A new asphalt-binding material called AirDuo developed by Ellie Fini, an associate professor in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools, diminishes emissions of toxic fumes while also increasing the materials overall sustainability. That especially helps to reduce health hazards to workers installing the material. The binding mixture is made from low-carbon, bio-based materials that offer an alternative to more toxic petroleum products. More testing of the material at ASU and possibly in Tucson and Flagstaff will aim to increase the effectiveness of AirDuo paving. The article previously appeared on the ASU News website.
