Pine GB1 Brovold Superpave Gyratory

Pine Test Equipment, Inc.’s GB1 Brovold Superpave Gyratory Compactor compacts asphalt specimens.

The System

A hydraulic system and an integrated industrial computer drive the GB1. Users define height and number of gyrations using a touchscreen control panel.  Angle of gyration and pressure are fixed.  The GB1 compacts material at a constant pressure and angle of gyration.  It gyrates at a fixed speed.  The system extrudes compacted specimens out the top of the machine.  The enclosed compaction chamber keeps the user safe.   And, two USB ports make exporting data simple.

Specimen Size

The GB1 compacts only 150-mm specimens
