Dr. Riyad Aboutaha, is an associate professor of structural engineering in the Department of Civil and Environmental Engineering at Syracuse University.  He is a Fellow of the American Concrete Institute (ACI). Dr. Aboutaha has over 40 years of construction and research experience.  In the last 32 years, he has been researching the use of new materials for renewal of civil infrastructure.  Dr. Aboutaha has offered numerous seminars and workshops on evaluation and rehabilitation of concrete bridges with CFRP composites, including some for the U.S.A.  Federal Highway Administration (FHWA), and the New York State Department of Transportation (NYSDOT).  In addition, he completed major research projects on the GFRP bar ComBAR for Schöck Bauteile GmbH of Baden-Baden, Germany, on the durability of wearing surfaces for FRP bridge decks, for NYSDOT, and most recently bridge widening using CFRP composites for Shandong DOT, China.  Prof. Aboutaha’s current research interests are in the area of economy of preventive maintenance of concrete bridges, investigation of structural failures, and alteration of structural systems using CFRP composites.
