  • Bending Beam Rheometer - Pavement Interactive

    Overview. The Bending Beam Rheometer (BBR) test (see Figure 1) provides a measure of low temperature stiffness and relaxation properties of asphalt binders. These parameters give an indication of an asphalt binder ’s ability to resist low temperature cracking. The BBR is used in combination with the DTT to determine an asphalt binder’s low temperature PG grade.

  • Using Asphalt Mixture Beams in the Bending Beam Rheometer

    ABSTRACT The paper is presented to validate the use of asphalt mixture beams in the Bending Beam Rheometer (BBR) test. Experimental work was performed to address the concerns regarding the sources of variability of using asphalt mixture beams for the BBR tests. The dimensional differences on the accuracy of deflections of a beam are evaluated using finite element method and statistical analyses.
