Superpave Defined
From October 1987 through March 1993, the Strategic Highway Research Program (SHRP) conducted a $50 million research effort to develop new ways to specify, test, and design asphalt materials. The final product of the SHRP asphalt research program is a new system referred to as SuperpaveTM, which stands for Superior Performing Asphalt Pavements. It represents an improved system for specifying the components of asphalt concrete, asphalt mixture design and analysis, and asphalt pavement performance prediction.

Superpave Researchers
The Superpave Asphalt Research Program consists of a group of engineering and technical professionals who provide technical service in Superpave technology.
Dr. Yetkin Yildirim - Dr. Yetkin Yildirim is the project manager of the Superpave and Asphalt Technology Program at the University of Texas at Austin. His primary interests are in the areas of pavement materials, construction and rehabilitation. Dr. Yildirim has extensive experience with asphalt materials and their performance. Currently, he has been directing six research projects at the Superpave and Asphalt Technology Program. He also serves as a lecturer at the University of Texas at Austin, teaching classes on pavement materials, such as “Bituminous Mixture Design”, “Bituminous Materials”, and “Preventative Maintenance of Asphalt Pavements” both at the graduate and the undergraduate level.
Some of the TxDOT research projects related to asphalt materials and managed by Dr. Yildirim at the Superpave and Asphalt Technology Program include: “Toner Modified Asphalt”, “Develop Guidelines for Designing and Constructing Thin Asphalt Concrete Pavement Overlays on Continuous Reinforcement Concrete Pavement”, “Long Term Research on Bituminous Coarse Aggregate”, “Effect of Crushed Aggregates on HMA Performance”, “Comparison of Hot Poured Crack Sealant to Emulsified Asphalt Crack Sealant”, “Correlation of Field Performance to Hamburg Wheel-Tracking Test Results“, “Calculation of Mixing and Compaction Temperatures for Modified Asphalt Binders”
