Rheological evaluation of asphalt binder modified with zinc oxide nanoparticles

Case Studies in Construction Materials, 2022
The use of asphalt binders modified by nanomaterials has been studied to minimize premature deterioration of the surface layer of pavements also caused by increases in traffic volume without adequate control of axle load and tire pressure.

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

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)
