About Ashley

Dr. Buss is an Assistant Professor in the Department of Civil, Construction and Environmental Engineering at Iowa State University. Dr. Buss’ areas of expertise include pavement preservation, sustainable pavement systems, asphalt emulsions, asphalt materials, and materials quality. She has over 9 years of experience in infrastructure materials and pavement-related research ranging from pavement preservation strategies, asphalt emulsions, binder engineering, asphalt performance testing, pavement performance analysis, recycled asphalt materials, asphalt additives and bio-based materials. Dr. Buss serves as the principal investigator for projects investigating the effectiveness of pavement preservation in Iowa, chip seal design and specifications in Oregon, and enhancing the fundamental knowledge and use of asphalt emulsions using systematic scientific and engineering approaches. Research results have led to meaningful specification changes and updates to incorporate new technologies and address challenges. Dr. Buss’ recent research includes funded projects from the Oregon, Iowa, Minnesota, and Ohio DOTs, and industry partners. Dr. Buss is active with the Transportation Research Board (TRB) serves as a member for the Standing Committee on Design and Rehabilitation of Asphalt Pavements (AFD60), Standing Committee on Non-Binder Components of Asphalt Mixtures (AFK30), and Standing Committee on Quality Assurance Management (AFH20).
