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)

Advances in Civil Engineering, Volume 2023, Issue 1, 2023., 2023 Growing traffic loads, soaring summer temperatures, and moisture damage will render conventional asphalt binder insufficient to maintain the performance standards of asphalt concrete pavement. Thus, it is necessary to modify the virgin asphalt using various polymers or nanomaterials.

Effects of Waste Cooking Oil on the Antiageing Ability of Bitumen
Advances in Civil Engineering, Volume 2023, Issue 1, 2023., 2023 Ageing is considered one of the significant issues faced by bituminous mixtures. The short‐term ageing phase involves a significant rise in the bitumen’s viscosity, which may lead to early raveling and cracking. Antiageing additives are prescribed to reduce the effects of short‐term ageing.

Improvement of Engineering Properties of Asphalt Binder and Mixture by Using SBS Additive Material
Advances in Civil Engineering, Volume 2023, Issue 1, 2023., 2023 Rutting, thermal cracking, and stripping are among the most severe distress types in asphalt pavement. In this study, a specified type of styrene‐butadiene‐styrene (SBS) was used as a modifier for a low viscosity asphalt binder G80/100 (PG 58‐22) to overcome the issues of the distresses in the asphalt mixture.
