Description

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.
