• Abstract:
  The fundamental objective of asphalt mix design is to select an aggregate skeleton and asphalt binder content that balances constructability and performance. High performance mixtures that protect against rutting, cracking and moisture damage are difficult to achieve while still maintaining a workable mixture. When designing a pavement mixture, the Wisconsin Department of Transportation (WisDOT) follows a modified version of the Superpave mix design procedure and does not employ performance testing other than assessing moisture susceptibility using a modified Lottman (Tensile Strength Ratio) test. ; Since the adoption of the Superpave method, advancements have been made in asphalt binder and mixture technologies that warrant reevaluation of design policy. The goal of this research was to identify which performance-related properties of mixtures to evaluate, which tests to conduct and how this information will be incorporated into WisDOT’s asphalt pavement mixture design and quality management program.
