• 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.
