Abstract:

Higher traffic coupled with heavier loads led the asphalt industry to introduce polymer-modified binders to enhance the durability and strength of hot mix asphalt (HMA) pavements. When the Superpave Performance Graded (PG) binder specification (AASHTO M 320) was introduced, it was expected that all asphalt binders with the same “Performance Grade” would function the same under a similar climate and traffic condition, regardless of how those binders are produced. Since then, numerous research studies have shown that G*/ Sinδ, the high temperature specification parameter for current PG asphalt binder, is not adequate to reflect the rutting characteristics of modified binders. As such, many state DOTs have adopted supplemental specifications, also known as “PG-Plus” tests in addition to the conventional PG specifications. However, in most cases, the PG-Plus tests do not reflect the binder performance and only identify the presence of polymer in polymer-modified binders. The Multiple Stress Creep Recovery (MSCR) test, which has already been included in the latest AASHTO specifications for PG asphalt binder (AASHTO MP 19), showed potential to resolve the previously mentioned issues. Louisiana has been using various polymer and crumb rubber modified binders for a long time. With the inclusion of the MSCR test in the AASHTO MP 19 and an anticipation of its wide spread utilization, there has been a need for DOTD to verify whether the parameters such as: Jnr and MSCR percent recovery are sensitive to polymer and crumb rubber modified binders commonly used in Louisiana. This study was initiated to identify the feasibility of DOTD to make a transition to the latest MSCR-based AASHTO asphalt binder specifications.
