Main Features

  • PReSBOX® produces a prismatic specimen with nominal dimensions of 450 mm (length) 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.
  • A single person is needed to operate PReSBOX®
  • Produces specimens with excellent air void distribution and particle orientation
  • Designed for an easy unlocking of the compaction mould, facilitating an effortless specimen extraction at safe height, handling and user safety.

Description

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 volumetric properties, giving an exceptional measure of workability.

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.

It also 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.
