Asphalt Binder Performance Grading for the Republic of Yemen Based on Superpave Asphalt Mix-Design
The asphalt binder is considered a temperature-sensitive viscoelastic material. Temperature can cause some common distress of asphalt pavement, such as rutting (permanent deformation), which correlated with high-temperature environments, and ...

Influence of unserviceable tires’ rubber on the mechanical performance of hot mix asphalt
This work aimed to optimize the production of hot mix asphalt (HMA) from the use of asphalt-rubber. For that, the mechanical performance of asphalt mixtures produced with different binders was evaluated: commercial asphalt-rubber (AR08), asphalt crumb ...

Crumb rubber modified asphalt (CRMA) offers several advantages such as increased rutting resistance and enhanced stability. However, few studies have explored the relation between CR size and rutting resistance of CRMA mixtures at different temperatures as well as the development of prediction models to assess the performance of CRMA mixtures ...

Rheo‐Chemical Characterization and ML‐Based Prediction of Rejuvenated RAP Binders
Reclaimed asphalt pavement (RAP) has gained significant attention in pavement engineering due to its economic and environmental benefits. However, the high stiffness and brittleness of aged RAP binders (RPB) necessitate the use of rejuvenators to restore their performance. This study evaluated the effectiveness of two commercial rejuvenators (PX and RB)
