Two Nano Hydrated Lime (NHL) materials with particle sizes of 50 nm and 100 nm were used in this study to investigate to the effect of NHL modification on the creep and recovery of Warm Mix Asphalt (WMA) binders foamed using Advera® with respective to rutting. The NHL was added to the asphalt binder at ratios of 20%, 10%, and 5% by weight of the asphalt binder. The creep and recovery tests were performed at three different stress levels, 3Pa (creep for 100 sec. and 600 sec. recovery), 10Pa (creep for 20 sec. and 600 sec. recovery), and 50Pa (creep for 1 sec and 300 sec. recovery). The tests were performed at a temperature of 58oC. The results were also compared with the Regular Hydrated Lime (RHL) results. The overall results reveal that the neat asphalt binders foamed using advera® showed larger permanent deformation (rutting) potential compared to the binder modified with RHL and NHL foamed using Advera®. As the NHL dose increases, the non-recoverable compliance decreases (rutting decreases). It was also concluded that the application of the RHL with the normal dose (20% by weight of binder) can be replaced by adding 5% (by weight of binder) of 50 nm NHL with respective to rutting.
