Dan G. Zollinger, Ph.D., P.E.

Dr. Dan G. Zollinger is a Research Engineer at the Texas A&M Transportation Institute (TTI) and a Professor at Texas A&M University in the Department of Civil Engineering. He is the manager for the rigid pavements program at TTI and is the Past President of the International Society for Concrete Pavements (ISCP). He is very knowledgeable of construction methods and procedures for concrete pavement systems and their effect on pavement performance. His major areas of research include concrete pavement performance, rehabilitation, behavior, and design. He was a consultant on the development of the 200x AASHTO Guide (NCHRP Project 1-37a) and played a key role in the advancement of the design of CRC pavements. He is actively engaged in pavement evaluation, pavement design, and pavement performance particularly as it may be affected by the joint seals. He has also researched for several years the structural behavior of concrete materials under field conditions and the evaluation of drainage related performance as a function of base type, drainage effectiveness, erosion resistance. He has recently played an instrumental role in the development of a new test for erosion in concrete pavements. His has worked for several years on the development of performance models for mechanistic pavement design procedures; this effort has led him to collect performance data from a variety of concrete pavement sections to validate an array of distress mechanisms for concrete pavement ranging from punch out distress to faulting. He has been involved with several projects dealing with pavement instrumentation and testing and serves on several technical committees related to the behavior of rigid pavements. In 2009, he retired from the USAR at the rank of Lt Colonel with 39 years’ service.
