For the Polish (and Middle European) binders critical temperature is determined mainly by the m parameter (obtained during testing in bending beam rheometer) and resistance to aging while stiffness parameter S is typically secondary important (Pilat et al.

The bending beam
rheometer (BBR) is another primary piece of testing equipment used in the Superpave PG grading system.
The formulas of material strength are used in order to assess the strength of bending beams
When the bark side was removed from the beam, the sixth growth ring and possibly some of the fifth growth ring were lost; therefore the static bending beams
consisted of only the first five growth rings after the ice storm.
Because of many common geometries - bending beams
, torque tubes, stress sections, and load-zone designs - their part mix is well suited to CAD/CAM technology.
