ASPHALT ANALYZER - Ground Tire Rubber Extraction Option

This asphalt analyzer unit model PG is used for the extraction and determination of binder content in rubber modified bituminous mixtures in use with not flammable solvent (Trichloroethylene). 



  • Extraction and distillation is PC controlled and is using Windows® as Software. Every step of the extraction is shown on the large touch panel screen.  

  • Equipped with a second solvent circuit allows the device the extraction of asphalt mixtures as standalone procedure with the washing chamber or the extraction in the vertical standing unit with an automatic decantation system. 

  • Bituminous material will be separated through a continuously mixing and solvent dispensation procedure.  

  • Rubber particles are separated from the asphalt material and swim up to the surface and there they will be collected inside the special collection tray.

  • Aggregates are stored in the washing chamber; filler material is separated in the centrifuge. 

  • Binder and solvent will be divided from each other in the solvent recovery similar to original model. 

  • All parts of your bituminous mixtures are dried during the test procedure. 

  • Machine comes equipped with the special collection tray and the mixing tool.

Washing Machine

Washing machine for cleaning bitumen stained containers, glass flasks etc. using solvent in a closed cycle system. The washing chamber made of stainless steel is equipped with an indirect heating system and spray nozzles.


  • Interchangeable inserts fit up to 6 round bottom flasks or 6 RTFOT test cups can be cleaned simultaneously.

  • ​Sprinkler system and solvent steam are used for the washing process.

  • A vacuum system assists the fast drying of clean parts as well as the solvent distillation.

  • The bottom part of the wash container is equipped with a valve to remove the bitumen into an evaporator flask whilst the solvent is recovered in the clean solvent tank.

  • The process is computer controlled.

  • Variable run-times are possible.

  • Usual run-time approx. 30 – 45 minutes.
