Achieving Optimum Rutting Resistance of Bitumen Using Oxidation and Polymers - A Laboratory Study

This study was designed to investigate the changes in rheological and rutting resistance of selected bitumen binders due to a special modification process called Binary Modified (BM). BM includes a specific refining process in which an oxidation technique is used to adjust molecular structure of asphalts combined with a limited polymer concentration to enhance resistance to rutting, fatigue, aging, and low temperature cracking. This paper includes a comprehensive set of testing data showing the improvement in rutting properties. The results show the promise of combining the specific oxidation technique with polymer addition to optimize cost and rutting performance under varying loading and temperature conditions.
