Innovative Approaches in Asphalt Binder Modification and Performance

Dear Colleagues,

Asphalt binders are essential to the performance and longevity of road pavements, yet traditional binders face challenges such as aging, temperature fluctuations, and increasing traffic loads. To overcome these limitations, innovative approaches in binder modification, using polymers, nanomaterials, and bio-based additives, have emerged, significantly improving the mechanical and rheological properties of asphalt. These advancements enhance resistance to deformation, cracking, and environmental degradation, leading to more durable and resilient pavements.

In parallel, sustainable practices in binder modification are gaining attention. Researchers are exploring the use of recycled materials and environmentally friendly additives to reduce the ecological impact of pavement construction without compromising performance. Additionally, advanced characterization and testing methods are enabling more precise assessments of binder behavior, optimizing formulations for different climates and conditions.

This Special Issue invites original research and reviews on innovative approaches in asphalt binder modification and performance, including the following topics:

• Novel modifiers for asphalt binders;
• Advanced technologies in binder modification;
• Performance evaluation and testing methods;
• Durability and aging studies;
• Sustainable approaches in binder modification.

We look forward to your valuable contributions to advance pavement engineering and infrastructure sustainability.
