Barry J. Dempsey recipient of asce T&DI's Robert horonjeff award
July 29, 2009
Professor Emeritus Barry J. Dempsey received the Horonjeff Award on behalf of the Board of Governors of the Transportation and Development Institute (T&DI) of the American Society of Civil Engineers (ASCE). He is recognized for his career-long outstanding contributions and achievements in air transportation engineering, teaching, research and public service.
The Horonjeff Award recognizes the contributions that Robert Horonjeff made to the aviation field through his research, teaching, practice and mentoring of furture aviation engineers. Professor Dempsey joins an elite group of aviation professionals that have received this award.
The formal presentation of the award is planned to occur at the T&DI Airfield Pavement Committee's meeting during the annual meeting of the TRB in January 2010 in Washington, D.C.

Professor Dempsey received his Ph.D. at the University of Illinois at Urbana-Champaign (UIUC) in 1969. He joined the faculty at the University of Illinois in 1969 and was promoted to Professor of Civil Engineering in 1979. Prior to his advanced degree work, Dr. Dempsey served 2 years as an engineer for the Illinois Division of Highways and 2 years as an officer in the U.S. Army Corps of Engineers. He is a registered Professional Engineer in Illinois. Dr. Dempsey is actively involved in aviation and highway transportation. He taught Airport Facilities Design for over 30 years and he is a private pilot. Dr. Dempsey was the major force for development and operation of the Advanced Transportation Research and Engineering Laboratory (ATREL) at Rantoul, Illinois and served as its Director for 10 years. He was also the Director for the FAA Center of Excellence (COE) for Airport Pavement Research for 10 years. Within the COE Dr. Dempsey initiated a very successful Summer Internship Outreach Program for Minority Students. Under his direction the COE for Airport Pavement Research became one of the more successful and productive COE programs sponsored by the FAA.
Since joining the Civil Engineering faculty, Dr. Dempsey has been conducting research in the area of climatic effects on pavement materials and systems and in airport facilities design. He has been actively performing research to determine how temperature, frost action, and moisture influence the load carrying capabilities of pavement materials and soils, and to incorporate the research findings into the design, construction, behavior, and performance of pavement systems. As part of his research, Dr. Dempsey has developed mathematical models that describe both the temperature and moisture regimes in pavement materials and pavement systems with time and as a function of climate. He has worked extensively in the areas of pavement drainage, geosynthetic materials, and the influence of climatic parameters on material properties.
Dr. Dempsey conducted extensive research to develop an interlayer stress absorbing composite (ISAC) material that is showing substantial promise for mitigating reflection cracking in asphalt concrete overlays. The ISAC material carries U.S. and foreign patents and has been used in numerous airport and highway pavement projects during the last 10 years. The University of Illinois officially Commercialized ISAC in December 2002. One of Dr. Dempsey's past projects involved making modifications and improvements to the Integrated Model for Climatic Effects on Pavements. This research was conducted at the request of the FHWA and MN Test Road. The climatic model is widely accepted for use in temperature and moisture evaluations relating to pavement design and is a major component for the AASHTO 2002 Design Guide. An extensive research project was completed for the Illinois Department of Aeronautics in 2000 to develop and evaluate a VFR lighted flyway marker system that could be used in the Chicago TCA. The purpose of this study was to improve the safety and efficiency of VFR aircraft when transitioning through TCA airspace. In this project various marker sizes, colors, and lighting systems were tested under actual VFR flight conditions at Monticello Airport and DuPage Airport.
Dr. Dempsey’s more resent research has been involved with the design and development of the full-scale Accelerated Pavement Testing Facility at ATREL. That facility became operational in March 2002. He recently completed a project to develop a successful antioxidant additive to extend the life of AC pavements as well as a project for the FAA concerning the performance of an anti-icing test site at O’Hare International Airport. The antioxidant additive is presently being patented and considered for commercialization.
