ASTM D5404/D5404M-12 (R2017) is a standard practice that outlines the procedure for recovering asphalt from a solvent using a rotary evaporator. The purpose of this practice is to extract the asphalt from an asphalt paving mixture in order to determine its characteristics and compare them to the original asphalt cement.

The practice emphasizes the need to minimize changes in the asphalt properties during the recovery process. It provides guidelines on the equipment, solvent, and procedure to be followed to achieve reliable and consistent results.

The standard also includes notes and cautions regarding the competency of personnel and the calibration and maintenance of equipment, as these factors can impact the quality of the results obtained. It highlights the importance of following specifications and guidelines, such as Specification D3666, to ensure reliable testing, sampling, and inspection.
