Algae-Infused Asphalt Promises Cleaner City Roads

ASU researchers warn that heat-accelerated VOCs from asphalt may harm respiratory health, with aging pavement emitting more toxic vapors; algae-infused binders can curb the most toxic emissions by ~100-fold, offering potential health and maintenance benefits. Phoenix-area tests and collaborations aim to scale safer, lower-emission asphalt for future road networks.
