LS-BBR Bending Beam Rheometer (BBR)
LS-BBR Bending Beam Rheometer (BBR) is a bending beam rheometer and direct tension tester for asphalt binder testing for ASTM D6648, AASHTO T313, EN 14771 workflows.
Hybrid Refrigeration Mode
Combines Peltier elements with an external chiller for rapid cool-down from ambient to -18°C within 40 minutes with ±0.1°C precision.
Vibration Isolation Design
The chiller unit is connected via flexible hoses to eliminate mechanical resonance, ensuring zero interference with sensitive creep measurements.
Digital Metrology Suite
Equipped with an integrated LVDT calibration device and high-resolution sensors for S(t) and m-value indices.
Intelligent Fluid Dynamics
Features an adjustable magnetic stirrer in the liquid bath to ensure absolute temperature uniformity across the specimen zone.
Smart Data Management
USB-enabled data export with industrial tablet control. Pre-set intervals for 8s, 15s, 30s, 60s, 120s, and 240s testing.
Laboratory Safety Suite
Dual-stage air filtration and automated overload protection with acoustic/visual fault code alerts for mission-critical reliability.
