Abstract
ABSTRACTDriven by Kyoto protocol to reduce the gas emission, warm mix asphalt (WMA) as an alternative of hot mix asphalt has gained huge interest among researchers. Despite many advantages, rutting resistance of WMAs is always questionable. In this study, ethylene bis(stearamide) (EBS) was used as a wax-based additive to produce WMAs. Samples were produced at three different compaction temperatures. To evaluate rutting resistance of mixtures, all cylindrical specimens were tested by dynamic creep and dynamic modulus tests at various compaction temperatures. Results indicate that rutting resistance of EBS-modified samples are remarkable, especially when compaction temperature is low.
