The TE-BBR SD 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.
The TE-BBR SD meets or exceeds ASTM, AASHTO, and SHRP provisions for flexural creep testing of asphalt binders, including ASTM D6648, AASHTO T 313, SHRP Binder Provisions.
Common applications include flexural creep of asphalt binders and low temperature characterization of crack seal under load.
