ASTM D7906-22 PDF Download

ASTM D7906-22 is a standard practice that outlines the procedure for recovering asphalt binder from a solution using toluene and a rotary evaporator. The scope of this practice is to minimize any changes in the properties of the asphalt binder during the recovery process. By using a rotary evaporator, asphalt binder can be efficiently separated from the solvent, ensuring that the original properties of the binder are preserved. This standard practice is useful for asphalt testing and research purposes, where it is necessary to separate the asphalt binder from a solution in a controlled manner.
