Binder Recovery Apparatus
EN 12697-3 | ASTM D5404 | AASHTO TP2 | EN 12607-3 | EN 12697-1 | ASTM D1856 | CNR 133 | AASHTO T170 | AASHTO R59
Rotary evaporator for binder recovery 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. 75-PV1650: Rotary evaporation apparatus. 230 V, 50-60 Hz, 1 ph
The Rotary evaporator can accept evaporating balloons up to 5000 m cap. For the test sets conforming to EN and ASTM versions, appropriate accessories available. |
Binder recovery apparatus by vacuum is used to remove the solvent from the binder/solvent solution in order to determine directly the total content binder in the aggregate/binder mixtures.
75-B0025/B: Binder recovery apparatus, vacuum pump method. 230 V, 50-60 Hz, 1 ph The apparatus consists of a power operated vacuum pump, fit with vacuum regulator, producing a vacuum down to 200 mbar, a thermostatically controlled water bath, and two flat-bottomed flasks 250 ml capacity with rubber bungs and connections. All necessary fittings and connections complete the set. |
Binder recovery apparatus by Abson method is used for recovering the asphalt (bitumen) from a solution of a previous extraction.
The asphalt is recovered with properties substantially the same as those it possessed in the bituminous mixture and in quantities sufficient for further testing. 75-B0026: Distillation assembly for recovery of binder from solution by Abson method. 230 V, 50-60 Hz, 1 ph The apparatus consists of a distillation assembly including: Extraction flasks, Glass tubing, Inlet aeration tube, Electric heating mantle, Water-Jacketed condenser, Thermometer, Gas flowmeter, Stands and clamps. |
