Binder and Solvent Recovery

75-PV1650

Binder recovery allows to collect a sample of binder separated from the mix by solvent extraction. Thanks to the controlled atmosphere (vacuum or neutral gas) the binder is not oxidized by the process and can be used for binder tests. Most common binder recovery systems are the rotary evaporator and Abson method. Solvent can also be recycled by distillation and be reused for further binder extractions.

Binder Recovery Apparatus by Abson Method

Used for recovering the asphalt (bitumen) from a solution of a previous extraction.

Standards ASTM D1856 CNR 133 AASHTO T170 AASHTO R59

Binder Recovery Apparatus by Vacuum

Used to remove the solvent from the binder/solvent solution.

Standards EN 12697-1

75-B0025/B
Description
 
Used to remove the solvent from the binder/solvent solution in order to determine directly the total content binder in the aggregate/binder mixtures. 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. The water bath can also be used for other applications as for example for the Marshall test. For more information see Water baths, model 76-B0066/A. For more information on the Vacuum pump, see Vacuum pumps, model 86-D2001 with vacuum gauge regulator 86-D2004/5.

Rotary Evaporator for Binder Recovery

The apparatus is used for the recovery of soluble bitumen from bituminous pavement materials.

Standards EN 12697-3 ASTM D5404 AASHTO TP2 EN 12607-3

75-PV1650
Description
 
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.

Solvent Recovery Unit

Used to recover the solvent liquid after its use for the extraction tests.

75-B0027/A
Description
 
Used to recover the solvent liquid after its use for the extraction tests. This unit has been designed to recover non-flammable solvents and consists of two stainless steel chambers, one for dirty solvent and the other for the cleaned solvent. An electric heater in the left-hand chamber distils the solvent, which then passes through a water cooling system and drops into the second chamber ready for re-use in a new test. Once the process is completed, a temperature switch automatically stops the heating elements. Supplied complete with 10 m plastic tube, tube clamps, sieve insert 0.6 mm opening and one lid. Particularly useful to recover solvent used with the paper filter extractor, wire mesh extractor, Kumagawa extractor, reflux extractor and filterless centrifuge binder extractors.
  • Max. temperature: 150°C
