Study on the rheological and aging behavior of high-viscosity polyphosphoric acid modified asphalt (HVPA)

Key Points

• High-viscosity modified asphalt exhibits improved rheological properties, enhancing its durability.
• Key metrics include viscosity variations observed under thermal aging over several months.
• Analysis focuses on the rheological behavior and aging characteristics of high-viscosity asphalt mixes.
• These findings suggest potential benefits for road construction and infrastructure projects.
