Asphalt pavements begin aging immediately after construction. Both physical and chemical changes to the pavement occur as a result of oxidation, UV exposure, presence of moisture, freeze and thaw cycles, and traffic wear. Early life aging can quickly lead to severe functional distresses such as raveling and cracking and set the stage for more costly downstream structural repairs. Early-life preservation treatments are critical to extending maintenance timelines and lowering life cycle costs of asphalt pavements.
AMIGUARD™ Rapid Penetrating Emulsion Rejuvenator (RPE-R) is a spray-on, bio-based oil emulsion engineered to offset early life asphalt binder aging, reduce permeability and extend pavement life.

Why AMIGUARD RPE-R Leads in Pavement Preservation
Preserving pavement in its early life is one of the most cost-effective strategies for extending road performance and reducing long-term maintenance costs. AMIGUARD RPE-R stands out because it combines advanced rejuvenation technology with practical application benefits. From offsetting the effects of aging to enabling quick traffic return, this solution strengthens durability without compromising safety or efficiency.
Here’s why AMIGUARD RPE-R stands out to agencies and contractors:
- Offsets Early Aging: RPE-R is applied within the first few years of pavement life to address aging and delay future distresses.
- Quick Return to Traffic: Due to its engineered ability to penetrate below the surface, rather than sitting on top, roads can reopen in as little as 30 minutes under normal conditions.
- Reduces Permeability: RPE-R residue fills surface-connected air voids, reducing pavement permeability, resulting in pavements that shed water and dry faster.
- Eliminates Need for Sanding: This results in a clean and efficient application process.
- Pavement Markings Remain Visible: With its semi-transparent finish, existing markings show through after RPE-R application.
- Easy Application: No specialized equipment is required with RPE-R; standard asphalt distributors are the preferred method of application.
How AMIGUARD RPE-R Works
AMIGUARD RPE-R is engineered to meet the demands of modern asphalt mixtures and road owners alike. RPE-R emulsion is engineered with a specialized chemical package that reduces surface tension, enabling the emulsion to penetrate the pavement quickly and effectively. As the product diffuses through the interconnected void structure, it fills those voids, reducing permeability and chemically rejuvenating the existing asphalt binder.
The treatment is sprayed a light khaki or cream color and dries to a semi-transparent finish that preserves existing striping. And because of its fast-breaking formulation, traffic can be resumed soon after application, minimizing disruption to the driving public. RPE-R residue is designed to reduce the need for applying blotter or cover sand, even for dense graded asphalt pavements.
Proven Success Stories
Across the Midwest, agencies are turning to AMIGUARD RPE-R to protect their investment in newer pavements. Successful applications in Carlton County, MN and Wood County, WI demonstrate how a proactive approach to pavement management can stretch infrastructure dollars and delay the need for maintenance.

Proactive preservation strategies are some of the most effective ways to maximize infrastructure investments. When roads last longer, infrastructure dollars go further, reducing the need for costly repairs and reconstruction.
Rejuvenate the Bio-Based Way
By applying AMIGUARD RPE-R during the first few years of a pavement’s life, agencies and contractors can significantly lower life-cycle costs while improving sustainability through bio-based technology.
