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)

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 ...

Influence of warm mix additives on the low-temperature behavior of bitumen using the Bending Beam Rheometer (BBR) [PDF]
Construction and Building Materials, 2021 Abstract The mechanical and rheological characteristics of bitumen are crucial for the behavior and durability of the bituminous road layers. A bitumen susceptible to high temperatures can lead to plastic deformation of the bituminous layers, whereas a low temperature susceptible binder can lead to cracking of the bituminous layers.
