Rotary Evaporator for Binder Recovery


The apparatus is used for the recovery of soluble bitumen from bituminous pavement materials in a form suitable for further testing.
During operation, the solution of solvent and asphalt (bitumen) from a prior extraction is distilled by partially immersing the rotating distillation flask of the rotary evaporator apparatus, in a heating oil bath while the solution is subjected to high vacuum with fine regulation of pressure (up to ±0.1 kPa) according to EN 12697-3 or to partial vacuum and flow of nitrogen gas according to ASTM D5404 and AASHTO TP2. The recovered asphalt (bitumen) can then be subjected to further testing as required.
For the test sets conforming to EN and ASTM versions, see accessories.
