misunderstood to mean to apply total vacuum of 0 kPa. Update to thermometer equipment requirements. Update title to change Asphalt to Asphalt Binder
