This study was conducted to evaluate rheological, damage and performance properties of Binary Modified (BM) Asphalts. The research investigated the effectiveness of a specific processing with or without polymer to improve fatigue properties. BM includes a refining process in which an oxidation technique is used to adjust molecular structure of asphalts combined with a limited polymer concentration to achieve better performance. The changes in workability of binders due to modification were evaluated using rotational viscosity at various temperatures. Also, the performance under cyclic loading was evaluated using a Dynamic Shear Rheomter following a protocol recently developed at various stress and temperature levels. The results show that significant improvements in fatigue can be achieved with the binary modification with minimal effect on workability. The process appears to be adjustable to achieve various levels of improvements.<\div>

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.<\div>
