Preserving Pavement Early with a Rapid Penetrating Emulsion – Rejuvenator (RPE-R)

Evergreen Roadworks applies RPE-R in Hendricks County 

When it comes to asphalt pavement, the clock is ticking. From the moment a road is laid, oxidation and UV exposure begin to degrade the asphalt binder, accelerating aging and leading to costly repairs down the line. The good news? There is a smarter way to fight back—applying a Rapid Penetrating Emulsion – Rejuvenator (RPE-R) before the damage accelerates. 

The Problem: Aging Starts Immediately 

Even in the first few years of a pavement’s life, subtle changes occur at the surface. Asphalt film loss, water permeability issues and mastic loss between aggregates set the stage for cracking and surface distress. By year four or five, thermal cracking often appears, and maintenance costs grow exponentially.  

The Strategy: Treat Early, Save Big 

Early preservation is the most cost-effective approach to pavement management. In a pavement’s early years, the rate of deterioration is slow and the cost to maintain quality is low. But after several years, the rate of change accelerates dramatically and pavement condition begins to decline rapidly. This is why early intervention is critical: rejuvenating the binder before significant distress occurs can lock in performance and delay costly repairs. 

The principle is simple: you cannot rejuvenate rock. There must be enough asphalt binder at the surface for the treatment to react with. Applying RPE-R within the first two years of a pavement’s life ensures the rejuvenator can penetrate and restore the binder before aging takes hold. 

The Solution: AMIGUARD™ RPE-R 

Unlike traditional fog seals that only coat the surface, RPE-R has a unique chemical package that was designed to break surface tension and easily penetrate up to 3/8 inch deep, delivering rejuvenating agents deep into the pavement. Its bio-based formula restores aged asphalt binder, seals out water and offsets the effects of oxidation—all while preserving surface texture and pavement markings.

Key Advantages of RPE-R 

• Minimal Impact on Macrotexture – Maintains road safety and performance. 
• No Sanding Required – A true single-pass application. 
• Preserves Pavement Markings – No need for costly restriping. 
• Quick Return to Traffic – Roads reopen in just 15–30 minutes. 
• Deep Rejuvenation – Fills surface voids and closes pores up to 3/8” deep to inhibit water permeation. 

This innovative treatment is designed for roads in their first two years of life, when the asphalt binder is still intact but beginning to age. By breaking surface tension and permeating interconnected voids, RPE-R chemically rejuvenates the pavement—delaying distress and extending service life. 

A Forward-Thinking Approach 

Early-life preservation is not just smart—it is essential. By choosing RPE-R, agencies can reduce long-term costs, minimize disruption and keep roads performing at their best for years to come.
