Feature:
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
