- The PReSBOX produces a prismatic speciment with nominal dimensions of 4510 mm (lenght) x 150 mm (width) x 120 to 185 mm (height)
- Asphalt prisms prepared in the PReSBOX compactor can be sawn or cored to produce 4-6 prismatic beams or 1-4 cylindrical specimens
- The PReSBOX can be operated by a single person
- Produces specimens with excellent air void distribtion and particle orientation
- Designed for an easy unlocking of the compaction mould, facilitating an effortless speciment extraction at safe height, handling and user safety
