Dan Zollinger, PhD
Senior Principal Engineer
Dr. Dan G. Zollinger is a senior principal engineer with Kittelson LLC. He is also a research engineer at the Texas A&M Transportation Institute (TTI) and a professor of civil engineering at Texas A&M University. Dr. Zollinger’s professional interests include pavement design, behavior, and performance, the mechanical and material properties of concrete, non-destructive testing of pavements, fracture and damage mechanics, and performance-based prediction modeling of concrete pavement distresses. His major areas of research include concrete pavement performance, rehabilitation, behavior, and design. Dr. Zollinger has many years of experience in the research of portland cement concrete. He is the manager of the rigid pavement program at TTI. Prior to working at TTI, he worked as a resident engineer for the SLC International Airport and a design engineer for Reinard W. Brandley, consulting airport engineer in Sacramento, California. Dr. Zollinger has been active in technical and professional societies. He is a member of the Airfield Pavement Committee of the American Society of Civil Engineers. He is a voting member of Committee 325 (Concrete Pavement Design) of American Concrete Institute. He was appointed to national office on Committee AFS60 Subsurface Drainage, and completed an appointment on Committee AFD70 Pavement Rehabilitation of the Transportation Research Board. Dr. Zollinger is a Fellow of the American Concrete Institute.
Dr. Zollinger is very knowledgeable in construction methods and procedures for concrete pavement and, more recently, roller compacted concrete (RCC) pavements. He has extensive experience in concrete pavement design and performance. He has accumulated extensive experience and background in the development of concrete pavement design procedures and was a member of the development team for the original Pavement ME. He served as the chairman of ACI Subcommittee 325.22 “Jointed Concrete Pavements,” which prepared a guide for the design of jointed concrete pavements. He has extensive experience in the instrumentation of all types of concrete pavement and monitoring pavement behavior through several TxDOT studies involved with improving the performance of concrete pavements. Through projects like these, Dr. Zollinger developed several new methods and deployment tools for concrete pavement maintenance, CoTE testing, aggregate susceptibility to ASR testing, curing quality (real-time) testing, and more recently a device to detect joint well cleanliness as a means to assess bonding conditions prior to sealant installation.
