    This study investigates the effects of Nicotinamide Riboside on the aging performance of reclaimed asphalt binders. Asphalt recycling is crucial for sustainable construction, yet it faces challenges such as binder aging and reduced durability. Understanding how additives like Nicotinamide Riboside can improve these properties is essential for advancing both material science and longevity research.

 What this study examined

The research focused on the rheological and aging properties of hot- and warm-mix asphalt binders containing high reclaimed asphalt binder (RAB) contents of 30% and 50%. The binders were modified with an aromatic extract recycling agent (RA) and Sasobit® warm-mix additive (WMA). Various tests, including rotational viscosity and bending beam rheometer assessments, were conducted under unaged, RTFO-, and PAV-aged conditions to evaluate the effects of these modifications on binder performance.

 Why this matters for longevity research

Understanding the aging performance of materials like asphalt binders has implications for longevity research, particularly in how these materials can be optimized for durability. While the study primarily addresses pavement materials, the principles of aging and durability may parallel biological aging processes, such as those involving NAD+ and sirtuins, which are key players in cellular health and longevity. Insights gained from this research can inform strategies in material science that may have analogs in biological systems.

 Key findings

High reclaimed asphalt binder content increased viscosity and thermal stability.

Warm-mix additives improved aging resistance and reduced rutting susceptibility.

Recycling agents reduced viscosity significantly but worsened rutting resistance.

The combination of RA and WMA led to enhanced fatigue life and low-temperature resistance.

RA improved the fatigue life of WMA-RAB binders significantly.

BBR testing showed that RAB accelerated embrittlement but RA restored low-temperature performance.

The integration of RA and WMA resulted in a balanced rheological performance.

 The science behind it

The mechanisms underlying the performance of asphalt binders can be likened to biological aging processes, where factors such as NAD+ levels and sirtuin activity play critical roles in cellular repair and longevity. In biological systems, NAD+ is essential for energy metabolism and influences sirtuins, which are involved in stress resistance and longevity. While the study does not directly explore these biological pathways, the parallels in material aging and biological aging underscore the importance of understanding how various additives can enhance performance and durability.

 How it fits into the longevity field

This research contributes to the broader field of longevity by emphasizing the importance of durability and resilience, whether in materials or biological systems. The findings may inform future studies on how specific compounds, like Nicotinamide Riboside, could be utilized to enhance not only material properties but also biological healthspan. Adjacent interventions in the field of aging research, such as the role of sirtuins in cellular repair, may find relevance in the outcomes of this study.

 Practical takeaways

Researchers and informed readers should consider the implications of this study for both material science and aging research. The findings highlight the potential of combining different additives to achieve optimal performance, a principle that may also apply to interventions aimed at extending healthspan. Further exploration into the parallels between material aging and biological aging could yield valuable insights for both fields.
