The PReSBOX® provides the latest in asphalt speciment preparation and mix evaluation technology. PReSBOX® produces high quality asphalt prisms from which beams and cylinders with excellent air voids distribution, homogeneity and particle orientation can be cut.
The unique shearing action of the PReSBOX® closely replicates the conditions under which asphalt is placed in the field and produces specimens with excellent homogeneity and volumetic properties, giving an exceptional measure of workability.
The PReSBOX® also provides an accurate measure of the workability (relative effort required for compaction) of Hot Mix Asphalt (HMA) needed in the field to achieve a target void content.
The PReSBOX® Shearbox Compactor features a PC interface for user entry of compaction parameters, and provides a real-time graphic display of data, e.g. specimen height, vertical stress and air voids per cycle.
- The PReSBOX produces a prismatic specimen with nominal dimensions of 450 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
