Asphalt Shear Compactor
Quickly and easily replicates the conditions of field compaction.
ASTM D7981
Asphalt engineers know the importance of a representative sample 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 sawed 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 execution), data acquisition/processing and test report and data file generation.
A LAN connection to Intranet/Internet enables remote communication; to receive immediate diagnostic analysis and technical support from factory trained technicians, and/or software updates.
