Spray-on asphalt rejuvenators (SORs) have been used for decades as a pavement preservation tool, but advancements in the category are not reflected in today’s 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 As a result, performance is often measured using outdated and sometimes proprietary frameworks, creating a disconnect in what’s being measured and what actually drives pavement performance.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.
