Using Advanced Binder Rheological Parameters to Predict Cracking Potential of Hot-Mix Asphalt Mixtures with Modified Binders

This project seeks to improve the asphalt binder used in hot-mix asphalt (HMA) pavements to increase the performance and durability of pavements constructed in Illinois. Researchers will attempt to answer industry concerns with new testing parameters and tie the binder testing protocol developed in ICT-IDOT project R27-196-HS with mixture performance measures. The study objective is twofold: (1) evaluate the potential of advanced binder rheological parameters in predicting HMA cracking potential and (2) evaluate the potential to blend softener-modified binders with Styrene-butadiene-styrene (SBS) polymer. To accomplish the objectives of this project, base binders, softener-modified binders, and softener/polymer-modified binders will be tested at different binder and mixture levels. The relationship between binder’s rheology and mixture cracking potential will be investigated. This research will assist in the implementation of a draft special provision for softener-modified binder. Improved pavement performance and durability will allow drivers in Illinois to experience less maintenance activities and fewer construction projects.
