Anova® Asphalt Rejuvenators: reversing the impact of aging on pavement.
Pavements continually oxidize and age during their performance life, leading to durability issues as a result of increased stiffness, brittleness, and a lower ability to relax stress.
Asphalt Rejuvenators can help restore performance in a wide range of pavement types and in pavement preservation applications:
- High RAP and RAS mixtures with up to 100% RAP, while reducing construction temperatures
- Rejuvenating asphalt emulsions for surface seals and cold in place recycling
- Oils and emulsified oils for hot in place recycling and surface rejuvenating applications

- Successfully used in pavements with up to 100% RAP usage
- Enables reduction in mix costs through the use of higher recycled content
- Functions as a compaction aid - reduce required compaction temperature by at least 40F, even in high RAP pavements
- Enhances low temperature cracking resistance of asphalt mixtures
- Does not negatively impact rutting resistance of rejuvenated RAP mixture
- High flash point (in excess of 240°C/460°F) compared to petroleum-based bitumen rejuvenators, allowing safer handling without changing current processes
- Low VOCs and low volatile mass loss (as measured by the Rolling Thin Film Oven)
- Rejuvenators can enable efficient infrastructure investments, helping to improve pavement sustainability – reducing costs, increasing recycled content and supporting communities.

Case Study: City of Phoenix Gives RAP a Test Drive
With desert temperatures and metropolitan traffic, the City of Phoenix faces an ongoing challenge – brittle asphalt. When approached by Solterra Materials, the City decided to pursue the utilization of RAP in its asphalt mixes. In the following case study, learn more about how Cargill helped the City of Phoenix drive performance, cost, and environmental benefits with the incorporation of RAP.
What is an asphalt rejuvenator?
As of 2020, rejuvenator definitions in different regions are in various stages of development. Cargill has been actively participating in the advancement of knowledge in the field of asphalt rejuvenators.
Many additives have been investigated as potential asphalt recycling agents and researchers have increasingly employed the terms rejuvenator and softener. Cargill (Tabatabaee and Kurth, ISAP 2016) first proposed this functional categorization of recycling agents:
