ASC – Asphalt Shear box Compactor

Asphalt technologists are acutely aware of the importance of a representative specimen during any laboratory performance testing.
The precise shearing motion of the ASC replicates the conditions of field compaction in order to reproduce the field properties of asphalt,
quickly and easily under the controlled conditions of a laboratory.
The ASC compacts large asphalt prisms that can be sawn to produce four to six beams or slabs for laboratory wheel tracking; or the prism
can be cored to produce three to four 100mm diameter cylinders, all having essentially identical properties.
The electronic control unit with touch screen color display operates
like a standard Windows based PC for the management and
analysis of the data, test results and graphs.
The user friendly touch-screen icon interface allows for easy
set up parameter entry, enables immediate (fully automatic test
generation.
A LAN connection to Intranet/Internet enables remote
communication to receive immediate diagnostic
analysis and technical support from Matest
technicians, and/or software updates.
During the compaction process a lateral displacement is applied to the specimen along with a vertical load, which results in a shearing
action that makes the compaction similar to the the on-field one.

Specimen is extruded after the machine has completed the specified number of cycles,
or when the required specimen height has been reached.
An automatic extruder allows an easy extraction of the compacted specimen.
