Abstract

The objective of this study was to fully characterize and validate the mechanical-based aging model parameters and compared with the chemical kinetic model. This study found that level of aging applied to both asphalt binder and asphalt concrete showed differences, as verified by all of the p-values from regression analysis test, were greater than 0.05. The aging variable value decreased with the aggregate involved. The aging history dependent (k2) could be simulated the actual aging behavior as a polynomial curve. The Pearson correlation test showed that there is a strong relationship between the carbonyl content and the aging model variable.
