TE-BBR Pro Thermoelectric Bending Beam Rheometer

ASTM D6648 and AASHTO T313 - For Asphalt Binder Research, Mix Design, Forensic Studies and Repeated Stress and Creep Recovery

The TE-BBR Pro is the only programmable, bending beam rheometer that allows high loads, up to 44 N, to be applied under truly controlled stress rates for asphalt binder research, mix design, forensic studies and repeated stress and creep recovery testing. Bath temperature is thermoelectrically controlled to ‒40 °C. NOTE: This instrument is not designed to meet the low end force requirement (0.15 mN) of ASTM D6648 and AASHTO T313 and does not control strain.

Common Applications

  • Asphalt binder research
  • Asphalt mix design
  • Asphalt forensic studies
  • Repeated stress and creep recovery testing

Precise, repeatable results

  • Temperature controlled to −40 °C
  • Force is applied direcly (unlike displacement controlled instruments) for outstanding stress accuracy and control
  • 1 year warranty included with instrument purchase

Versatile test design options

  • Adjustable span lengths (100 mm, 120 mm, 140 mm and 160 mm) and sample thickness (6.35 mm to 12.7 mm)
  • Capable of measuring specifmen beam loads from 0 g to 4.5 kg
  • Specimen beam deflection capacity from −2.5 mm to 7.5 mm with resolution to 0.15 µm (1550 Å)
  • Maximum force capacity of 44 N (4.5 kg) in any repeated cycle with resolution to within 1.4 mN (0.14 g)
  • Totally programmable stress rates, stress profiles and test periods
  • Loading rate can be trapezoidal or square waves with 1/4 second resolution
  • Pneumatic pressure regulators allow the operator to adjust pressure on main input line, air bearing and shaft load

Automated operation and reporting

  • Simple to use, Windows-based operational software (included) controls the entire testing and provides a graphical display of stress and strain
  • Acquired data is automatically stored for off-line analysis
  • RS-232 interface easily transfers data and exports reports/graphs to any Windows®-compatible printer (USB to RS-232 adapter available)
  • Loading and unloading profiles can be constructed for many cycles

Compact, environmentally friendly design

  • TE-cooled with solid-state Peltier element. Requires no external refrigeration (e.g. compressors). A separate air-water heat exchanger removes heat from the Peltier cooling devices.
  • An integrated, self-contained bath cools using methanol or ethanol as the bath medium. No pressurized, costly or hazardous refrigerants are required.
