Research on Rheological Properties of warm mix asphalt binders

摘要：

　　Warm mix asphalt (WMA) has been gaining increasing popularity in recent years due to energy savings and environmental benefits.Warm mix asphalt reduces the production temperatures (mixing and compaction) while maintains the advantages of hot mix asphalt (HMA).It is becoming an attractive paving material.Therefore, it is important to understand the rheological behavior of asphalt binders changes with temperature and proportion of the additives.In this study, rheological properties of one commonly used binder PG 70-28 were evaluated, with and without additives (Sasobit(R) and Aspha-Min(R)) as the warm asphalt additives, by means of conventional tests as well as dynamic mechanical analysis using Dynamic Shearing Rheometer (DSR).The rheological test included viscosity, temperature sweep and frequency sweep.
