Technical Specifications
The Asphalt Prism Shear Box Compactor provides the latest in asphalt specimen preparation and mix evaluation technology. The unique shearing action of the Asphalt Prism Shear Box Compactor 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. Asphalt Prism Shear Box Compactor produces high quality asphalt prisms from which beams and cylinders with excellent air voids distribution, homogeneity and particle orientation can be cut.
The Asphalt Prism Shear box 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 Asphalt Prism Shear Box Compactor 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.
