InstroTek's Auto_SCBTM is a precise and versatile device specifically designed for testing fracture characteristics of asphalt mixtures. You can now conduct mechanical testing of asphalt mixtures automatically and accurately.

Auto_SCB helps predict the cracking potential, ductility and performance of asphalt mixtures. With the balanced mix design approach, pavement designers and maintenance practitioners can run various versions of Semi-Circular Bend (SCB) test at a fraction of the cost of servo-hydraulic systems. Auto_SCB is capable of operating in load-control and displacement-control modes and can accomodate a vast range of test accessories for asphalt performance tests, such as IDT strength and IDT creep compliance.

Asphalt Performance Tests:

  • SCB
  • Marshall
  • Direct Shear on asphalt layers


  • Meets AASHTO TP105, IL (I-Fit) and LSU standards
  • Touch screen display with easy-to-use controls
  • Rapid test parameter settings & monitoring data in real time
  • Operates in load-control and displacement-control modes
  • Capable of connecting to multiple transducers simultaneously
  • Repeatable and accurate test results
