Abstract
Nanomaterials have been used for enhancing rheological properties of bitumen and mechanical properties of asphalt mixes. In this study, the effects of nano-clay, nano-hydrated lime and hydrated lime has been investigated on fatigue behavior of bitumen. Nano hydrated lime was produced using a planetary ball mill with average particle size of 281nm. Linear Amplitude Sweep (LAS) test has been performed to evaluate fatigue properties of samples. Nano-clay was used by 2%, 4% and 6% weight of bitumen. Hydrated lime and nano-hydrated lime were used at 5%, 10% and 20% of weight of bitumen. Results showed that nanoclay at 6% (by weight of bitumen), increased fatigue life of the binder at 40% level. Specimen contained 10% nano-hydrated lime had a fatigue life 49% higher than that contained 10% hydrated lime.
