Bending Beam Rheometer

The bending beam rheometer (BBR) performs flexural tests on asphalt binder and similar specimens per tests, initially developed by the Strategic Highway Research Program (SHRP), which consist of a constant force being applied to a specimen in a chilled fluid bath in order to derive specific rates of deformation at various temperatures. The complete BBR system consists of a fluid bath base unit, a three-point bend test apparatus, which is easily removed from the base unit for specimen loading and unloading, an external cooling unit with temperature controller and a calibration hardware kit with carrying case. The unit features an integral, stainless steel load frame and in-line, blunt-point loading shaft. The large, easy-to-read digital display shows load, displacement, and bath temperature for ease of setup and operation. Real-time displacement, loading, and temperature graphs are displayed during the test cycle and can be re-plotted and re-scaled as needed for easy viewing.

The BBR uses a linear, variable-displacement transducer (LVDT) with a range of 6.35mm and accuracy to ±2mm measures deflection. The temperature-compensating 500g load cell with mechanical overload protection ensures accurate load results. Safe, rapid cooling of the ethylene glycol mixture test fluid to -40° to 25°C is provided by a mechanical refrigeration system. Process temperature is controlled and monitored by two, independent, platinum RTD temperature transducers maintaining temperature stability.

The BBR comes with a pre-loaded software package, which allows for device configuration, daily verifications, test setup, test initiation, and reporting. It also includes five aluminum specimen molds with mylar strips, a Calibration Kit with required weights, and confidence beam. Calibrated test weights and a certified LVDT (NIST-traceable). The easy-to-use software allows daily verification and periodic calibration of load cell, LVDT, and RTD transducers

Dimensions: 49" x 49" x 41" (1,245 x 1,245 x 1,040mm). An adequate compressed air source must be supplied by user.
