Characterization of Fatigue Properties of Binders and Mastics at Intermediate Temperatures using Dynamic Shear Rheometer

Fatigue in flexible pavements is one of the most complex and least understood phenomenon. This is because the fatigue behavior of hot mix asphalt is influenced by several factors, such as strain intensity, frequency of loading, oxidative aging, and rest period (Johnson et al, 2007). The strain amplitude and the rest period play a significant role, because some binders have an ability to heal during the time when there is no loading. Overall, binders appear to dictate the performance of hot mix asphalt because of two reasons: (1) The strains within the binder is approximately 90 times the average strain experienced within the hot mix asphalt (Johnson et al. 2007, Masad et al. 2001); (2) The phenomenon of healing and hardening that influence fatigue properties primarily occur within the binder.
