Abstract
For quality assurance and quality control purposes, suppliers and users of asphalt binders follow the widely used dynamic shear rheometer (DSR) test method (AASHTO T 315) to capture viscoelastic properties of polymer-modified binders (PMBs), warm mix asphalt (WMA)- and reclaimed asphalt pavement (RAP)- modified binders even though it is designed for unmodified asphalt binders. AASHTO T 315 is inadequate to characterize the aforementioned binders because of the relatively small impact of the phase angle and strain levels on the rutting and fatigue factors, respectively. The recently balloted multiple stress creep recovery (MSCR) test (AASHTO T 350) results can better relate the laboratory-based and field rutting of PMBs and additive-modified binders. In the current study, Superpave, MSCR, frequency and linear amplitude sweep (LAS) tests were performed to evaluate viscoelastic properties of selected asphalt binders approved in Arkansas and Texas. A total of 65 binder samples were tested in the laboratory. Of these, 8 were unmodified binders, 24 were PMBs, 27 were WMA-additive modified, and 6 were RAP modified binders. The non-recoverable compliance and MSCR percent recovery data of the tested binders were analyzed for grading and establishing the MSCR percent recovery criteria for local service temperature and traffic conditions. The developed guidelines are expected to be helpful for transportation agencies in Arkansas and Texas to adopt the MSCR test method in their quality control process.
