Now the simplest, fastest way to extrude your gyratory or Marshall specimen is available from Troxler. No electricity or hydraulics needed — the force of gravity and pressing down can extrude any specimen.

The Troxler Gravity Asphalt Specimen Extruder™ is designed to extrude specimens quickly, as fast as you can press down on the mold flange or delayed over any time needed to allow the specimen to cool. Extrude one quarter, one third, one half, or any portion of the specimen to allow for maximum cooling.

The Gravity Extruder works with any brand of gyratory compactor. Now you can use your compactor for what it was intended for — compacting specimens. Be more efficient by using the Troxler Gravity Extruder to extrude the last gyro specimen while you compact the next one.


The gravity extruder offers the following benefits:

  • Extrude 150 mm or 100 mm gyratory specimens
  • Extrude 4" or 6" Marshall specimens
  • Use the adjustable locking plate to extrude any portion of a specimen
  • Then lower the plate and extrude more as desired
  • Lightweight with a very small footprint to fit on any work surface
