Moisture susceptibility and rutting potential of warm mix asphalt produced using foaming nozzle technology

Warm Mix Asphalt (WMA) can be produced using foam bitumen technology. In this research, using a laboratory foam bitumen producing device, WMA mixes were produced applying different mixing and compaction temperatures. With performing Marshall testing, properties of WMA mixes were determined. To compare moisture susceptibility and rutting potential of WMA and control HMA mixes, Modified Lottman (Indirect Tensile) and Wheel Tracking tests were performed on both HMA control and WMA samples. In order to improve resistance of WMA mixes against water damage, two additives were used; namely hydrated lime filler and a liquid anti-stripping agent. These were shown to improve moisture resistance of these mixes considerably. In addition, hydrated lime had a more pronounced effect in reducing rutting potential of WMA mixes.
