The TE-BBR is a thermoelectrically-cooled bending beam rheometer for testing flexural creep of asphalt binders from ambient to –36 °C (± 0.03 °C). The crack seal option allows low temperature characterization of crack seal “creep” under load for 0.5” thick specimens. Meets or exceeds ASTM, AASHTO and SHRP provisions for flexural creep testing of asphalt binders.

Allows for flexural creep testing of 0.5” thick specimens. Excellent for characterizing crack seal “creep” under load at cold temperatures. Kit includes modified beam support, thin and thick beam for calibration, and all necessary installation hardware and documentation. Support adapter design permits testing of both 0.25” and 0.5” beams.

Product Features

• Controlled by simple to use Windows-based operational software which provides a graphical display of stress and strain
• Environmentally-friendly, solid-state  Peltier cooling technology (no external refrigeration or refrigerants required)
• An air-water heat exchanger is used to remove heat from the Peltier cooling devices.
• Pneumatic pressure regulators allow operator to adjust main input line pressure, air bearing pressure and pressure supporting the load shaft
• Measures specimen beam deflection to within 0.155 µm (1,550 Å)
• Measures force to within 0.147 mN (0.015 g)
• Measures speciment beam loads from 0 to 450 grams
• Data transferred via RS-232 interface
• Meets ASTM D6648 and AASHTO T313 requirements
