The ATS Bending Beam Rheometer 3 (BBR3) performs flexural tests on asphalt/bitumen binder and similar specimens per AASHTO T 313, AASHTO TP 87, ASTM D6648, GOST 58400.8-2019, and BS EN 14771specifications as part of the PG grading system according to Superpave. ATS the BBR3 is the of its kind to offer a state of the art internal computer system, incorporating intuitive new software and touchscreen technology. 

Load Frame Construction Integral stainless steel, frictionless construction, Loading Shaft Point In-line stainless steel with blunt point, Test Load Variable test range from 0 to 4,500 mN (459 g) standard. System maintains required test load within +/- 5 mN (0.5 g) throughout test cycle. Test Cycle Times  Cycle times for pre-load, recovery, and test load are completely operator-adjustable. Mechanical Overload Protection Standard. Temperature Measurement Platinum RTD. 

Test Weights Calibrated and traceable to NIST, Sample Supports 3mm (0.118 in) radius stainless steel spaced 101.6mm (4.00 in) apart, LVDT Displacement Transducer 0.25 in (6.35 mm) calibrated range to provide 2 μm resolution throughout testing and verification range. 

Data Display Large on-screen display of load, displacement, and bath temperature provides 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
