Performance Related Asphalt Mixtures Characterization
This study presents the results of an experimental and exploratory analysis that correlates pavement life-cycle data of production and construction to the in-service performance. The dependency of the pavement performance with respect to four distresses; rutting, alligator, transverse, and longitudinal cracking, is investigated. In this study, the pavement information of 12 Wisconsin DOT highways is used to develop a geo-relational database. Using the developed database, an experimental plan including mixture and recovered binder testing is further used for the analysis. The results highlighted the importance of binder grading, mixture mechanical performance, and pavement age for alligator cracking. For rutting, dust to binder ration, pavement structural capacity, compaction, and dynamic mixture properties are the influential factors. Finally, for transverse thermal cracking, binder rheological properties, mixture mechanical capacity, dust to binder ration, climate conditions, and pavement structural capacity are found to be influential factors. The developed framework for this study also contributed to a better understanding of the extent to which the above-mentioned parameters are affecting performance. Based on the results, material performance limits are suggested in this study that intends to provide a basis for moving towards the performance-based mixture design. This study provides a roadmap for state highway agencies to develop their own performance-related specifications for the production and construction of flexible pavements.
