S205N
AUTOMATIC SCB SYSTEM NEW
THE FAST AND SIMPLE WAY TO PERFORM ASPHALT FRACTURE TESTING
STANDARDS: EN 12697-44 | AASHTO TP124 | ASTM D8044
The Automatic SCB system, used in conjunction with the S205N Unitronic 50 kN load frame, is an accurate device for conducting mechanical
testing of asphalt mixtures. It can perform various versions of the Semi-Circular Bend (SCB) test for evaluating the fracture characteristics of
asphalt mixtures at intermediate service temperature conditions. Pavement engineers can use these tests to determine the material characteristics
needed for pavement design, quality control and/or quality assurance purposes.
Our Automatic SCB system is able to operate in load-control and displacement-control modes and can accommodate a wide range of test
accessories in order to run several asphalt performance tests, including IDT/TSR, MARSHALL and DIRECT SHEAR.
In particular, Matest offers accessories for conducting SCB tests according to EN 12697-44, AASHTO TP124 (recommended by University of
Illinois) and ASTM D8044 (recommended by Louisiana State University). The load and displacement parameters measured by the Automatic
SCB system can be used to predict cracking performance of asphalt mixtures based on the Illinois Flexibility Index (I-FIT) and Critical Strain
Energy Release Rate (Jc).
MAIN FEATURES
Precision load cell and LVDT for load and
specimen vertical displacement measurement.
Loading sequence fully automated with
microprocessor control of the loading ram.
Load and displacement measured with 8 analog A/D
inputs.
Touch screen display and intuitive controls allow for
rapidly setting new test parameters and monitoring
test data in real time.
The data acquisition system can connect to multiple
transducers simultaneously.
The frame maintains the specimen alignment during
the test.
The durable electromechanical loading system
needs minimal maintenance.
Optional high quality Environmental Chamber
performing tests between -25 °C and + 60 °C.
