Fountain of Youth: Asphalt Maltene Rejuvenators Add Life to Pavements

Asphalt emulsion-based rejuvenators have a place alongside chip seals and slurry surfacings in agency pavement preservation programs, experience shows.

But rejuvenators are relatively new in the game, having been introduced in the 1960s as a pavement preservation treatment. And generally, pavement management programs don’t include asphalt rejuvenators within their software due to lack of that knowledge by the program developers, and due also to established histories of chip seal or slurry wear course treatments.

The old saying that bituminous pavements start out black, and portland cement concrete pavements start out white, but both turn gray in the long run has merit because it’s true. Asphalt pavements lose essential bituminous components as they age, turning black to gray, while concrete just darkens. That loss of essential components is more than a cosmetic issue; the characteristics of an aged pavement are cracking, brittleness and loss of aggregate and oxidation, which together will compromise service life and pavement condition index number. For pavements that are in fair but not deteriorating condition, maltene-based rejuvenators applied as an emulsion can constitute the “right treatment, for the right road, at the right time.”

"I was taken aback by how the product worked. A county in Florida had 15 years of documentation and was able to demonstrate how millions of dollars had been saved preserving pavements with maltene-based rejuvenator."
