Critical Issues and Misconceptions in Spray-Applied (“Spray-On”) Asphalt Rejuvenation

Asphalt rejuvenation has been used for decades as a pavement preservation tool, but advancements in the category are not reflected in today’s spray-on asphalt rejuvenator (SOR) conversations. As a result, performance is often measured using outdated and sometimes proprietary frameworks, creating a disconnect in what’s being measured and what actually drives pavement performance. The challenge is not that rejuvenators lack supporting data, but that success metrics have not been reassessed as new technologies and research have emerged.

AMIGUARD™ Rapid Penetrating Emulsion Rejuvenator: An Early-Life Preservation Solution

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.
