Sensitivity of Mixture Performance Tests to Identical PG Binders from Different Suppliers

This paper presents an overview of research efforts undertaken to evaluate the sensitivity of several mixture performance tests on identical Performance Grade (PG) binders obtained from different suppliers in the State of Arizona. The laboratory testing program included the dynamic modulus and the repeated load/flow number tests. Asphalt mixtures were collected from four sections on a project constructed in northern Arizona. This project was unique in that all four asphalt concrete mixtures had the same aggregate structure, but used PG 76-16 binders obtained from four different suppliers. Based on the test results, the tests were sensitive to the variations in properties of the PG binders obtained from different suppliers. This was also confirmed through statistical analysis and comparison with the binder test data. In addition, the binder and mixture data from the Arizona project were input into the Mechanistic-Empirical Pavement Design Guide (MEPDG) and design simulations were run to compare rutting and fatigue cracking associated with each of the four PG76-16 binders included in this study. Significant statistical differences in both distress mechanisms were also observed for the different mixes.
