Develop a Method for Selecting Low-Energy Mixing and Compaction Temperatures for Asphalt Mixtures Considering Asphalt Lubrication and Aggregate Characteristics

Current state of practice methods to determine mixing and compaction temperatures for asphalt mixtures fail to reasonably explain the mixture workability mechanism and do not consider other important properties of asphalt mix such as aggregate properties and mix gradation.

The TRB IDEA (Innovations Deserving Exploratory Analysis) Program's NCHRP IDEA Final Report for Project 246: Develop a Method for Selecting Low-Energy Mixing and Compaction Temperatures for Asphalt Mixtures Considering Asphalt Lubrication and Aggregate Characteristics explores a mthod that could improve mixture density and, therefore, asphalt mixture and flexible pavement performance.
