Asphalt Binder Testing at Low Temperature: Three-Point Bending Beam Test in Dynamic Shear Rheometer [PDF]

Frontiers in Materials, 2022
A novel Three-Point Bending Beam Test (3-PBT) using a Dynamic Shear Rheometer (DSR) with linear drive motor is introduced for testing asphalt binder at low temperature conditions. This 3-PBT in DSR can be used as surrogate for Bending Beam Rheometer (BBR)

Impact of Multi-scale Asphalt Thin Beams in the Bending Beam Rheometer on the Prediction of Thermal Cracking of Bituminous Material

Procedia Engineering, 2016
AbstractAsphalt thin beams (112mm x 12.7mm x 6.35mm, length x width x thickness) in a Bending Beam Rheometer (BBR) have been used in the asphalt industry as one of methods to predict low temperature cracking properties of asphalt mixtures. Given the research work dedicated to the asphalt industry, the potential benefits of testing smaller specimens ...

Characterization of bituminous-sealants utilizing modified bending beam rheometer

Transportation Research Record: Journal of the Transportation Research Board, 2006
Early research showed that the current specification for the selection of crack sealants correlates poorly with field performance. To address this issue and help predict the low temperature properties of hot-poured bituminous sealants, a modified Bending Beam Rheometer (BBR) method is utilized. Eight sealants, with a wide range of rheological behaviors,
