Bending beam rheometer BBR pro plus

The Bending Beam Rheometer BBR Pro Plus is a device used to test the flexural creep stiffness of asphalt binders at low temperature. It evaluates the low‑temperature cracking resistance characteristics of asphalt binders, providing test results including low‑temperature creep stiffness S(t) and the creep stiffness change rate m(t).
FEATURES
- Computer software for control and display, showing real‑time deformation, pressure, and temperature curves.
- Built‑in LVDT calibration device for simple and convenient calibration.
- High‑performance chiller enables fast cooling: 40 minutes from room temperature to -18°C, with high temperature control accuracy.
- The chiller is connected to the main unit via flexible hoses and placed separately to prevent vibration from affecting test results.
- USB communication port for easy data export.
- Overload protection and fault warning functions with buzzer alarm and fault code display.
- Stainless steel shell for aesthetics, easy cleaning, and durability.
- Adjustable test time for verifying deformation beyond 240s (default: 240s).
- Software‑configurable time points for calculation (default: 8s, 15s, 30s, 60s, 120s, 240s).
- Two‑stage air filtration to prevent impurities from affecting test accuracy.
