Abstract:

Cracking is one of the most prevalent types of distresses in asphalt pavements. There are different cracking

index parameters that are determined from tests conducted on binders and mixtures to assess cracking

potential. The objective of this study is to compare binder and mixture parameters and evaluate the similarities

and differences between the rankings and values obtained. This study includes binder and mixture testing on

14 plant produced mixtures including three different binder grades, three binder sources, three aggregate

gradations, and mixtures containing a range of RAP and/or RAS contents. Testing included PG grading and

4mm DSR testing on the extracted and recovered binders that were long term aged. Mixture testing included

complex modulus, SVECD fatigue, and DCT testing on short term aged mixtures. Parameters evaluated

included high and low PG temperatures, ∆Tcr, Glover-Rowe parameter (binder and mix-based), R value,

dynamic modulus, phase angle, number of cycle to failure from SVECD and LVECD analysis, and fracture

energy. The results show that generally the binder parameters correlate well with each other but the mixture

parameters do not. Good correlation was observed between binder and mixture stiffness-based parameters,

but there was generally low correlation observed between binder and mixture cracking parameters for the

mixtures evaluated in this study, possibly a result of differences in aging level. Recommended future work

includes non-linear statistical analysis, incorporation of field performance, and testing on long term aged

mixtures.
