TE-BBR Thermoelectric Bending Beam Rheometer

ASTM D6648, AASHTO T313, SHRP Binder Provisions
For Low Temperature Flexural Creep Testing of Asphalt Binders

The TE-BBR is a thermoelectrically-cooled bending beam rheometer for testing flexural creep of asphalt binders from ambient to –40 °C (± 0.03 °C). A crack seal option provides for low temperature characterization of crack seal “creep” under load for 0.5” thick specimens. TE-BBR meets or exceeds ASTM, AASHTO and SHRP provisions for flexural creep testing of asphalt binders.

Common Applications

  • Flexural creep of asphalt binders
  • Low temperature characterization of crack seal under load

Precise, repeatable results

  • Meets or exceeds ASTM, AASHTO and SHRP requirement for low temperature flexural creep testing of asphalt binders including ASTM D6648 and AASHTO T313
  • Instrument sample supports feature specimen support strips 3mm ± 0.30 mm in top radius
  • Temperature range: 0 °C to −40 °C. Temperature stability: ± 0.03 °C with resolution to ± 0.01 °C.
  • Resolves specimen beam deflection to 0.155 µm (1550 Å)
  • Resolves force to within 0.147 mN (0.015 g)

Reliable and versatile performance

  • Installed instruments in operation in asphalt testing labs throughout the world
  • Performance verified through ASTM round-robin testing
  • Pneumatic pressure regulators allow operator to adjust pressure on main input line, air bearing and load shaft support
  • Capable of measuring specimen beam loads from 0 g to 450 g
  • Instrument provided with factory-calibration in an ISO 9001-registered laboratory
  • 1 year warranty included with instrument purchase

Simple, automated testing

  • Easy to use Windows-based operational software (included) controls the entire testing process and provides a visual display of stress and strain
  • Simple data transfer via RS-232 interface
  • Reports and graphs can be printed on any Windows®-compatible computer

Compact, self-contained unit

  • TE-cooled with solid-state Peltier elements. Requires no pressurized coolants (a separate air-water heat exchanger is included) and is environmentally friendly.
  • An integrated, self-contained bath cools using methanol or ethanol as the bath medium.
