An SBR-based toughness enhancement for high modulus recycled asphalt binder

Key Points

• Toughness enhancement occurs with the incorporation of SBR into recycled asphalt binders, improving durability.
• The performance properties of high modulus materials demonstrate significant improvements, particularly in flexibility.
• Evaluation using mechanical testing under various conditions indicates favorable outcomes for binder usability in construction.
• This research supports the adoption of SBR for enhancing asphalt performance, calling for broader application in road construction.
