Asphalt Prism Shearbox Compactor PReSBOX®

ASTM D7981
IPC Global's PReSBOX® provides the latest in asphalt specimen 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.

77-PV46A02: PReSBOX, Asphalt Prism Shearbox Compactor
220-240 V, 50-60 Hz, 1ph

Main features:
  • 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

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.

Controlling PReSBOX® is IPC Global's Multi Axis Controls System (IMACS). IMACS delivers leading edge performance, unparalleled control and the ultimate in flexible data acquisition.
