ATS BBR2SThe improved ATS Bending Beam Rheometer (BBR2S) is engineered to perform flexural tests on asphalt binder/bitumen and similar specimens per ASTM D6648, BS EN 14771, and AASHTO T313. These tests consist of a constant force being applied to a specimen in a chilled bath in order to derive specific rates of deformation at various temperatures. Enhanced software and the ability to perform crack sealant tests expand the capabilities of the BBR2S beyond those of the original BBR2. Intuitive programming guides operators through test setup, providing a highly customizable and user-friendly experience.



  • PID temperature controller with digital display
  • Two independent platinum RTDs for precise temperature control
  • External cooling unit with temperature controller
  • Test temperatures of -40° to 25° C
  • Three-point bend test apparatus
  • Stainless steel, durable, corrosion-resistant construction
  • Meets ASTM D6648, BS EN 14771, and AASHTO T313 test standards
  • Computerized control, data acquisition, and analysis
  • Integral LVDT and temperature-compensated 500 gram load cell
  • Optional Crack Sealant Testing Hardware


New Software and Reporting

The BBR2S features the newest version of our BBR software, which includes:

  • Programmable Test Parameters – amount of force, length of time force is applied, the length of time for the specimen to recover, and the specimen size.
  • Language Options – Seven pre-programmed languages include English, Spanish, French, Chinese, German, Italian, and Arabic.
  • System Status Lights – Clearly indicate which system components need to be verified. If verification cannot occur, the software gives users the option to standardize right from the verification screen.
  • Customizable Reports – BBR2S users now also have the ability to name their samples, enter any important notes, and upload their company logo directly into their test report.


Step Disk and Gaging Kit

Each BBR2S comes with a gaging kit which includes:

  • Step Disk – Prevents movement with detent locking mechanism and the highest level of accuracy.
  • Four 50g weights, two 2g weights
  • Certified confidence beam
  • Certified compliance beam
  • Carrying case
